The Bowers & Wilkins 804 D4 is the smaller floor-standing model in the 800 Series Diamond range.

With a more conventional aesthetic, the 804 D4 is the perfect choice if you want the performance of the 800 Series Diamond™ with a smaller footprint. Its new cabinet and plinth make it our best-performing 804 yet.

Classic quality

The 804 D4 is more conventional in appearance than other floor-standers in the 800 Series Diamond range, but it’s every bit as sophisticated. Its new Reverse-Wrap cabinet is both a mechanical and acoustic revolution in its class, with a downwards-firing Flowport its new plinth ensures rock-solid, accurate bass response too.

Diamond DomeTweeter

The Solid Body Tweeter-on-Top has been revised in every new 800 Series Diamond loudspeaker, including both models with and without the Turbine Head. The new design is longer – approaching 30cm (12-in) long – and its longer tube length has notable benefits for the resonant frequency (f/s) of the diamond dome tweeter, essentially meaning that the dome can now ‘breathe’ more easily than before. Alongside a revised two-point decoupling mechanism that ensures better-than-ever isolation of the sensitive assembly from its surrounding enclosure, the result is an even-more-believable sense of sounds floating in free space rather than being restricted to the confines of a loudspeaker cabinet.

Aluminium top-plate

Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet with an all-new aluminium top-plate. This also provides a perfect mounting point for all-new Leather by Connolly trim, with luxurious black leather for dark cabinets and light grey for lighter finishes.

Reverse Wrap cabinet

Instead of a conventional loudspeaker box, the cabinet in 804 D4 is made from a continuous curved section of wood, with the drive units mounted at the heart of the curvature. This stiffer, more inert structure resists mechanical resonances far better and also ensures better dispersion of sound.

Aluminium plinth

A great speaker needs a rock-solid foundation. The new 804 D4 uses a downwards-firing Flowport exiting on to a solid aluminium plinth complete with a steel constrained layer damping sheet, which controls unwanted resonance. additional massively thicker M12 floor spikes replacing the older M6 designs has greatly upgraded stability and durability.

All of this work has gone into just acoustic and mechanical properties of each loudspeaker – we haven’t even scratched the surface of transducer design or crossover componentry. But even with ‘just’ this area covered, it should be clear that the results are radically transformed loudspeakers that sound even more believable – and even less like loudspeakers – than ever.
