The 801 D4 Signature floor-standing speaker features optimised technologies, including that all-important Diamond Dome tweeter and Solid Body Tweeter-on-Top, an all-new tweeter grille, and upgraded crossover.

801 D4 Signature

Our flagship loudspeaker optimised for perfection.

Optimised for perfection

The 801 D4 Signature is an optimised version of our most advanced loudspeaker. It features meticulously evolved technology, carefully crafted design, and unique finishes that culminate in the pinnacle of performance. This is Bowers & Wilkins' flagship loudspeaker perfected.

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. Fifteen years after we introduced it, we haven't found a better tweeter dome technology.

Solid Body Tweeter

Our Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system and an all-new design of tweeter grille, producing an even more free and open sound with high frequencies.

Upgraded crossover

Our 801 D4 Signature uses upgraded rear-mounted crossover designs mounted on stiff aluminum 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.

Aluminum top-plate

Every new 800 Series Signature model has a significantly upgraded cabinet design with an all-new, optimised aluminum top section for even greater stiffness. The same design also provides a perfect mounting point for Leather by Connolly cabinet detailing, with luxurious full-grain blue leather for our Midnight Blue Metallic models and full-grain black leather for our California Burl Gloss models.
