The T-Zero is the baby of the T-Series, and baby is an apt term because as far as subs go, this thing is tiny. Entertainment for Grownups – Hi-Fi, Home Theatre, Music, Movies, TV & Film, Gaming, Gadgets and more! Amplifier: 100W Class D. Dimensions (WxHxD): 216 x 241 x 260 mm. So I cranked up the crossover and level knobs only to be greeted by a profoundly overblown low bass, even with the speakers now being rolled off at the bottom. I actually have recently been undertaking study upon this theme Amplifier Type: Class D . Just bought two of these to match my B&W 685 s2. find a blog page that provides all of the information i However, in some situations when there are two or more … Running it with the power amps providing roll off and pass-through duties, the effects were much the same, only more dramatic as far as hazy audio recollection leads me to believe – there certainly seems to be something in Audio Pro’s ACE-Bass (Amplifier-Controlled Euphonic Bass) technology. Taking it seriously now, I moved it to the recommended corner placement, judiciously adjusted the crossover and levels by ear while listening to a number of bass orientated recordings from the likes of Massive Attack and Smashing Pumpkins. The frequency response at all frequencies from zero to half the sampling rate can be represented by a modulus spectrum of ... Modal resonances usually appear as circles when a Frequency Response Function (FRF) is plotted in real versus imaginary form or as clearly defined peaks when the FRF is plotted as a modulus spectrum. Lower Frequency Response: 38 Hz at -6 dB in room. Instead of the default option of a RCA LFE input found on most subs, REL prefers to use a high-level (speaker level) input in a hi-fi environment. Your website has definitely offered me personally with just the facts that I actually required. Power Output: 100 Watts (RMS) Phase Switch: Yes, 0 or 180 degrees. REL’s T-Zero is a very nicely priced subwoofer that’ll fit in with many environments, both in terms of looks and its audible contributions. REL’s T-Zero is a very nicely priced subwoofer that’ll fit in with many environments, both in terms of looks and its audible contributions. Apparently, wanting to repeat this huge success, the company included a miniature T-ZERO in its assortment. There’s method to this seeming madness, according to REL: “The purpose of connecting to the speaker output terminals is one of the unique secrets of REL’s success. Your email address will not be published. They may also be represented in terms of magnitude and phase. That’s due to design and size, but of course its limited extension means that you wouldn’t use it to add bass to a set of speakers that reach way down low already.

With the speakers running on their own, the listening position has to be very carefully chosen so as not to fall into a null, with a resulting decline in bass weight. This is the range from 50 to 90 Hz. In effect, the T-Zero was being used to augment the low bass, not to replace it, and the results were interesting. The Frequency Response Function for LTI Systems • The output of an LTI system can be … In due time the British REL literally shocked the market by ultra-compact Quake subwoofer - it was considered before that a true bass machine simply must have big sizes. Finish: Black or White Lacquer. Fortunately, with my amplification chain there are a number of ways to connect a sub, expressly intended to roll off the signal sent to the main speakers, allowing them to do what they do best (upper bass upwards) and passing the full signal to the sub, thereby allowing it to do its job and recreate the low bass. Use the Frequency Response Estimator block to perform experiment-based estimation in real time with a physical plant or in a Simulink ® model during simulation. The T-Zero didn’t slow the bass down at all, proving easily able to keep up with the speakers in terms of timing. That’s not really subwoofer territory according to most people, especially the aforementioned Mr Viganoni, who reckons a sub needs to be able to get to 20Hz at -3dB. The cabinet is described as being “super stiff” and designed to drive up the resonant frequency to allow the damping of the “instrument-grade bracing” to be more effective. Input Impedance: High-Level: 150k, Low Level: 10k, .1/LFE: 10k ohms. for any real, even impulse-response .Thus, the frequency response is a real, even function of .A real frequency response has phase zero when it is positive, and phase when it is negative.

We have an open concept kitchen, living room, and dining room which is about 8m by 8m, and it fill in very nicely. Having heard how good this set up can sound, it seemed the logical approach, and in this case, I used the cut inputs on the power amps to feed them a rolled off signal and ran  RCA interconnects into the sub – combined with an adapter into its low level input. Gain Control Range: 80 dB. T-ZERO: RRP: 749.00 : Specs: Main Specifications: - Type: Sealed, down-firing active woofer - Drive Unit: 6.5in., 165mm long-throw, steel chassis - Lower Frequency Response: 38 Hz at -6 dB in room - Input Connectors: High-Level Neutrik Speakon, Low-Level single phono, LFE phono - Input Impedance: High-Level: 150k, Low Level: 10k, .1/LFE: 10k ohms Then there are those subwoofers that just aren’t musical: they’re great for making big explosions bigger but less well suited to recreating the sound of a double bass or kick drum – good luck integrating one of those to a stereo system and ending up with something that sounds good. Lower Frequency Response: 38 Hz at -6 dB in room Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono Amplifier: 100W Class D Dimensions (WxHxD): 216 x 241 x 260 mm Weight: 6.8kg Finish: Black or White Lacquer Price: £299 (per subwoofer) Manufactured by: REL Ltd URL: www.rel.net Tel: +44 (0)1656 768777 + A few years back, I bought an Audio Pro sub at a liquidation sale.

