Bowers & Wilkins B&W 805 D4

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.

Solid Body Tweeter
Our iconic solid body tweeter on top housing features an elongated from with a longer tube loading system, creating an even more free and open sound with high frequencies. As before the carefully decoupled housing is milled from a single solid block of aluminium to better resist resonance.

Rear-mounted crossover
All stereo in the ne range now use rear-mounted crossover designs mounted on stiff alumium spines. This isolates the sensitve capacitors from the effects of air pressure withing the enclosure
