Bowers & Wilkins 804 D4 Floorstanding Speaker

Description

804 D4

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 the best-performing 804 yet.

804 D4 is perhaps more conventional in appearance than other floor-standers in the 800 Series Diamond range, but it is 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.

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.

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.

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.

Bowers & Wilkins

Bowers & Wilkins (B&W) is now a very large company, with distribution chains and customers all over the world. However it began in 1966 with John Bowers hand-assembling speaker systems for local clients in Worthing, West Sussex, in the back of the electrical store that he ran with his friend Roy Wilkins.

Five decades later the company is a global leader in sound, and in 2016 Bowers & Wilkins were incredibly proud to celebrate their 50th anniversary – and even more proud that the ethos, passion and drive of its founder is still a vital element in its continuing success.
