B&W 804 D4 Reference Speaker

For listeners who prefer a more conventional aesthetic but crave the performance of an 800 Series Diamond loudspeaker, the 804 D4 is the perfect choice. its new reverse-wrap cabinet follows the proven design principles established by its larger siblings and its new plinth ensures rock-solid, accurate bass response too.

Solid Body Tweeter The latest incarnation of our iconic Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system, producing an even more free and open sound with high frequencies. As before, the carefully decoupled housing is milled from a single block of aluminium to better resist resonance.

Matrix Matrix bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage. Every loudspeaker in the new 800 Series Diamond benefits from an upgraded Matrix design that combines solid plywood construction with aluminium bracing to reinforce key stress points.

Decoupled midrange Every 800 Series Diamond loudspeaker apart from the standmount 805 D4 has a dedicated midrange cone using several proprietary Bowers & Wilkins technologies: the Continuum FST cone, Biometric Suspension and midrange decoupling, the latter ensuring minimal interference in the operation of the loudspeaker's bass units.

Rear-mounted crossover All stereo models in the new 800 Series Diamond range now use rear-mounted crossover designs mounted on still aluminium spines. This isolates the sensitive capacitors from the unwanted effects of air pressure within the enclosure and makes for a very effective heatsink to ensure optimum performance when in use.
