Regallautsprecher 805 D4

This is not just another speaker range. Each new generation of 800 Series Diamond is a landmark event for Bowers & 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.

Our iconic Solid Body Tweeter-on-Top housing features an elongated form 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 block of aluminium to better resist resonance.

Compared to 805 D3, the new 805 D4 introduces an all-new reverse-wrap cabinet design with an upgraded plywood Matrix bracing plus extensive use of aluminium in critical areas. Its rear-mounted crossover is isolated from the cabinet and the new, extended Solid Body Tweeter assembly features an enhanced two-point decoupling system for even more spaciousness

The latest incarnation of our iconic Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system, producing 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.

Hear the sound, not the cabinet. We’ve used separate midrange enclosures on 800 Series models from the very beginning: now, our all-aluminium Turbine Head housing takes the concept to the next level. This phenomenally stiff and inert housing for the crucial midrange cone is carefully damped to avoid unwanted resonances and decoupled from both the bass enclosure and the tweeter body. The result? The most realistic midrange sound yet.

All stereo models in the new 800 Series Diamond range now use rear-mounted crossover designs mounted on stiff aluminium spines. This isolates the sensitive capacitors from the unwanted effects of air pressure within the enclosure and makes for a very effective heatsink to ensure optimum performance when in use.
