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. Post was not sent - check your email addresses! 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. I would say it lacks the punch and precision of larger subs for movies, but for music I never think about it. If you start out with something like G(s) = (s +ω n), then factor as G(s) = ω n * s ω n +1 +. 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 midrange benefits vanished as expected, but what was surprising was just how easy it was to get the REL to integrate with the system. 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. I have a fact-finding project. 36 Bewertungen Lieferzeit 2-7 Werktage . Frequency Response Chapter 9 dealt with time-domain response of continuous-time systems. Input Connectors: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. Weight: 6.8kg. Sorry, your blog cannot share posts by email. 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. 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. Glad I read this review it sounds great, they are such a powerful little subwoofer! 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. 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. It’s easy and painless! 'Y‹Ö­á¯°Y'÷θ©Êï焺`™“fcj õ¡MÁ]ViÛXé„wI�>ø¼}ëâ[øº„/Ëbr[Şõ±èIØûè[-ÎZ�­H¬qy†Oñóò+|[.ÏŒ9Cjí(UıL»ßê‚Úg{™ÆœœÑç{¼•ı´jíE"�ËãU+pµ ùaã?

URL: rel.net. 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. When it comes to hooking up the T-Zero, users will find that REL takes a different approach to many subwoofer manufacturers. Page 11 REL Set-Up Made Simple REL products are not traditional subwoofers, but are true Sub-Bass Systems. Lower Frequency Response: 38 Hz at -6 dB in room. Weight: 6.8kg.

Just bought two of these to match my B&W 685 s2. A frequency response function can be formed from either measured data or analytical functions. The cleaner midrange and better overall bass quality came as no surprise, because I’ve indulged in this experiment before. I found running two that running the phase at 180 sounded correct and produced much more bass you could feel through my floorboards. 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). Finish: Black or White Lacquer. Okay, here's my question. Entertainment for Grownups – Hi-Fi, Home Theatre, Music, Movies, TV & Film, Gaming, Gadgets and more! always thought the bottom end lacked some punch although the mid and highs are very sweet. This is the range from 50 to 90 Hz. 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. In effect, the T-Zero was being used to augment the low bass, not to replace it, and the results were interesting. REL T-ZERO Subwoofer . Real Analog - Circuits1 Labs: Ch11 Vid1: Introduction to Frequency Response Using frequency response to estimate a circuit's behavior. Gain Control Range: 80 dB. 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. 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. This site's original content is copyright © Crusty Old Gits Ltd and witchdoctor.co.nz. 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. 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. 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. 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. If … If you want a small extension to the bass response of a system like this you could certainly do worse than this little job. 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. Okay, so this is its pseudo-period, pseudo-frequency, pseudo-circular frequency, but that's hopeless. 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. Schutzsystem. The concept of frequency response is again motivated by applying a single sinusoid. Fully Electronic with SET-SAFE All of our designs are true Sub-Bass Systems, meaning they are designed to reproduce I don't think pseudo is a word all by itself, not even in 18.03, circular. 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. end. 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. A frequency response function expresses the structural response to an applied force as a function of frequency. They may also be represented in terms of magnitude and phase. Save my name, email, and website in this browser for the next time I comment. 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. The frequency is "the" period at which seasonal cycles repeat. 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.
