BOWERS & WILKINS 805 D4, ANT STOVO PASTATOMA GARSO KOLONĖLĖ

Diamond dome tweeter

One of our 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 we introduced it, we haven’t found a better tweeter dome technology.

Our 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 aluminium to better resist resonance.

The new reverse-wrap orientation of the cabinet on 805 D4 means we can place its sensitive crossover components inside their own, dedicated space within the cabinet, which has critical benefits to both performance and serviceability. We’ve taken the opportunity to upgrade the speaker terminals, too.
