Bowers & Wilkins 804 D4 Tower Speaker

The Bowers & Wilkins 804 D4 Tower Speaker is perhaps a more conventional in appearance than the other tower speakers 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.

The 804 D4 is a significant upgrade over its predecessor. Purity, resolution and prominently presenting the finest detail and a lifelike performance are its strengths.” – 5 stars



  • Tight, detailed, punchy, musical sound
  • Highly accurate soundstaging
  • Reverse wrap design looks great
Aluminum top-plate

Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet with an all-new aluminum 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.

Aluminum plinth

A great speaker needs a rock-solid foundation. The new 804 D4 uses a downwards-firing Flowport exiting on to a solid aluminum 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 they do. They question, examine, understand and then evolve. They use computer modelling to explore and reimagine every aspect of loudspeaker design.

Step Up

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