801 D4 Signature

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

One of the 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 Bowers introduced it, they have yet to find a better tweeter dome technology.

The 801 D4 Signature uses upgraded 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.

Every new 800 Series Signature model has a significantly upgraded cabinet design with an all-new, optimised aluminium 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 the Midnight Blue Metallic models and full-grain black leather for the California Burl Gloss models.

Bowers & Wilkins

Bowers & Wilkins (B&W) is now a very large company, with distribution chains and customers all over the world. However it began in 1966 with John Bowers hand-assembling speaker systems for local clients in Worthing, West Sussex, in the back of the electrical store that he ran with his friend Roy Wilkins.

Five decades later the company is a global leader in sound, and in 2016 Bowers & Wilkins were incredibly proud to celebrate their 50th anniversary – and even more proud that the ethos, passion and drive of its founder is still a vital element in its continuing success.
