kef subwoofer review

By Stephen Dawson. The first and most obvious of these is that whereas bass reflex ports can sometimes create audible noises – usually ‘chuffing’ sounds, but sometimes whistling sounds – you won’t ever get these noises with the KEF KF92 because there is no port. What Hi-Fi? I played one track after another. It's refined. Updated daily and in real-time, we track all high-def disc news and release dates, and review the latest disc titles. Another advantage is that because the cabinet is sealed, all the internal metal components are protected from corrosion, which can be a problem in hot, humid environments. All rights reserved. The most obvious (but wrong!) Founded in April 2006, High-Def Digest is the ultimate guide for High-Def enthusiasts who demand only the best that money can buy. The connections and switches are quick and plug-n-play. UK speaker builder Kef has a great reputation in the hi-fi field. Bringing you all the best reviews of high definition entertainment. ‘Corner’ EQ (green trace) drops output at low frequencies by a further 6dB, while ‘Cabinet’ EQ drops it by yet another 6dB. I don’t think I’ve seen its like before. Below the two rotary controls are four slider switches that control (from left to right), Crossover Mode (Internal or External), Equalisation mode (Room, Wall, Corner, Cabinet and Apartment), Phase (0°/180°), and Ground Lift (On/Off). With a 12" (300mm) driver and a maximum output of 114dB, the KUBE 12b boasts a 22Hz - 140Hz frequency response range, measures 16.1" tall by 15.5" wide by by 16.1" deep, and weighs 45.4lbs (20.6kg). This new sub is a sleeper; relatively compact and subtly designed, but it absolutely roars, pressurizing your room with elegantly-deep bass. While there are some very minor gripes about its controls and connectivity, the K92 from KEF brings some of the cleanest, deepest sub frequencies on offer, and does so in a charmingly compact enclosure. KUBE 8b ($499.99 each). The available turnover frequencies for this filter are at 40Hz, 45Hz, 50Hz, 55Hz, 60Hz, 70Hz, 80Hz, 90Hz, 100Hz, 110Hz and 120Hz. It simply oozes quality. All these EQ modes have roughly similar equalisation curves, with the turnover for all taking place at around 70Hz. There’s a small tell-tale dual-colour LED above the switch that glows red when the subwoofer is off but power is available, and glows green when it’s operational. KUBE 10b ($599.99 each). KEF’s equalisation mode control is fascinating. Zowel een 'muziek' stand (strakkere bas) als 'cinema' stand (meer aanwezig, zoals ook gewenst). You will receive a verification email shortly. The ‘pulse’ is incredible… you’ll feel it echoed in your own body. 08/03/2018. All rights reserved. Effectively, it was in line with a Q650c Center Channel but in front of my entertainment center shelving. KUBE 12b ($699.99 each). 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. Both are high-quality stepped devices, so you can set frequency and level very easily and precisely and just as easily re-set them to the same exact levels if the settings are for any reason disturbed. Likewise, Mad Max Fury Road and Pacific Rim boast two of the best  LFE-heavy Dolby Atmos mixes ever released; Fury Road revels in symphonies of guttural engines while Pacific Rim literally roars with screaming monsters and weaponized robots. Luckily, KEF provides three different in-sub DSP calibrations -- Corner, In-Room, or Wall/Cabinet -- to help tune the sub to its location and this works pretty well too. Alas, that is not the case—only black. In that sense, my KUBE 12b komplaints are minor when compared to my enthusiasm. If it’s from a component that is supplying an audio signal that has already been through a low-pass filter (such as the LFE output of an AV receiver, for example) you’d set this control to ‘External’. In order to ensure that one of its smallest-ever subwoofers could deliver deep bass it even invented an innovative circuit it called ‘Intelligent Bass Extension’ or IBx for short. Overview -- Save for the stunning-yet-pricey R400b (review HERE), I don't usually look to KEF for subwoofers -- my old PSW2500 suffered from overheating and the Q400b was far too tame -- but all of that changes with the KEF KUBE 12b. England and Wales company registration number 2008885. I know this is a big call in a crowded market, but I’d say KEF’s K92 may be the best small subwoofer of them all. It measures 353 x 330 x 361mm (HxWxD) and weighs 20kg. KEF’s EQ settings adjust its output to ensure the KF92 will deliver its best performance no matter where in the room you end up putting it… even if you put it inside a cabinet. I'd also love to see KEF design an optional (or integrated) wireless system. 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.

Below the LFE/line-level inputs is a pair of line-level outputs. Not that subwoofer manufacturers haven’t tried… and KEF has tried harder than most. The first of these is the ability to send audio signals to the KEF K92 wirelessly, which will be enabled via a separately available wireless kit (KW-1). Sure, you can find other subs with MORE earth-shattering, heart-stopping bass, but you're going to spend more money and it'll weigh a lot more. Newport Test Labs first measured the frequency response of the KEF KF92 in a room, using pink noise as the test stimulus, with the EQ setting set to ‘Room’, the result of which is shown in Graph 1. So I flicked the switch. Perhaps the most important of these is that the thousand watts of amplifier power that KEF provides is far too high for a single driver’s voice-coil to dissipate. Setting up a subwoofer is equal parts simple and complex. KEF uses two drivers for several very important reasons.
