The R400b subwoofer continues with the modern, polished external styling of the rest of the R series speaker range and also incorporates a brushed aluminium trim - this all combines to make it one of the most stylish looking subs I have seen pass through our showroom in the last decade. KEF also understand that nowadays the look of a product in your room can be as important as the sound. The R400b is incredibly compact so it fits into your room in a classy, elegant way - measuring a room friendly 365x330x351 mm it is easy to fit into any home theatre or Hi-Fi system without being a huge, ugly black box that dominates the room. Internally the R400b consists of a reinforced and solidly braced cabinet that houses two active opposed custom KEF 9” drivers. This set up is done so that both driver outputs cancel each other inside the cabinet thus minimizing vibration and consequently the muddy sound that uncontrolled vibration brings. Each of the custom KEF drivers are powered by a 250W internal digital amplifier - making for a total of 500W of power amplification built in to ensure low distortion and clean, accurate, fast bass across all practical volume ranges. On the rear of the R400b sub there is not only your usual gain/volume and frequency click detent dials, but also with a rather unique 3 position Bass boost switch - this is at a very deep bass frequency of around 40Hz - this helps to ensure that you can tune the subwoofer into your room to make sure that you not only hear, but actually feel the lowest of low notes. This is, of course, the whole point of putting a subwoofer into your system. Pictures:
