Description
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.
Aluminium bass pods,
803 D4 mounts two Aerofoil bass cones in aluminium bass pods, each of which is clamed into an internal aluminium plate fixed to the stiffest part of its cabinet. Formed as single pieces of metal,these structres provide theperfect location for clean, acurate bass
