KEF R400b Subwoofer

KEF R400b Subwoofer

The R400b subwoofer is the final step to achieving a truly immersive home cinema audio experience at an accessible price. The R400b is simply seductive, offering a superlative performance of liquid-like bass, complete with the same level of control and sophistication that one would expect from any product made from KEF. Its cabinet is just 31 inches square, meaning that this punchy and dynamically capable subwoofer is not only pleasing to the ears but also aesthetically, offering a non-obtrusive option that's easily integrated with existing decor.

The R400b's twin 9-inch LF drivers are powered by two dedicated 250 Class-D amplifiers, housed within a reinforced and braced sealed cabinet. The drivers of the R400b are mounted back to back from each other, this arrangement forms what KEF call a 'force cancelling' system, resulting in the opposing reactive forces to be invalidated, completely eradicating cabinet agitation and drastically reducing unwanted resonance. This unit is designed to match the other models within the R series flawlessly and adds a new depth of dynamic superiority to what is already a superb set of loudspeakers.
