REL T-Zero. ’…Å_î“ #Hǘ$¶š ÕŒÛrÇÆâ¿€S| %!æÈ. In a word – impressive. 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. for some time, and it seems to have taken a long time to This site's original content is copyright © Crusty Old Gits Ltd and witchdoctor.co.nz. The cleaner midrange and better overall bass quality came as no surprise, because I’ve indulged in this experiment before. H‰\“Ën£@E÷|E/“EÄ«»*HÈ’c'’“Dã™ÀĞö �µñÂ? Tel: +44 (0)1656 768777 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. Weight: 6.8kg. 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. 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. Glad I read this review it sounds great, they are such a powerful little subwoofer! The company is into good subwoofers, the kind that are intended to make music, not go boom. I use "the" in scare quotes since, of course, there are often multiple cycles in time series data. 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. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. 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. They’re totally accepted and even loved in the home theatre environment, but somewhat scorned in stereo environments by much of the audiophile community. Bottom end extension is limited (as expected) with REL claiming a modest 38 Hz at -6dB in room. 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. It’s easy and painless! All of our designs are true Sub-Bass Systems, meaning they are designed to reproduce Frequency Response Chapter 9 dealt with time-domain response of continuous-time systems. 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. 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. However, the sub integrated with the room better than the speakers do, creating fewer high pressure bass nodes. Power Output: 100 Watts (RMS) Phase Switch: Yes, 0 or 180 degrees. 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. Finish: Black or White Lacquer. 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. Lower Frequency Response: 38 Hz at -6 dB in room. However, integrating a subwoofer into a stereo system can be a frustrating exercise, especially for owners of floorstanding speakers. 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. 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. 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. you down the road, and will take a look right here first of all the very next time Input Connectors: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. Post was not sent - check your email addresses! 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. I would say it lacks the punch and precision of larger subs for movies, but for music I never think about it. Apparently, wanting to repeat this huge success, the company included a miniature T-ZERO in its assortment. Lo and behold, exactly as promised by the Viganoni theory, the midrange was clearer and the bass seemed slightly more articulate. 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 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. They would be laking for my needs a little. The example below finds the 256-point frequency response for a 12th-order Chebyshev Type I filter. Norstone Stylum 2. And its diminutive scale allows it to all-but-hide among the … 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 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 concept of frequency response is again motivated by applying a single sinusoid. Fully Electronic with SET-SAFE Page 11 REL Set-Up Made Simple REL products are not traditional subwoofers, but are true Sub-Bass Systems. 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. 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. Frequency response functions are complex functions, with real and imaginary components.

Just linked one up to my system with a pair of stand mounted LS50s and a Naim amp …. Sorry, your blog cannot share posts by email. 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. The gloss surface is gorgeous! Amplifier: 100W Class D. Dimensions (WxHxD): 216 x 241 x 260 mm. freqz can accept other parameters, such as a sampling frequency or a vector of arbitrary frequency points. Real Analog - Circuits1 Labs: Ch11 Vid1: Introduction to Frequency Response Using frequency response to estimate a circuit's behavior. 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.
