kef subwoofer review

Yes, I’ve seen EQ mode controls that offer two or three modes, (usually ‘Off’, ‘Wall’ and ‘Corner’) but I have never seen one that offers five modes… and I had absolutely no idea what the ‘Apartment’ mode might be used for – indeed I had to consult KEF’s Owners’ Manual to find out. Many subwoofers that appear to have two – or more – drivers have only one of those drivers connected to an amplifier: the other so-called ‘drivers’ are not drivers at all, but simply ‘drone’ cones or passive radiators that contribute very little to the main output of the subwoofer. Setting up a subwoofer is equal parts simple and complex. The first of my ‘deep-bass’ CDs I fired up was Telarc’s Bachbusters (CD80123). Founded in April 2006, High-Def Digest is the ultimate guide for High-Def enthusiasts who demand only the best that money can buy. Now I heard a difference. With this track, the KUBE 12b pressurized my whole home. KEF uses two drivers for several very important reasons. Using this ‘single amplifier per driver’ approach as KEF has done with its KF92 means that the electromotive forces (EMF) generated by one driver cannot affect the other, or vice versa. It was as if I were listening to a pair of huge, floor-standing loudspeakers. Getting very loud, very low-frequency, distortion-free bass from a subwoofer is very easy. I'd also love to see KEF design an optional (or integrated) wireless system. If the hum persists, moving the switch on ‘On’ should reduce or eliminate it. The other low-frequency sound effects? This is because the unwanted vibrational forces created by the drivers are equal to each other but also exactly opposite in phase to each other, so they cancel out. This means that had KEF wanted to move the same amount of air with a single cone, rather than with two, it would have had to have had a Thiele/Small diameter 247mm, which would have translated to a specified diameter of 332mm. Finally (but far from least, depending on where in the world you live) small furry (or non-furry) ‘critters’ cannot decide the inside of your subwoofer would make a very warm and comfortable home to which they could gain access via the bass reflex port. As expected, the ‘Room’ EQ mode – which assumes the subwoofer is not getting any assistance from nearby walls – delivers the maximum output at low frequencies (black trace). It simply oozes quality. Lastly, I tuned the system with the AVR's Audyssey calibration and manually bumped the volume up a few clicks. Two absolutely identical emitters, the baskets of which are rigidly interconnected, are mounted in completely closed 22-litre body. Nevertheless, it has all the information you need to install the subwoofer, correctly position it in your room, and connect it to another subwoofer (if required) a pair of KEF powered speakers (such as the LS50S/LSK) or a pair of small unpowered speakers via a separate amplifier. The connections and switches are quick and plug-n-play. This new sub is a sleeper; relatively compact and subtly designed, but it absolutely roars, pressurizing your room with elegantly-deep bass. You should start with it in the Off position and, if you hear any hum, first check and re-arrange all your cables and check mains earths. I have heard KEF subwoofers previously, and I’ve always been impressed by them. This review and test originally appeared in Australian Hi-Fi magazine, one of What Hi-Fi?’s sister titles from Down Under. The sound of the organ pipes was full, rich and textural and pitch differences were immediately evident, just as they should be. By Stephen Dawson. For connection to a preamp or similar, you’d use both terminals. Cyber Monday deals: see all the best offers right now! Not that subwoofer manufacturers haven’t tried… and KEF has tried harder than most. KUBE 12b ($699.99 each). All the low bass was still present, and still perfectly reproduced. Visually, the new KUBE subwoofers are compact cubes with a glossy black top and sides wrapped in a flat, black cloth. In terms of missing features, I'd love to see KEF offer a wireless kit for this series (or possibly even as a built-in feature), which would expand and extend room-placement possibilities. The very high power of the two 500-watt amplifiers is evidenced by the expanse of the heat-sinking, though most of this is obscured by an artfully contrived silky-smooth cover plate. However, to inject some reality into this comment, I was listening at very high volume levels in a very large room. The bass was awesome! Wrote My Way Out, from The Hamilton Mixtape, might be the perfect Q950/KUBE 12b demo, blending warm mid-tone hook vocals, crisp piano chords, and a chest-thumping beat. is part of Future plc, an international media group and leading digital publisher. Buttery. Jumping from hip-hop to metal, Black Sabbath's 13 is a monster album that might be the group's heaviest in terms of production and design. So I flicked the switch. The black and red traces on Graph 5 are identical to those on Graph 1, but Newport Test Labs has extended the frequency range covered by the graph to allow it to add in the frequency response via the LFE input (green trace) measured using the same acquisition technique. To avoid disturbing neighbours, set the EQ to ‘Apartment Mode’ to reduce the level of very low frequencies (below 40Hz).’ I can see how this would be very useful for apartment dwellers… even though it does kind of defeat the purpose for buying a subwoofer in the first place. , Stephen Dawson looks at one from a subwoofer is equal parts and.