I start looking forward to browsing even more websites written by My question is about the 'overlap' between the quads and the REL. ASHLEY KRAMER. http://souforum.com/. The concept of frequency response is again motivated by applying a single sinusoid. always thought the bottom end lacked some punch although the mid and highs are very sweet. Lower Frequency Response: 38 Hz at -6 dB in room. The ability to fit in with rolled off speaker environments or smaller speakers – which is its natural habitat – and to be able to delicately augment a set of bigger floorstanders, is due to the T-Zero’s ability to provide just enough bass for the job at hand, without getting carried away. At 216 x 241 x 260 mm (W x H x D) including the feet, the T-Zero doesn’t exactly strike one as the kind of unit you’d use to get down low, but it certainly impresses from a looks perspective. Frequency response is $1/(1−ce^{iw})$, if you want to get amplitude information you just need to get the magnitude of this complex function and its phase will be the inverse of the phase of $1/(1−ce^{iw})$ or If you start out with something like G(s) = (s +ω n), then factor as G(s) = ω n * s ω n +1 +. They would be laking for my needs a little. I have a fact-finding project. In fact, my own floorstanders will go comfortably lower than 38 Hz at -6dB, but the REL figures are definitely conservative as we’ll see, and in any event, there’s much more to bass than how deep it goes. It’s a musical little beast, definitely suited for stereo environments, and in the right system, it’s a pleasure to listen to (I’ve heard more articulate units, albeit at a price point well above the REL’s) but users need to bear its ultimate limitations in mind when deciding to buy – if you want 20Hz flat, then you need a bigger box, end of story.

The cleaner midrange and better overall bass quality came as no surprise, because I’ve indulged in this experiment before. Description. Tel: +44 (0)1656 768777 Thanks for teh great review. Frequency-response methods can be used to supplement root locus: ... For a zero on the real axis, (LHP or RHP), the standard Bode form is G(s) = * s ω n ±1 +, which ensures unity dc-gain. TECHNICAL SPECIFICATIONS Type: Sealed, down-firing active woofer Drive Unit: 165mm long-throw, alloy cone, steel chassis Lower Frequency Response: 38 Hz at -6 dB in room Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono Amplifier: 100W Class D Despite the comparatively small driver and cabinet, the T-Zero can move a fair amount of air, but it doesn’t like to be driven outside its comfort zone. In this way, the REL is fed the exact signal that is fed to the main speakers.”. Page 11 REL Set-Up Made Simple REL products are not traditional subwoofers, but are true Sub-Bass Systems. Bass extension didn’t seem to be dramatically deeper than that produced by the speakers when they’re running full-range, even with the promised 9dB of acoustic amplification delivered by the corner loading – the laws of physics can only be helped along to a certain limited degree. What can be a mighty pain, was more or less a simple matter of dialling down the sub to get its contribution to subtly add to the bottom end of the speakers without creating too much of a bass peak. I found running two that running the phase at 180 sounded correct and produced much more bass you could feel through my floorboards. H‰\“Ën£@E÷|E/“EÄ«»*HÈ’c'’“Dã™ÀĞö �µñÂ? But your review makes me think they may be worth a shot. Frequency response functions are complex functions, with real and imaginary components. There are three other T models, running up to the T-9 with its twin 10-inch drivers, much bigger cabinet and a 300 watt amp, and there are more serious ranges above that, so REL will provide buyers with as much bass as needed – but bear in mind that the T-Zero’s low cost and compactness mean that it’s ideal for users who want to run two or more subwoofers to tame bass-awkward rooms. It’s reasonably dead and dull when given a scientific hard knock with a calibrated knuckle, but that’s not too difficult to pull off when the longest edge of your cabinet is less than 300mm long. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. Weight: 6.8kg. Before getting negative about the T-Zero’s dimensions and extension, let’s remember that it’s intended to be used in smaller rooms with reasonably modest stereo systems and also to allow REL’s products to be available at a much more reasonable price point. Very impressed so far, the little Rel has no problem integrating into the sound stage and after a few minutes tweaking with the levels all is very pleasant. – Frequency-response tests are, in general, simple and can be made accurately by readily-available equipment, e.g., dynamic signal analyzer. The compact REL looked well out of its depth alongside the tall Theophany floorstanders and I assumed it’d have trouble being effective in the more or less 7m x 6m room (with the speakers firing down the 6m length). The midrange benefits vanished as expected, but what was surprising was just how easy it was to get the REL to integrate with the system. 36 Bewertungen Lieferzeit 2-7 Werktage . (adsbygoogle = window.adsbygoogle || []).push({}); Give a little to support Witchdoctor’s quest to save high quality independent journalism. The company is into good subwoofers, the kind that are intended to make music, not go boom. Learn how your comment data is processed. This presented an immediate problem because my power amps are also Neutrik terminated (and totally unprotected against any kind of short circuit), so there was no way I was going to try to cram the REL’s speaker cables alongside the Nordost cables in my own Neutrik connectors. Schutzsystem. Going for a higher end model would be my choice though. Weight: 6.8kg. With the REL in place, there was a more even front-to-back distribution of bass. Vorkasse, Kreditkarte, EPS € 12,-. you down the road, and will take a look right here first of all the very next time freqz returns the complex frequency response in vector h, and the actual frequency points in vector w in rad/s. Like other T-Series woofers, the T-Zero uses a custom-made woofer, a REL designed 6.5" Ultra-Long Throw, mated to a wicked fast Class D amplifier delivering a potent and ultra-green 100 Watts. The price means that it’s possible and tempting to run a pair of them because two is almost always better than one when it comes to subs. It’s finished in nine coats of hand rubbed black (or white) piano gloss lacquer, further polished on a rouging wheel using jewellery buffing compound and then hand polishing using micro fiber cloth and automotive waxes. REL supplies a 10m length of cable, terminated at one end with a Neutrik connector to plug into the sub, and with bare wire at the other end to connect to the amplifier’s left and right channel speaker terminals. The volume is set at about half, and the crossover is around 45. The premise of T-Zero is to bring quality, the full REL connectivity suite, long throw drivers and powerful, reliable amplifiers to a new lower price point and dimension.

