The 804 D4 is an excellent choice for those who don't want to sacrifice the performance of a Bowers & Wilkins 800 Series Diamond™ floorstanding speaker, but prefer a more traditional shape. Thanks to the new cabinet and base, the 804 now delivers more power than ever before.

Classic Quality
The 804 D4 may look more ordinary than the other 800 Series Diamond floorstanding speakers, but it's no less than those models. The new inverted cabinet is a revolution in its class, both acoustically and mechanically, while the new base delivers rock-solid, accurate bass response. 

Aluminium top plate
 All stereo models in the new 800 Series Diamond feature a comprehensively optimised cabinet with an all-new aluminium top plate. A fine Connolly leather cover - in black for dark cabinets, in light grey for lighter finishes - adorns the surfaces.

Inverted design
Instead of a conventional speaker shape, the 804 D4's cabinet features a continuous rounded wooden front, with the driver units located in the centre. This stiffer, acoustically more neutral structure counteracts mechanical resonances much better and therefore has a positive effect on sound dispersion.

Aluminium base
A great floorstanding speaker needs a solid foundation. The new Bowers & Wilkins 804 D4 features a downward-firing flowport and a solid aluminium base with damped steel insert to minimise unwanted resonance. Enhanced spikes ensure maximum stability and durability.

Bowers & Wilkins Knowledge of Sound
Innovation is at the heart of Bowers&Wilkins' work. They question, investigate, understand and then develop. Using advanced simulation techniques, Bowers & Wilkins investigate and rework every detail of loudspeaker design.

One of the best from Bowers & Wilkins
The 802 D4 is a very special speaker - an exciting blend of style and performance that is second to none. It's topped only by one model in our range: the flagship 801 D4, with 250mm bass cones in a larger, solid bass cabinet.
