Norstone Stylum 2. Going for a higher end model would be my choice though. They’re totally accepted and even loved in the home theatre environment, but somewhat scorned in stereo environments by much of the audiophile community. Description. I don't think pseudo is a word all by itself, not even in 18.03, circular. 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. 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. 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. Schutzsystem. In fact, the very comprehensive manual states: “ALWAYS connect using the REL HIGH-LEVEL input, unless your system simply cannot accommodate this”. A frequency response function expresses the structural response to an applied force as a function of frequency.

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. They may also be represented in terms of magnitude and phase. Sorry, your blog cannot share posts by email. They would be laking for my needs a little. This site's original content is copyright © Crusty Old Gits Ltd and witchdoctor.co.nz. I actually have recently been undertaking study upon this theme I have a fact-finding project. Ähnlich wie die FFT-Analyse ist FRF typisch für ein System, welches eine von einem bekannten Eingangssignal gemessene Rückmeldung hat. The concept of frequency response is again motivated by applying a single sinusoid. However, the sub integrated with the room better than the speakers do, creating fewer high pressure bass nodes. 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. Glad I read this review it sounds great, they are such a powerful little subwoofer! 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. Apparently, wanting to repeat this huge success, the company included a miniature T-ZERO in its assortment. The Rel T Zero is small, discrete, and beautiful. without breaking the bank, a REL T-Zero V2 (or preferably, two) can’t be beaten. http://souforum.com/. T ZERO Sub-Bass System Many or most loudspeakers emphasize the mid-bass. All of our designs are true Sub-Bass Systems, meaning they are designed to reproduce 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. My question is about the 'overlap' between the quads and the REL. REL T-Zero. Half an hour of this got me to a balance that seemed to match seamlessly with the speaker’s upper bass. With the REL in place, there was a more even front-to-back distribution of bass. 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. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. Your email address will not be published. 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. 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 example below finds the 256-point frequency response for a 12th-order Chebyshev Type I filter. 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 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 found running two that running the phase at 180 sounded correct and produced much more bass you could feel through my floorboards. 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. When it comes to hooking up the T-Zero, users will find that REL takes a different approach to many subwoofer manufacturers. 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. But your review makes me think they may be worth a shot. Lower Frequency Response: 38 Hz at -6 dB in room. The Frequency Response Function for LTI Systems • The output of an LTI system can be … 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. The volume is set at about half, and the crossover is around 45. 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. Just bought two of these to match my B&W 685 s2. 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. This paragraph will assist the internet visitors for creating new weblog or even a blog from start to 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 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). 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. 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. Input Connectors: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. 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. 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 + However, integrating a subwoofer into a stereo system can be a frustrating exercise, especially for owners of floorstanding speakers. 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. In a word – impressive. 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 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 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. Amplifier Type: Class D . 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. 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. A few years back, I bought an Audio Pro sub at a liquidation sale. Okay, so this is its pseudo-period, pseudo-frequency, pseudo-circular frequency, but that's hopeless. 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. We have an open concept kitchen, living room, and dining room which is about 8m by 8m, and it fill in very nicely. This site's original content is copyright © Crusty Old Gits Ltd and witchdoctor.co.nz. 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”. 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. freqz can accept other parameters, such as a sampling frequency or a vector of arbitrary frequency points. Weight: 6.8kg. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. Your website has definitely offered me personally with just the facts that I actually required. In this way, the REL is fed the exact signal that is fed to the main speakers.”. Just donate $5 or $10 to our PressPatron account by clicking on the button below. Designed by WPZOOM. 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. 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. I guess it should be circular pseudo-frequency, or I don't know how you say that. 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. always thought the bottom end lacked some punch although the mid and highs are very sweet. SUBWOOFERS ARE A bit of a conundrum. Ô¾ô? end. 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!) 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. 36 Bewertungen Lieferzeit 2-7 Werktage . 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. – Correlation between frequency and transient responses is indirect, except for 2nd-order systems. 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). 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 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. 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. Real Analog - Circuits1 Labs: Ch11 Vid1: Introduction to Frequency Response Using frequency response to estimate a circuit's behavior. you down the road, and will take a look right here first of all the very next time 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. freqz returns the complex frequency response in vector h, and the actual frequency points in vector w in rad/s. 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. Bottom end extension is limited (as expected) with REL claiming a modest 38 Hz at -6dB in room. Um den Frequenzgang eines mechanischen Systems zu messen, muss das … REL Manufacturer REL Model T/zero Black Product Dimensions 26.67 x 21.59 x 24.13 cm; 6.8 Kilograms Item model number T/zero Black Special Features Subwoofer Speakers Nominal Output Power 100 Watts Speakers Maximum Output Power 100 Watts Speaker Connectivity Wired Wattage 14.00 Batteries Included No Batteries Required No Connector Type Wired This is the range from 50 to 90 Hz. 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. 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 Lower Frequency Response: 38 Hz at -6 dB in room. 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. The frequency response of continuous-time systems gives another view, just as it did for discrete-time systems in Chapter 6. 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. Real Imag ω = 50 ⇒ Y X = 0.89∠−27 ...

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. This site uses Akismet to reduce spam. 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. Input Impedance: High-Level: 150k, Low Level: 10k, .1/LFE: 10k ohms. 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. 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. Required fields are marked *. So REL products are engineered for integration into stereo systems. 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. Okay, here's my question. 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. Vorkasse, Kreditkarte, EPS € 12,-. 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. Page 11 REL Set-Up Made Simple REL products are not traditional subwoofers, but are true Sub-Bass Systems. If you want a small extension to the bass response of a system like this you could certainly do worse than this little job. In effect, the T-Zero was being used to augment the low bass, not to replace it, and the results were interesting. The gloss surface is gorgeous! for some time, and it seems to have taken a long time to I use "the" in scare quotes since, of course, there are often multiple cycles in time series data. 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. find a blog page that provides all of the information i 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. 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. Your email address will not be published. Never heard these before. Gain Control Range: 80 dB. Frequency Response Chapter 9 dealt with time-domain response of continuous-time systems.

If … ‰³- endstream endobj 50 0 obj <> endobj 51 0 obj <>stream A frequency response function can be formed from either measured data or analytical functions. If you start out with something like G(s) = (s +ω n), then factor as G(s) = ω n * s ω n +1 +. 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.

Lower Frequency Response: 38 Hz at -6 dB in room. H‰\“Ën£@E÷|E/“EÄ«»*HÈ’c'’“Dã™ÀĞö �µñÂ? 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. 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. The T-Zero didn’t slow the bass down at all, proving easily able to keep up with the speakers in terms of timing. 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 cleaner midrange and better overall bass quality came as no surprise, because I’ve indulged in this experiment before. REL’s subwoofer isn’t for the big boomers, but will subtly augment the sound of systems in smaller rooms, writes Ashley Kramer. Tel: +44 (0)1656 768777 4.9.

Entertainment for Grownups – Hi-Fi, Home Theatre, Music, Movies, TV & Film, Gaming, Gadgets and more! Lo and behold, exactly as promised by the Viganoni theory, the midrange was clearer and the bass seemed slightly more articulate. 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. Learn how your comment data is processed. Thanks for teh great review. The frequency is "the" period at which seasonal cycles repeat.