The T-Zero was left in-situ for a fairly long review period and at no stage did I feel it had provided any detrimental effects to the audio performance of my hi-hi system. And its diminutive scale allows it to all-but-hide among the … A beautiful finish on this thing as well though mine’s not really on display … In the real world, you’ll often see frequency response specifications quote a range of frequencies, such as 20 Hz – 20 kHz, followed by the amount of variation in the frequency response quoted in decibels, such as +/- 6 dB. REL’s subwoofer isn’t for the big boomers, but will subtly augment the sound of systems in smaller rooms, writes Ashley Kramer. The price means that it’s possible and tempting to run a pair of them because two is almost always better than one when it comes to subs. I would say it lacks the punch and precision of larger subs for movies, but for music I never think about it. By connecting to the high-level input on the REL from the amplifier, you build forward the sonic signature of your main system, including the tonal balance and timing cues of the entire electronics chain. Just donate $5 or $10 to our PressPatron account by clicking on the button below. freqz can accept other parameters, such as a sampling frequency or a vector of arbitrary frequency points. Of course, there’ll be some combining of output of the two bass systems and this is usually what causes problems when trying to get a sub to work in a system with bigger speakers; it’s much easier with speakers that aren’t quite as bass capable. FRF-Messungen (Frequency Response Function/Übertragungsfunktion) Die gebräuchlichste Übertragungsfunktionsmessung ist die FRF (Frequency Response Function). Designed by WPZOOM. – Correlation between frequency and transient responses is indirect, except for 2nd-order systems. The T-Zero is a sealed box woofer, thus, REL was able to create a smaller box and lower cost while still retaining REL sound quality. REL T-Zero << Previous Next >> Click to enlarge : Details . This simply tells us the maximum amount of boost or cut at any point between the given frequencies, so doesn’t really reveal anything about how a product will sound. In fact, the very comprehensive manual states: “ALWAYS connect using the REL HIGH-LEVEL input, unless your system simply cannot accommodate this”. So REL products are engineered for integration into stereo systems. A REL is designed to augment the performance of “full range” speaker systems in order to provide, in certain cases, linear response below 12 Hz. We at REL believe this is an incomplete approach and that loudspeakers need to be extended in the lower frequencies for true full range reproduction. Your email address will not be published. Required fields are marked *. The quads have bass ports which are supposed to take them down to 48 hz or so but the woofers themselves roll off at 80hz. I don't think pseudo is a word all by itself, not even in 18.03, circular. Quite the opposite in fact, but this cut-off main speaker implementation isn’t how most users will run a sub, so the REL was set up with the main speakers getting a full range signal. Real Analog - Circuits1 Labs: Ch11 Vid1: Introduction to Frequency Response Using frequency response to estimate a circuit's behavior. end. 4.9. I guess it should be circular pseudo-frequency, or I don't know how you say that. Fully Electronic with SET-SAFE Ähnlich wie die FFT-Analyse ist FRF typisch für ein System, welches eine von einem bekannten Eingangssignal gemessene Rückmeldung hat. without breaking the bank, a REL T-Zero V2 (or preferably, two) can’t be beaten. Norstone Stylum 2. Lo and behold, exactly as promised by the Viganoni theory, the midrange was clearer and the bass seemed slightly more articulate.

There’s method to this seeming madness, according to REL: “The purpose of connecting to the speaker output terminals is one of the unique secrets of REL’s success. Your email address will not be published. They may also be represented in terms of magnitude and phase. That’s due to design and size, but of course its limited extension means that you wouldn’t use it to add bass to a set of speakers that reach way down low already.

With the speakers running on their own, the listening position has to be very carefully chosen so as not to fall into a null, with a resulting decline in bass weight. This is the range from 50 to 90 Hz. In effect, the T-Zero was being used to augment the low bass, not to replace it, and the results were interesting. The Frequency Response Function for LTI Systems • The output of an LTI system can be … In due time the British REL literally shocked the market by ultra-compact Quake subwoofer - it was considered before that a true bass machine simply must have big sizes. Finish: Black or White Lacquer. Fortunately, with my amplification chain there are a number of ways to connect a sub, expressly intended to roll off the signal sent to the main speakers, allowing them to do what they do best (upper bass upwards) and passing the full signal to the sub, thereby allowing it to do its job and recreate the low bass. Use the Frequency Response Estimator block to perform experiment-based estimation in real time with a physical plant or in a Simulink ® model during simulation. The T-Zero didn’t slow the bass down at all, proving easily able to keep up with the speakers in terms of timing. That’s not really subwoofer territory according to most people, especially the aforementioned Mr Viganoni, who reckons a sub needs to be able to get to 20Hz at -3dB. The cabinet is described as being “super stiff” and designed to drive up the resonant frequency to allow the damping of the “instrument-grade bracing” to be more effective. Input Impedance: High-Level: 150k, Low Level: 10k, .1/LFE: 10k ohms. for any real, even impulse-response .Thus, the frequency response is a real, even function of .A real frequency response has phase zero when it is positive, and phase when it is negative.

We have an open concept kitchen, living room, and dining room which is about 8m by 8m, and it fill in very nicely. Having heard how good this set up can sound, it seemed the logical approach, and in this case, I used the cut inputs on the power amps to feed them a rolled off signal and ran  RCA interconnects into the sub – combined with an adapter into its low level input. Gain Control Range: 80 dB. T-ZERO: RRP: 749.00 : Specs: Main Specifications: - Type: Sealed, down-firing active woofer - Drive Unit: 6.5in., 165mm long-throw, steel chassis - Lower Frequency Response: 38 Hz at -6 dB in room - Input Connectors: High-Level Neutrik Speakon, Low-Level single phono, LFE phono - Input Impedance: High-Level: 150k, Low Level: 10k, .1/LFE: 10k ohms Then there are those subwoofers that just aren’t musical: they’re great for making big explosions bigger but less well suited to recreating the sound of a double bass or kick drum – good luck integrating one of those to a stereo system and ending up with something that sounds good. Lower Frequency Response: 38 Hz at -6 dB in room Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono Amplifier: 100W Class D Dimensions (WxHxD): 216 x 241 x 260 mm Weight: 6.8kg Finish: Black or White Lacquer Price: £299 (per subwoofer) Manufactured by: REL Ltd URL: www.rel.net Tel: +44 (0)1656 768777 + A few years back, I bought an Audio Pro sub at a liquidation sale.

