Our most compact headed model brings all of the technical advantages of a dedicated midrange enclosure ro a smllaer footprint thats easily accommodated in any home. Small doesnt mean compromised, either: 803 D4 still bristles with technical innovation throughout

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

Biometric suspension
Our all-new Biometric suspension revolutionises midrange cone performance by greatlyreducing the unwanted air pressure and coloration that a conventional fabric spdier can generate. The result? Midrange transparencyyou wouldnt believe possible.
