KEF Q400b Subwoofer

KEF Q400b Subwoofer

The multiple award-winning Q Series has always exemplified KEF’s conviction that new materials and technologies can, when applied with intelligence and imagination, reproduce recordings so perfectly that they sound indistinguishable from the live event. This is more true now than ever before. As the latest expression of this design philosophy, the new range immerses you in three-dimensional imagery of a richness and clarity that until now has been the exclusive preserve of speakers costing many times more.

Product detail

The final ingredient of your new Q system is of course the seductive Q400b subwoofer. A closed box design housing a 250mm (10in.) woofer driven by a 200W on-board Class-D amplifier, this discreet cube creates spectacular bass imagery – eloquent, musical and addictively physical. Anchoring the whole sound performance in an all-embracing sensation of immediacy, it completes the acoustic picture.
