Little Diamond
805 D4 might be smaller than its tower speaker siblings, but it’s no lightweight: its beautifully constructed Reverse-Wrap cabinet, stiff aluminum bass pods and 165mm (6.5-in) Continuum™ mid-bass cone afford it exceptional bass extension and scale for a relatively compact speaker.

Diamond dome tweeter
One of B&w's most significant accomplishments over the past two decades, the ultra-stiff, supremely accurate Diamond dome tweeter is the perfect combination of low mass, exceptional stiffness and outstanding accuracy. 15 years after B&w introduced it, we haven’t found a better tweeter dome technology.

Solid Body Tweeter assembly
Bowers & Wilkins newest 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. The carefully decoupled housing is milled from a single solid block of aluminum to better resist resonance.

Rear-mounted crossover
The new reverse-wrap orientation of the cabinet on 805 D4 means B&w were able to place its sensitive crossover components inside their own, dedicated space within the cabinet, which has critical benefits to both performance and serviceability. B&w have taken the opportunity to upgrade the speaker terminals, too.

The science of sound
Innovation is at the heart of everything B&w do. They question, examine, understand and then evolve. Bowers & Wilkins use computer modelling to explore and reimagine every aspect of loudspeaker design.