I start looking forward to browsing even more websites written by My question is about the 'overlap' between the quads and the REL. ASHLEY KRAMER. http://souforum.com/. The concept of frequency response is again motivated by applying a single sinusoid. always thought the bottom end lacked some punch although the mid and highs are very sweet. Lower Frequency Response: 38 Hz at -6 dB in room. The ability to fit in with rolled off speaker environments or smaller speakers – which is its natural habitat – and to be able to delicately augment a set of bigger floorstanders, is due to the T-Zero’s ability to provide just enough bass for the job at hand, without getting carried away. At 216 x 241 x 260 mm (W x H x D) including the feet, the T-Zero doesn’t exactly strike one as the kind of unit you’d use to get down low, but it certainly impresses from a looks perspective. Frequency response is $1/(1−ce^{iw})$, if you want to get amplitude information you just need to get the magnitude of this complex function and its phase will be the inverse of the phase of $1/(1−ce^{iw})$ or If you start out with something like G(s) = (s +ω n), then factor as G(s) = ω n * s ω n +1 +. They would be laking for my needs a little. I have a fact-finding project. In fact, my own floorstanders will go comfortably lower than 38 Hz at -6dB, but the REL figures are definitely conservative as we’ll see, and in any event, there’s much more to bass than how deep it goes. It’s a musical little beast, definitely suited for stereo environments, and in the right system, it’s a pleasure to listen to (I’ve heard more articulate units, albeit at a price point well above the REL’s) but users need to bear its ultimate limitations in mind when deciding to buy – if you want 20Hz flat, then you need a bigger box, end of story.

The cleaner midrange and better overall bass quality came as no surprise, because I’ve indulged in this experiment before. Description. Tel: +44 (0)1656 768777 Thanks for teh great review. Frequency-response methods can be used to supplement root locus: ... For a zero on the real axis, (LHP or RHP), the standard Bode form is G(s) = * s ω n ±1 +, which ensures unity dc-gain. TECHNICAL SPECIFICATIONS Type: Sealed, down-firing active woofer Drive Unit: 165mm long-throw, alloy cone, steel chassis Lower Frequency Response: 38 Hz at -6 dB in room Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono Amplifier: 100W Class D Despite the comparatively small driver and cabinet, the T-Zero can move a fair amount of air, but it doesn’t like to be driven outside its comfort zone. In this way, the REL is fed the exact signal that is fed to the main speakers.”. Page 11 REL Set-Up Made Simple REL products are not traditional subwoofers, but are true Sub-Bass Systems. Bass extension didn’t seem to be dramatically deeper than that produced by the speakers when they’re running full-range, even with the promised 9dB of acoustic amplification delivered by the corner loading – the laws of physics can only be helped along to a certain limited degree. What can be a mighty pain, was more or less a simple matter of dialling down the sub to get its contribution to subtly add to the bottom end of the speakers without creating too much of a bass peak. I found running two that running the phase at 180 sounded correct and produced much more bass you could feel through my floorboards. H‰\“Ën£@E÷|E/“EÄ«»*HÈ’c'’“Dã™ÀĞö �µñÂ? But your review makes me think they may be worth a shot. Frequency response functions are complex functions, with real and imaginary components. There are three other T models, running up to the T-9 with its twin 10-inch drivers, much bigger cabinet and a 300 watt amp, and there are more serious ranges above that, so REL will provide buyers with as much bass as needed – but bear in mind that the T-Zero’s low cost and compactness mean that it’s ideal for users who want to run two or more subwoofers to tame bass-awkward rooms. It’s reasonably dead and dull when given a scientific hard knock with a calibrated knuckle, but that’s not too difficult to pull off when the longest edge of your cabinet is less than 300mm long. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. Weight: 6.8kg. Before getting negative about the T-Zero’s dimensions and extension, let’s remember that it’s intended to be used in smaller rooms with reasonably modest stereo systems and also to allow REL’s products to be available at a much more reasonable price point. Very impressed so far, the little Rel has no problem integrating into the sound stage and after a few minutes tweaking with the levels all is very pleasant. – Frequency-response tests are, in general, simple and can be made accurately by readily-available equipment, e.g., dynamic signal analyzer. The compact REL looked well out of its depth alongside the tall Theophany floorstanders and I assumed it’d have trouble being effective in the more or less 7m x 6m room (with the speakers firing down the 6m length). The midrange benefits vanished as expected, but what was surprising was just how easy it was to get the REL to integrate with the system. 36 Bewertungen Lieferzeit 2-7 Werktage . (adsbygoogle = window.adsbygoogle || []).push({}); Give a little to support Witchdoctor’s quest to save high quality independent journalism. The company is into good subwoofers, the kind that are intended to make music, not go boom. Learn how your comment data is processed. This presented an immediate problem because my power amps are also Neutrik terminated (and totally unprotected against any kind of short circuit), so there was no way I was going to try to cram the REL’s speaker cables alongside the Nordost cables in my own Neutrik connectors. Schutzsystem. Going for a higher end model would be my choice though. Weight: 6.8kg. With the REL in place, there was a more even front-to-back distribution of bass. Vorkasse, Kreditkarte, EPS € 12,-. you down the road, and will take a look right here first of all the very next time freqz returns the complex frequency response in vector h, and the actual frequency points in vector w in rad/s. Like other T-Series woofers, the T-Zero uses a custom-made woofer, a REL designed 6.5" Ultra-Long Throw, mated to a wicked fast Class D amplifier delivering a potent and ultra-green 100 Watts. The price means that it’s possible and tempting to run a pair of them because two is almost always better than one when it comes to subs. It’s finished in nine coats of hand rubbed black (or white) piano gloss lacquer, further polished on a rouging wheel using jewellery buffing compound and then hand polishing using micro fiber cloth and automotive waxes. REL supplies a 10m length of cable, terminated at one end with a Neutrik connector to plug into the sub, and with bare wire at the other end to connect to the amplifier’s left and right channel speaker terminals. The volume is set at about half, and the crossover is around 45. The premise of T-Zero is to bring quality, the full REL connectivity suite, long throw drivers and powerful, reliable amplifiers to a new lower price point and dimension.

