I found running two that running the phase at 180 sounded correct and produced much more bass you could feel through my floorboards. Sorry, your blog cannot share posts by email. All of our designs are true Sub-Bass Systems, meaning they are designed to reproduce 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. 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. end. 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. 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 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.

Tel: +44 (0)1656 768777 Amplifier: 100W Class D. Dimensions (W×H×D): 216 ×241 ×260 mm. This is the range from 50 to 90 Hz. This paragraph will assist the internet visitors for creating new weblog or even a blog from start to The cleaner midrange and better overall bass quality came as no surprise, because I’ve indulged in this experiment before. 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. 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. 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. 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 They would be laking for my needs a little. I don't think pseudo is a word all by itself, not even in 18.03, circular. In a word – impressive. Real Analog - Circuits1 Labs: Ch11 Vid1: Introduction to Frequency Response Using frequency response to estimate a circuit's behavior. REL T-Zero << Previous Next >> Click to enlarge : Details . Your email address will not be published. The gloss surface is gorgeous! 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. Real Imag ω = 50 ⇒ Y X = 0.89∠−27 ...

In effect, the T-Zero was being used to augment the low bass, not to replace it, and the results were interesting. Schutzsystem. 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. T ZERO Sub-Bass System Many or most loudspeakers emphasize the mid-bass. My question is about the 'overlap' between the quads and the REL. Tel: +44 (0)1656 768777 A frequency response function expresses the structural response to an applied force as a function of frequency. A few years back, I bought an Audio Pro sub at a liquidation sale. And its diminutive scale allows it to all-but-hide among the … 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. Description. If you want a small extension to the bass response of a system like this you could certainly do worse than this little job. 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. 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. Lower Frequency Response: 38 Hz at -6 dB in room. The example below finds the 256-point frequency response for a 12th-order Chebyshev Type I filter. Save my name, email, and website in this browser for the next time I comment. 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. Thanks for teh great review. Okay, here's my question. Weight: 6.8kg. 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. 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. – Correlation between frequency and transient responses is indirect, except for 2nd-order systems. 36 Bewertungen Lieferzeit 2-7 Werktage . 4.9. I have a fact-finding project. Finish: Black or White Lacquer. Amplifier: 100W Class D. Dimensions (WxHxD): 216 x 241 x 260 mm. 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. 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. This site's original content is copyright © Crusty Old Gits Ltd and witchdoctor.co.nz. The response may be given in … The frequency response of continuous-time systems gives another view, just as it did for discrete-time systems in Chapter 6. – Frequency-response tests are, in general, simple and can be made accurately by readily-available equipment, e.g., dynamic signal analyzer. The Rel T Zero is small, discrete, and beautiful. If … 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. 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. Price: £350 (per subwoofer) Manufactured by: REL Ltd. URL: rel.net. 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. Power Output: 100 Watts (RMS) Phase Switch: Yes, 0 or 180 degrees. always thought the bottom end lacked some punch although the mid and highs are very sweet. I use "the" in scare quotes since, of course, there are often multiple cycles in time series data. 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. 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. Ähnlich wie die FFT-Analyse ist FRF typisch für ein System, welches eine von einem bekannten Eingangssignal gemessene Rückmeldung hat. Going for a higher end model would be my choice though. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. H‰\“Ën£@E÷|E/“EÄ«»*HÈ’c'’“Dã™ÀĞö �µñÂ? 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 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. 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. The concept of frequency response is again motivated by applying a single sinusoid. It’s easy and painless! They may also be represented in terms of magnitude and phase.
