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. Sorry, your blog cannot share posts by email. 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. 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. But your review makes me think they may be worth a shot. 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. The response may be given in … It’s easy and painless! Going for a higher end model would be my choice though. 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. Half an hour of this got me to a balance that seemed to match seamlessly with the speaker’s upper bass. I start looking forward to browsing even more websites written by Thanks for teh great review. Okay, here's my question. 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. 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 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. REL T-Zero. € 399,00. zum Angebot Fernsehservice Horvath Infos AGB. Just bought two of these to match my B&W 685 s2.

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. Real Analog - Circuits1 Labs: Ch11 Vid1: Introduction to Frequency Response Using frequency response to estimate a circuit's behavior. This is the range from 50 to 90 Hz. I have a fact-finding project. 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. In fact, the very comprehensive manual states: “ALWAYS connect using the REL HIGH-LEVEL input, unless your system simply cannot accommodate this”. 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. 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. However, in some situations when there are two or more … 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. Ô¾ô? Amplifier Type: Class D . – Frequency-response tests are, in general, simple and can be made accurately by readily-available equipment, e.g., dynamic signal analyzer.

Price: £350 (per subwoofer) Manufactured by: REL Ltd. URL: rel.net. They’re totally accepted and even loved in the home theatre environment, but somewhat scorned in stereo environments by much of the audiophile community. 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. 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. 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. With the REL in place, there was a more even front-to-back distribution of bass. The Rel T Zero is small, discrete, and beautiful. Finish: Black or White Lacquer. – Correlation between frequency and transient responses is indirect, except for 2nd-order systems. I guess it should be circular pseudo-frequency, or I don't know how you say that. All of our designs are true Sub-Bass Systems, meaning they are designed to reproduce T ZERO Sub-Bass System Many or most loudspeakers emphasize the mid-bass. Post was not sent - check your email addresses! 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. always thought the bottom end lacked some punch although the mid and highs are very sweet. REL T-Zero << Previous Next >> Click to enlarge : Details . 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. 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). However, the sub integrated with the room better than the speakers do, creating fewer high pressure bass nodes. The frequency response of continuous-time systems gives another view, just as it did for discrete-time systems in Chapter 6. My question is about the 'overlap' between the quads and the REL. 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. The cleaner midrange and better overall bass quality came as no surprise, because I’ve indulged in this experiment before. Lower Frequency Response: 38 Hz at -6 dB in room.

REL’s subwoofer isn’t for the big boomers, but will subtly augment the sound of systems in smaller rooms, writes Ashley Kramer. 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. Never heard these before. I would say it lacks the punch and precision of larger subs for movies, but for music I never think about it. Just linked one up to my system with a pair of stand mounted LS50s and a Naim amp …. I use "the" in scare quotes since, of course, there are often multiple cycles in time series data. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. ASHLEY KRAMER. 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. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. 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. 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. REL T-ZERO Subwoofer . 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. end. 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. 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). want. ’…Å_î“ #Hǘ$¶š ÕŒÛrÇÆâ¿€S| %!æÈ.

