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. 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. 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. 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. 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. Description. The company is into good subwoofers, the kind that are intended to make music, not go boom. And its diminutive scale allows it to all-but-hide among the … Input Impedance: High-Level: 150k, Low Level: 10k, .1/LFE: 10k ohms. In fact, the very comprehensive manual states: “ALWAYS connect using the REL HIGH-LEVEL input, unless your system simply cannot accommodate this”. 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 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 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 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. Power Output: 100 Watts (RMS) Phase Switch: Yes, 0 or 180 degrees. Tel: +44 (0)1656 768777 But your review makes me think they may be worth a shot. My question is about the 'overlap' between the quads and the REL. 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.

Going for a higher end model would be my choice though. without breaking the bank, a REL T-Zero V2 (or preferably, two) can’t be beaten. Schutzsystem. A frequency response function can be formed from either measured data or analytical functions. 36 Bewertungen Lieferzeit 2-7 Werktage . Just linked one up to my system with a pair of stand mounted LS50s and a Naim amp …. Gain Control Range: 80 dB. 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. end. The Frequency Response Function for LTI Systems • The output of an LTI system can be … However, integrating a subwoofer into a stereo system can be a frustrating exercise, especially for owners of floorstanding speakers. 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. Glad I read this review it sounds great, they are such a powerful little subwoofer! In this way, the REL is fed the exact signal that is fed to the main speakers.”. Connections: High-Level Neutrik Speakon, Low-Level single phono, LFE phono. for some time, and it seems to have taken a long time to 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. REL’s subwoofer isn’t for the big boomers, but will subtly augment the sound of systems in smaller rooms, writes Ashley Kramer. They’re totally accepted and even loved in the home theatre environment, but somewhat scorned in stereo environments by much of the audiophile community.
