Product Information

Excellence. Evolved.

This is not just another speaker range. Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins. This is their benchmark, their icon; the most advanced range of loudspeakers they know how to make. For Bowers & Wilkins, the 800 Series Diamond is everything they know, and everything they are.

The most compact-headed model brings all of the technical advantages of a dedicated midrange enclosure to a smaller footprint that's easily accommodated in any home. Small doesn't mean compromised, either; 803 D4 still bristles with technical innovation throughout. 


  • Diamond tweeter

  • Continuum cone FST™
  • Anti-Resonance plug
  • Biomimetic Suspension

Biomimetic Suspension

The all-new Biomimetic Suspension revolutionizes midrange cone performance by greatly reducing the unwanted air pressure and coloration that a conventional fabric spider can generate. The result? Midrange transparency you wouldn't believe possible.

Aluminum Bass Pods

803 D4 mounts two Aerofoil bass cones in aluminum bass pods, each of which is clamped into an internal aluminum plate fixed to the stiffest part of its cabinet. Formed as single pieces of metal, these structures provide the perfect location for clean, accurate bass.