The T-Zero was left in-situ for a fairly long review period and at no stage did I feel it had provided any detrimental effects to the audio performance of my hi-hi system. And its diminutive scale allows it to all-but-hide among the … A beautiful finish on this thing as well though mine’s not really on display … In the real world, you’ll often see frequency response specifications quote a range of frequencies, such as 20 Hz – 20 kHz, followed by the amount of variation in the frequency response quoted in decibels, such as +/- 6 dB. REL’s subwoofer isn’t for the big boomers, but will subtly augment the sound of systems in smaller rooms, writes Ashley Kramer. The price means that it’s possible and tempting to run a pair of them because two is almost always better than one when it comes to subs. I would say it lacks the punch and precision of larger subs for movies, but for music I never think about it. By connecting to the high-level input on the REL from the amplifier, you build forward the sonic signature of your main system, including the tonal balance and timing cues of the entire electronics chain. Just donate $5 or $10 to our PressPatron account by clicking on the button below. freqz can accept other parameters, such as a sampling frequency or a vector of arbitrary frequency points. Of course, there’ll be some combining of output of the two bass systems and this is usually what causes problems when trying to get a sub to work in a system with bigger speakers; it’s much easier with speakers that aren’t quite as bass capable. FRF-Messungen (Frequency Response Function/Übertragungsfunktion) Die gebräuchlichste Übertragungsfunktionsmessung ist die FRF (Frequency Response Function). Designed by WPZOOM. – Correlation between frequency and transient responses is indirect, except for 2nd-order systems. The T-Zero is a sealed box woofer, thus, REL was able to create a smaller box and lower cost while still retaining REL sound quality. REL T-Zero << Previous Next >> Click to enlarge : Details . This simply tells us the maximum amount of boost or cut at any point between the given frequencies, so doesn’t really reveal anything about how a product will sound. In fact, the very comprehensive manual states: “ALWAYS connect using the REL HIGH-LEVEL input, unless your system simply cannot accommodate this”. So REL products are engineered for integration into stereo systems. A REL is designed to augment the performance of “full range” speaker systems in order to provide, in certain cases, linear response below 12 Hz. We at REL believe this is an incomplete approach and that loudspeakers need to be extended in the lower frequencies for true full range reproduction. Your email address will not be published. Required fields are marked *. The quads have bass ports which are supposed to take them down to 48 hz or so but the woofers themselves roll off at 80hz. I don't think pseudo is a word all by itself, not even in 18.03, circular. Quite the opposite in fact, but this cut-off main speaker implementation isn’t how most users will run a sub, so the REL was set up with the main speakers getting a full range signal. Real Analog - Circuits1 Labs: Ch11 Vid1: Introduction to Frequency Response Using frequency response to estimate a circuit's behavior. end. 4.9. I guess it should be circular pseudo-frequency, or I don't know how you say that. Fully Electronic with SET-SAFE Ähnlich wie die FFT-Analyse ist FRF typisch für ein System, welches eine von einem bekannten Eingangssignal gemessene Rückmeldung hat. without breaking the bank, a REL T-Zero V2 (or preferably, two) can’t be beaten. Norstone Stylum 2. Lo and behold, exactly as promised by the Viganoni theory, the midrange was clearer and the bass seemed slightly more articulate. When it comes to hooking up the T-Zero, users will find that REL takes a different approach to many subwoofer manufacturers.

