Description 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.
