Bowers & Wilkins 804 D4
The Bowers & Wilkins 800 Series
This is not just another speaker series. This is the benchmark, the likeness – the most advanced speaker series Bowers & Wilkins can produce.
Bowers & Wilkins 804 D4 Floorstanding Loudspeaker
The new 804 D4 features a downward radiating flowport and a solid aluminum base with a damped steel insert that minimizes unwanted resonances. Extensively improved spikes provide maximum stability.
Inverted design
When it came to designing the ideal shape for the 800 Series Diamond, Bowers & Wilkins did an about-face – literally. The Gehäuse have a continuous curved design that is enhanced by a solid aluminum back, so sound dispersion is improved and reflection of cabinet is reduced.
Classic quality
The 804 D4 may look more ordinary than the other floorstanding speakers in the 800 Series Diamond, but it is in no way inferior to those models. The new inverted cabinet is a revolution in its class, both mechanically and acoustically, while the new base ensures rock-solid, accurate bass response.
Sound with brains
The 804 D4 is the entry-level floorstanding loudspeaker model of the 800 Series Diamond. The 803 D4, on the other hand, features larger bass drivers (180 mm/7 inches) and, most importantly, an attached Turbine™ Head enclosure for the midrange cone (130 mm/5 inches), which adds even more intense spaciousness to the sound.
The Bowers & Wilkins 804 D4 with aluminum base
A great speaker needs a solid foundation. The new 804 D4 features a downward radiating flowport and a solid aluminum base with a damped steel insert that minimizes unwanted resonances. The extensively improved spikes provide maximum stability.
Aluminum cover plate
Each stereo model in the new 800 Series Diamond features a comprehensively optimized cabinet with an all-new aluminum top plate. A fine Connolly leather cover – in sophisticated black for dark Gehäuse, in light gray for lighter finishes – adorns the surfaces.
Our knowledge of sound
Innovation is at the heart of this work. It is questioned, examined, understood and further developed. Using the latest simulation techniques, every detail of the loudspeaker design is examined and revised. Learn more about all the technologies that make the 800 Series Diamond so special.