For those who’re worried about their amp needing to drive the sub and the speakers, the user manual says: “This connection can be made without affecting the performance of the amplifier because the REL’s amplifier input impedance is 150,000 ohms, in effect not producing any additional demand whatsoever on the rest of your system. A LFE input is also provided, and the speaker level and the LFE input can be run simultaneously and set up differently with their own controls to allow users to effectively have a “hi-fi sub” and a “home theatre sub”. We utilized 5 full coats of lacquer, and solid aluminium feet and badging because REL owners understand quality must extend throughout a product, not just in the most obvious locations. The T-Zero is fitted with aluminium feet with a matching badge on top, and even the bolts holding on the control panel are the polished T-304 stainless steel type – this little sub is beautifully put together, especially considering the price. I use "the" in scare quotes since, of course, there are often multiple cycles in time series data. We utilized 5 full coats of lacquer, and solid aluminium feet and badging because REL owners understand quality must extend throughout a product, not just in the most obvious locations. Ô¾ô? Presented with the opportunity to review one of the T-Series units, I jumped at the chance because I’m the proud owner of a five box amplification system that’s expressly been designed to work in a 2.1 layout. The Rel T Zero is small, discrete, and beautiful. Glad I read this review it sounds great, they are such a powerful little subwoofer! REL T-ZERO Subwoofer . Okay, so this is its pseudo-period, pseudo-frequency, pseudo-circular frequency, but that's hopeless. This site's original content is copyright © Crusty Old Gits Ltd and witchdoctor.co.nz. ’…Å_î“ #Hǘ$¶š ÕŒÛrÇÆâ¿€S| %!æÈ. They’re totally accepted and even loved in the home theatre environment, but somewhat scorned in stereo environments by much of the audiophile community. Franco would no doubt argue that even the biggest speakers still need to be rolled off because their low bass is probably a distortion-laden nightmare, but at that point, you’d need a much bigger sub. All of our designs are true Sub-Bass Systems, meaning they are designed to reproduce If you want a small extension to the bass response of a system like this you could certainly do worse than this little job. Okay, here's my question. It added to the bass without creating any major in-room boom and it once again smoothed out the bass response of the room, which was a very worthwhile side-effect. Never heard these before. Save my name, email, and website in this browser for the next time I comment. Finish: Black or White Lacquer. A frequency response function expresses the structural response to an applied force as a function of frequency. A frequency response function can be formed from either measured data or analytical functions. This site uses Akismet to reduce spam. The theory of a subwoofer in a stereo system is sound,  because low bass is probably the most difficult part of the frequency spectrum to generate properly (unless you have big speakers, and even then, the results are by no means assured) and subwoofers are nothing if not low bass generators. The frequency is "the" period at which seasonal cycles repeat. This paragraph will assist the internet visitors for creating new weblog or even a blog from start to Input Connectors: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. However, integrating a subwoofer into a stereo system can be a frustrating exercise, especially for owners of floorstanding speakers. Draw the gain term (ω n)separatelyfromthezeroterm(s/ω n +1). The frequency response of continuous-time systems gives another view, just as it did for discrete-time systems in Chapter 6. Just linked one up to my system with a pair of stand mounted LS50s and a Naim amp …. Tzero is built using a super stiff cabinet construction that drives the resonant frequency higher so it is more easily damped by our instrument-grade bracing. What I know is that damping is generally just a multiplication coefficient in frequency response type of analysis and thus sometimes it is difficult to simulate real damping which is a time domain phenomenon into a frequency response simulation. Um den Frequenzgang eines mechanischen Systems zu messen, muss das … The REL T-Zero, the baby of the company's subwoofer range, measures way less than a cubic foot and weighs just 6.8kg, but packs a 16.5cm down-firing long-throw driver powered by a 100W class D amp – the first time such and amp has been used in a REL sub. The rear panel is host to more or less the usual sub controls and inputs – with a low level input plus the LFE and high level speaker input. However, the sub integrated with the room better than the speakers do, creating fewer high pressure bass nodes. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. The designer of my amps is Franco Viganoni, a man who’s utterly convinced that bass can only be properly generated by a good subwoofer from a specific brand (Audio Pro, if you must know), and as much as he’d frown on the idea of another brand of sub being used with his amps, the little T-Zero was an intriguing concept that begged for a listen. T-Zero is built using a super stiff cabinet construction that drives the resonant frequency higher so it is more easily damped by our instrument-grade bracing. Price: £299 (per subwoofer) Manufactured by: REL Ltd. URL: www.rel.net. Lower Frequency Response: 38 Hz at -6 dB in room. It’s easy and painless! Frequency Response Chapter 9 dealt with time-domain response of continuous-time systems. REL T-Zero. REL T-Zero (Farbe: High Gloss White), 6.5" Mikro Aktivsubwoofer Stück (Art# HD-008333) Preis vom: 22.05.2020, 12:40:42 (Preis kann jetzt höher sein!) In a word – impressive. Half an hour of this got me to a balance that seemed to match seamlessly with the speaker’s upper bass. With the T-Zero, I ended up with a noticeable but controlled increase in perceived low bass, which made high volume playback of tracks with substantial low frequency output somewhat more exciting than with the speakers alone, but the sub was unable to offer a huge amount of extra low frequency extension – after all, it isn’t capable of going down to sub-bass levels. T ZERO Sub-Bass System Many or most loudspeakers emphasize the mid-bass. The example below finds the 256-point frequency response for a 12th-order Chebyshev Type I filter. For instance, daily data often exhibit weekly patterns (a frequency of 7) and yearly patterns (a frequency of 365 or 365.25 - the difference often does not matter). SUBWOOFERS ARE A bit of a conundrum. for some time, and it seems to have taken a long time to Post was not sent - check your email addresses!

The T-Zero is the baby of the T-Series, and baby is an apt term because as far as subs go, this thing is tiny. Entertainment for Grownups – Hi-Fi, Home Theatre, Music, Movies, TV & Film, Gaming, Gadgets and more! Amplifier: 100W Class D. Dimensions (WxHxD): 216 x 241 x 260 mm. So I cranked up the crossover and level knobs only to be greeted by a profoundly overblown low bass, even with the speakers now being rolled off at the bottom. I actually have recently been undertaking study upon this theme Amplifier Type: Class D . Just bought two of these to match my B&W 685 s2. find a blog page that provides all of the information i However, in some situations when there are two or more … Running it with the power amps providing roll off and pass-through duties, the effects were much the same, only more dramatic as far as hazy audio recollection leads me to believe – there certainly seems to be something in Audio Pro’s ACE-Bass (Amplifier-Controlled Euphonic Bass) technology. Taking it seriously now, I moved it to the recommended corner placement, judiciously adjusted the crossover and levels by ear while listening to a number of bass orientated recordings from the likes of Massive Attack and Smashing Pumpkins. The frequency response at all frequencies from zero to half the sampling rate can be represented by a modulus spectrum of ... Modal resonances usually appear as circles when a Frequency Response Function (FRF) is plotted in real versus imaginary form or as clearly defined peaks when the FRF is plotted as a modulus spectrum. Lower Frequency Response: 38 Hz at -6 dB in room. Instead of the default option of a RCA LFE input found on most subs, REL prefers to use a high-level (speaker level) input in a hi-fi environment. Your website has definitely offered me personally with just the facts that I actually required. Power Output: 100 Watts (RMS) Phase Switch: Yes, 0 or 180 degrees. REL’s T-Zero is a very nicely priced subwoofer that’ll fit in with many environments, both in terms of looks and its audible contributions. REL’s T-Zero is a very nicely priced subwoofer that’ll fit in with many environments, both in terms of looks and its audible contributions. Apparently, wanting to repeat this huge success, the company included a miniature T-ZERO in its assortment. There’s method to this seeming madness, according to REL: “The purpose of connecting to the speaker output terminals is one of the unique secrets of REL’s success. Your email address will not be published. They may also be represented in terms of magnitude and phase. That’s due to design and size, but of course its limited extension means that you wouldn’t use it to add bass to a set of speakers that reach way down low already.