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. We have an open concept kitchen, living room, and dining room which is about 8m by 8m, and it fill in very nicely. Tel: +44 (0)1656 768777 Lower Frequency Response: 38 Hz at -6 dB in room. find a blog page that provides all of the information i 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. 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. Input Connectors: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. The company is into good subwoofers, the kind that are intended to make music, not go boom. So REL products are engineered for integration into stereo systems. Save my name, email, and website in this browser for the next time I comment. Norstone Stylum 2. Schutzsystem. 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!) 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. Frequency response functions are complex functions, with real and imaginary components. 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”. Glad I read this review it sounds great, they are such a powerful little subwoofer! SUBWOOFERS ARE A bit of a conundrum. 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. The T-Zero didn’t slow the bass down at all, proving easily able to keep up with the speakers in terms of timing. H‰œTkOÛ0ı�_q?¦5¶ã¼$„£LL †´‡Pn–G»”şû];iìñUÍóŞsÏ9>NéP˜2ŠĞœ"#åĞKgá\;§‰s˜°{ The concept of frequency response is again motivated by applying a single sinusoid. Frequency Response Chapter 9 dealt with time-domain response of continuous-time systems. 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. 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. Gain Control Range: 80 dB. The volume is set at about half, and the crossover is around 45. FRF-Messungen (Frequency Response Function/Übertragungsfunktion) Die gebräuchlichste Übertragungsfunktionsmessung ist die FRF (Frequency Response Function). I don't think pseudo is a word all by itself, not even in 18.03, circular. Weight: 6.8kg. 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. 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. Your email address will not be published. The frequency is "the" period at which seasonal cycles repeat. They would be laking for my needs a little. H‰\“Ën£@E÷|E/“EÄ«»*HÈ’c'’“Dã™ÀĞö �µñÂ? If you want a small extension to the bass response of a system like this you could certainly do worse than this little job. 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. The compact form factor obviously means that the huge drivers usually associated with subwoofers just aren’t feasible, so REL has implemented a single 6.5-inch (165mm) long-throw downward firing driver housed in a sealed cabinet and driven by 100 watts of Class D amplification. 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. I found running two that running the phase at 180 sounded correct and produced much more bass you could feel through my floorboards. Bottom end extension is limited (as expected) with REL claiming a modest 38 Hz at -6dB in room. 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. 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. Price: £299 (per subwoofer) Manufactured by: REL Ltd. URL: www.rel.net. I actually have recently been undertaking study upon this theme In this way, the REL is fed the exact signal that is fed to the main speakers.”. Apparently, wanting to repeat this huge success, the company included a miniature T-ZERO in its assortment. Your email address will not be published. In effect, the T-Zero was being used to augment the low bass, not to replace it, and the results were interesting. Input Impedance: High-Level: 150k, Low Level: 10k, .1/LFE: 10k ohms. 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. Amplifier: 100W Class D. Dimensions (W×H×D): 216 ×241 ×260 mm. 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.

This paragraph will assist the internet visitors for creating new weblog or even a blog from start to freqz can accept other parameters, such as a sampling frequency or a vector of arbitrary frequency points. 36 Bewertungen Lieferzeit 2-7 Werktage . If you start out with something like G(s) = (s +ω n), then factor as G(s) = ω n * s ω n +1 +. A beautiful finish on this thing as well though mine’s not really on display … In a word – impressive. freqz returns the complex frequency response in vector h, and the actual frequency points in vector w in rad/s. 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. http://souforum.com/. Your website has definitely offered me personally with just the facts that I actually required. Lo and behold, exactly as promised by the Viganoni theory, the midrange was clearer and the bass seemed slightly more articulate. 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. Okay, so this is its pseudo-period, pseudo-frequency, pseudo-circular frequency, but that's hopeless. 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. 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. 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. 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. Entertainment for Grownups – Hi-Fi, Home Theatre, Music, Movies, TV & Film, Gaming, Gadgets and more! The Frequency Response Function for LTI Systems • The output of an LTI system can be … A frequency response function can be formed from either measured data or analytical functions. 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 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. 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.

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. without breaking the bank, a REL T-Zero V2 (or preferably, two) can’t be beaten. (adsbygoogle = window.adsbygoogle || []).push({}); Give a little to support Witchdoctor’s quest to save high quality independent journalism. 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. To obtain an estimated frequency response, the block simultaneously: Fully Electronic with SET-SAFE Description. 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. 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. 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. Just donate $5 or $10 to our PressPatron account by clicking on the button below. The example below finds the 256-point frequency response for a 12th-order Chebyshev Type I filter. If … Power Output: 100 Watts (RMS) Phase Switch: Yes, 0 or 180 degrees. 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. A frequency response function expresses the structural response to an applied force as a function of frequency. 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. And its diminutive scale allows it to all-but-hide among the … 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. 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. REL is a British company that’s dedicated to making subwoofers, but not just any subwoofers. Vorkasse, Kreditkarte, EPS € 12,-. Finish: Black or White Lacquer. Learn how your comment data is processed. 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. 4.9. Draw the gain term (ω n)separatelyfromthezeroterm(s/ω n +1). 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. Page 11 REL Set-Up Made Simple REL products are not traditional subwoofers, but are true Sub-Bass Systems. 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.
