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.