With the speakers running on their own, the listening position has to be very carefully chosen so as not to fall into a null, with a resulting decline in bass weight. This is the range from 50 to 90 Hz. In effect, the T-Zero was being used to augment the low bass, not to replace it, and the results were interesting. The Frequency Response Function for LTI Systems • The output of an LTI system can be … In due time the British REL literally shocked the market by ultra-compact Quake subwoofer - it was considered before that a true bass machine simply must have big sizes. Finish: Black or White Lacquer. Fortunately, with my amplification chain there are a number of ways to connect a sub, expressly intended to roll off the signal sent to the main speakers, allowing them to do what they do best (upper bass upwards) and passing the full signal to the sub, thereby allowing it to do its job and recreate the low bass. Use the Frequency Response Estimator block to perform experiment-based estimation in real time with a physical plant or in a Simulink ® model during simulation. The T-Zero didn’t slow the bass down at all, proving easily able to keep up with the speakers in terms of timing. That’s not really subwoofer territory according to most people, especially the aforementioned Mr Viganoni, who reckons a sub needs to be able to get to 20Hz at -3dB. The cabinet is described as being “super stiff” and designed to drive up the resonant frequency to allow the damping of the “instrument-grade bracing” to be more effective. Input Impedance: High-Level: 150k, Low Level: 10k, .1/LFE: 10k ohms. for any real, even impulse-response .Thus, the frequency response is a real, even function of .A real frequency response has phase zero when it is positive, and phase when it is negative.

We have an open concept kitchen, living room, and dining room which is about 8m by 8m, and it fill in very nicely. Having heard how good this set up can sound, it seemed the logical approach, and in this case, I used the cut inputs on the power amps to feed them a rolled off signal and ran  RCA interconnects into the sub – combined with an adapter into its low level input. Gain Control Range: 80 dB. T-ZERO: RRP: 749.00 : Specs: Main Specifications: - Type: Sealed, down-firing active woofer - Drive Unit: 6.5in., 165mm long-throw, steel chassis - Lower Frequency Response: 38 Hz at -6 dB in room - Input Connectors: High-Level Neutrik Speakon, Low-Level single phono, LFE phono - Input Impedance: High-Level: 150k, Low Level: 10k, .1/LFE: 10k ohms Then there are those subwoofers that just aren’t musical: they’re great for making big explosions bigger but less well suited to recreating the sound of a double bass or kick drum – good luck integrating one of those to a stereo system and ending up with something that sounds good. Lower Frequency Response: 38 Hz at -6 dB in room Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono Amplifier: 100W Class D Dimensions (WxHxD): 216 x 241 x 260 mm Weight: 6.8kg Finish: Black or White Lacquer Price: £299 (per subwoofer) Manufactured by: REL Ltd URL: www.rel.net Tel: +44 (0)1656 768777 + A few years back, I bought an Audio Pro sub at a liquidation sale.

I start looking forward to browsing even more websites written by My question is about the 'overlap' between the quads and the REL. ASHLEY KRAMER. http://souforum.com/. The concept of frequency response is again motivated by applying a single sinusoid. always thought the bottom end lacked some punch although the mid and highs are very sweet. Lower Frequency Response: 38 Hz at -6 dB in room. The ability to fit in with rolled off speaker environments or smaller speakers – which is its natural habitat – and to be able to delicately augment a set of bigger floorstanders, is due to the T-Zero’s ability to provide just enough bass for the job at hand, without getting carried away. At 216 x 241 x 260 mm (W x H x D) including the feet, the T-Zero doesn’t exactly strike one as the kind of unit you’d use to get down low, but it certainly impresses from a looks perspective. Frequency response is $1/(1−ce^{iw})$, if you want to get amplitude information you just need to get the magnitude of this complex function and its phase will be the inverse of the phase of $1/(1−ce^{iw})$ or If you start out with something like G(s) = (s +ω n), then factor as G(s) = ω n * s ω n +1 +. They would be laking for my needs a little. I have a fact-finding project. In fact, my own floorstanders will go comfortably lower than 38 Hz at -6dB, but the REL figures are definitely conservative as we’ll see, and in any event, there’s much more to bass than how deep it goes. It’s a musical little beast, definitely suited for stereo environments, and in the right system, it’s a pleasure to listen to (I’ve heard more articulate units, albeit at a price point well above the REL’s) but users need to bear its ultimate limitations in mind when deciding to buy – if you want 20Hz flat, then you need a bigger box, end of story.

