Bowers & Wilkins 804 D4 Floorstanding Speakers

804 D4 floorstanding speaker

For listeners who crave the performance of an 800 Series Diamond™ floorstander but prefer a more conventional aesthetic, the 804 D4 is the perfect choice. Its new cabinet and plinth make it Bowers & Wilkins best-performing 804 yet.

Classic quality

804 D4 is perhaps more conventional in appearance than other floorstanders 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, and its new plinth ensures rock-solid, accurate bass response too.

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. It also has greatly upgraded spikes for maximum stability and durability.

The science of sound

Innovation is at the heart of everything Bowers & Wilkins do. They question, they examine, they understand and then evolve. Bowers & Wilkins use computer modelling to explore and reimagine every aspect of loudspeaker design.

Get a Head

804 D4 is the entry-level floorstanding model in the 800 Series Diamond range. Step up to 803 D4 and you’ll find larger bass drivers (180mm, 7in) plus, crucially, the addition of a Turbine™ Head enclosure for the 130mm (5in) midrange cone, which adds even more spaciousness to the sound.

Decades in the making

John Bowers wanted the original Model 801 to clearly be superior to anything he had done before: to be the best loudspeaker the world had ever heard. Over the decades that have followed, Bowers & Wilkins constantly evolved his original design, but his passion for perfection continues to inspire Bowers & Wilkins to this day.
