801 D4 SIGNATURE*

Enceinte en colonne

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.

The loudspeaker that sets the standard all high-end designs will be judged by for years to come. Endowed with every new technology the 800 Series Diamond has to offer, the 801 D4 also marks the return to our portfolio of one of our most iconic model names.

Our all-aluminium Turbine Head is a phenomenally stiff and inert housing for the crucial midrange cone, 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.

Every model in the new 800 Series Diamond benefits from an upgraded Matrixdesign. Aluminium reinforced interlocking panels brace the speaker's cabinet walls in all directions, reducing resonance and creating a more believable soundstage.