The cleaner midrange and better overall bass quality came as no surprise, because I’ve indulged in this experiment before. Description. Tel: +44 (0)1656 768777 Thanks for teh great review. Frequency-response methods can be used to supplement root locus: ... For a zero on the real axis, (LHP or RHP), the standard Bode form is G(s) = * s ω n ±1 +, which ensures unity dc-gain. TECHNICAL SPECIFICATIONS Type: Sealed, down-firing active woofer Drive Unit: 165mm long-throw, alloy cone, steel chassis Lower Frequency Response: 38 Hz at -6 dB in room Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono Amplifier: 100W Class D Despite the comparatively small driver and cabinet, the T-Zero can move a fair amount of air, but it doesn’t like to be driven outside its comfort zone. In this way, the REL is fed the exact signal that is fed to the main speakers.”. Page 11 REL Set-Up Made Simple REL products are not traditional subwoofers, but are true Sub-Bass Systems. Bass extension didn’t seem to be dramatically deeper than that produced by the speakers when they’re running full-range, even with the promised 9dB of acoustic amplification delivered by the corner loading – the laws of physics can only be helped along to a certain limited degree. What can be a mighty pain, was more or less a simple matter of dialling down the sub to get its contribution to subtly add to the bottom end of the speakers without creating too much of a bass peak. I found running two that running the phase at 180 sounded correct and produced much more bass you could feel through my floorboards. H‰\“Ën£@E÷|E/“EÄ«»*HÈ’c'’“Dã™ÀĞö �µñÂ? But your review makes me think they may be worth a shot. Frequency response functions are complex functions, with real and imaginary components. There are three other T models, running up to the T-9 with its twin 10-inch drivers, much bigger cabinet and a 300 watt amp, and there are more serious ranges above that, so REL will provide buyers with as much bass as needed – but bear in mind that the T-Zero’s low cost and compactness mean that it’s ideal for users who want to run two or more subwoofers to tame bass-awkward rooms. It’s reasonably dead and dull when given a scientific hard knock with a calibrated knuckle, but that’s not too difficult to pull off when the longest edge of your cabinet is less than 300mm long. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. Weight: 6.8kg. Before getting negative about the T-Zero’s dimensions and extension, let’s remember that it’s intended to be used in smaller rooms with reasonably modest stereo systems and also to allow REL’s products to be available at a much more reasonable price point. Very impressed so far, the little Rel has no problem integrating into the sound stage and after a few minutes tweaking with the levels all is very pleasant. – Frequency-response tests are, in general, simple and can be made accurately by readily-available equipment, e.g., dynamic signal analyzer. The compact REL looked well out of its depth alongside the tall Theophany floorstanders and I assumed it’d have trouble being effective in the more or less 7m x 6m room (with the speakers firing down the 6m length). The midrange benefits vanished as expected, but what was surprising was just how easy it was to get the REL to integrate with the system. 36 Bewertungen Lieferzeit 2-7 Werktage . (adsbygoogle = window.adsbygoogle || []).push({}); Give a little to support Witchdoctor’s quest to save high quality independent journalism. The company is into good subwoofers, the kind that are intended to make music, not go boom. Learn how your comment data is processed. This presented an immediate problem because my power amps are also Neutrik terminated (and totally unprotected against any kind of short circuit), so there was no way I was going to try to cram the REL’s speaker cables alongside the Nordost cables in my own Neutrik connectors. Schutzsystem. Going for a higher end model would be my choice though. Weight: 6.8kg. With the REL in place, there was a more even front-to-back distribution of bass. Vorkasse, Kreditkarte, EPS € 12,-. you down the road, and will take a look right here first of all the very next time freqz returns the complex frequency response in vector h, and the actual frequency points in vector w in rad/s. Like other T-Series woofers, the T-Zero uses a custom-made woofer, a REL designed 6.5" Ultra-Long Throw, mated to a wicked fast Class D amplifier delivering a potent and ultra-green 100 Watts. The price means that it’s possible and tempting to run a pair of them because two is almost always better than one when it comes to subs. It’s finished in nine coats of hand rubbed black (or white) piano gloss lacquer, further polished on a rouging wheel using jewellery buffing compound and then hand polishing using micro fiber cloth and automotive waxes. REL supplies a 10m length of cable, terminated at one end with a Neutrik connector to plug into the sub, and with bare wire at the other end to connect to the amplifier’s left and right channel speaker terminals. The volume is set at about half, and the crossover is around 45. The premise of T-Zero is to bring quality, the full REL connectivity suite, long throw drivers and powerful, reliable amplifiers to a new lower price point and dimension.

The T-Zero was left in-situ for a fairly long review period and at no stage did I feel it had provided any detrimental effects to the audio performance of my hi-hi system. And its diminutive scale allows it to all-but-hide among the … A beautiful finish on this thing as well though mine’s not really on display … In the real world, you’ll often see frequency response specifications quote a range of frequencies, such as 20 Hz – 20 kHz, followed by the amount of variation in the frequency response quoted in decibels, such as +/- 6 dB. REL’s subwoofer isn’t for the big boomers, but will subtly augment the sound of systems in smaller rooms, writes Ashley Kramer. The price means that it’s possible and tempting to run a pair of them because two is almost always better than one when it comes to subs. I would say it lacks the punch and precision of larger subs for movies, but for music I never think about it. By connecting to the high-level input on the REL from the amplifier, you build forward the sonic signature of your main system, including the tonal balance and timing cues of the entire electronics chain. Just donate $5 or $10 to our PressPatron account by clicking on the button below. freqz can accept other parameters, such as a sampling frequency or a vector of arbitrary frequency points. Of course, there’ll be some combining of output of the two bass systems and this is usually what causes problems when trying to get a sub to work in a system with bigger speakers; it’s much easier with speakers that aren’t quite as bass capable. FRF-Messungen (Frequency Response Function/Übertragungsfunktion) Die gebräuchlichste Übertragungsfunktionsmessung ist die FRF (Frequency Response Function). Designed by WPZOOM. – Correlation between frequency and transient responses is indirect, except for 2nd-order systems. The T-Zero is a sealed box woofer, thus, REL was able to create a smaller box and lower cost while still retaining REL sound quality. REL T-Zero << Previous Next >> Click to enlarge : Details . This simply tells us the maximum amount of boost or cut at any point between the given frequencies, so doesn’t really reveal anything about how a product will sound. In fact, the very comprehensive manual states: “ALWAYS connect using the REL HIGH-LEVEL input, unless your system simply cannot accommodate this”. So REL products are engineered for integration into stereo systems. A REL is designed to augment the performance of “full range” speaker systems in order to provide, in certain cases, linear response below 12 Hz. We at REL believe this is an incomplete approach and that loudspeakers need to be extended in the lower frequencies for true full range reproduction. Your email address will not be published. Required fields are marked *. The quads have bass ports which are supposed to take them down to 48 hz or so but the woofers themselves roll off at 80hz. I don't think pseudo is a word all by itself, not even in 18.03, circular. Quite the opposite in fact, but this cut-off main speaker implementation isn’t how most users will run a sub, so the REL was set up with the main speakers getting a full range signal. Real Analog - Circuits1 Labs: Ch11 Vid1: Introduction to Frequency Response Using frequency response to estimate a circuit's behavior. end. 4.9. I guess it should be circular pseudo-frequency, or I don't know how you say that. Fully Electronic with SET-SAFE Ähnlich wie die FFT-Analyse ist FRF typisch für ein System, welches eine von einem bekannten Eingangssignal gemessene Rückmeldung hat. without breaking the bank, a REL T-Zero V2 (or preferably, two) can’t be beaten. Norstone Stylum 2. Lo and behold, exactly as promised by the Viganoni theory, the midrange was clearer and the bass seemed slightly more articulate. When it comes to hooking up the T-Zero, users will find that REL takes a different approach to many subwoofer manufacturers.
