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. Lower Frequency Response: 38 Hz at -6 dB in room.

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 +. 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. Tel: +44 (0)1656 768777 In a word – impressive. I don't think pseudo is a word all by itself, not even in 18.03, circular. 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. Power Output: 100 Watts (RMS) Phase Switch: Yes, 0 or 180 degrees. 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. Page 11 REL Set-Up Made Simple REL products are not traditional subwoofers, but are true Sub-Bass Systems. But your review makes me think they may be worth a shot. 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. Entertainment for Grownups – Hi-Fi, Home Theatre, Music, Movies, TV & Film, Gaming, Gadgets and more! I guess it should be circular pseudo-frequency, or I don't know how you say that. 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 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. Okay, here's my question. 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. ASHLEY KRAMER. 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. Save my name, email, and website in this browser for the next time I comment. Your website has definitely offered me personally with just the facts that I actually required. FRF-Messungen (Frequency Response Function/Übertragungsfunktion) Die gebräuchlichste Übertragungsfunktionsmessung ist die FRF (Frequency Response Function). Bottom end extension is limited (as expected) with REL claiming a modest 38 Hz at -6dB in room. 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. 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. 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. freqz can accept other parameters, such as a sampling frequency or a vector of arbitrary frequency points. The Frequency Response Function for LTI Systems • The output of an LTI system can be … 36 Bewertungen Lieferzeit 2-7 Werktage . 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 Glad I read this review it sounds great, they are such a powerful little subwoofer! Going for a higher end model would be my choice though. In this way, the REL is fed the exact signal that is fed to the main speakers.”. Designed by WPZOOM. If … 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 gloss surface is gorgeous! Vorkasse, Kreditkarte, EPS € 12,-. 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. }¹V" ’ÍAĞUçtºÙmwC?›ô3ŒíŞÏæØ]ğ—ñZoşÔI^˜®oçûÕòß�›)Iãâıí2ûón8�I]›ôg¼y™ÃÍ“ô#t>ôÃÉMº¿NÓ_öÃl2³Z™Îc¡ÍôŞœ½I—eO».ŞïçÛS\óıįÛäM±\ç”iÇÎ_¦¦õ¡N>©³x¬Lı�Uâ‡î¿ûr_v8¶š�ÔβxŠüL~Wä 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.

So REL products are engineered for integration into stereo systems. The company is into good subwoofers, the kind that are intended to make music, not go boom. I actually have recently been undertaking study upon this theme Fully Electronic with SET-SAFE SUBWOOFERS ARE A bit of a conundrum. I found running two that running the phase at 180 sounded correct and produced much more bass you could feel through my floorboards. 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. Amplifier: 100W Class D. Dimensions (W×H×D): 216 ×241 ×260 mm. 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. Okay, so this is its pseudo-period, pseudo-frequency, pseudo-circular frequency, but that's hopeless. Draw the gain term (ω n)separatelyfromthezeroterm(s/ω n +1). Just bought two of these to match my B&W 685 s2. REL T-Zero. 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. Amplifier Type: Class D . (adsbygoogle = window.adsbygoogle || []).push({}); Give a little to support Witchdoctor’s quest to save high quality independent journalism. In effect, the T-Zero was being used to augment the low bass, not to replace it, and the results were interesting.

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). When it comes to hooking up the T-Zero, users will find that REL takes a different approach to many subwoofer manufacturers. find a blog page that provides all of the information i Your email address will not be published.
