Product Information

Crafted. Honed. Perfected.

The 801 D4 Signature is an optimized version of Bowers and Wilkins 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 800 Series Signature flagship loudspeaker.

Turbine Head

Hear the sound, not the cabinet. Bowers and Wilkins' all-aluminum Turbine Head is a phenomenally stiff and inert housing for the crucial midrange cone, carefully damped to avoid unwanted resonances and decoupled from both the bass enclosure and the tweeter body. The result? The most realistic midrange sound yet.

Solid Body Tweeter

The latest incarnation of Bowers and Wilkins' iconic Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system and an all-new design of tweeter grille that has been optimized to produce an even more free and open sound with high frequencies. As before, the carefully decoupled housing is milled from a single solid block of aluminum to better resist resonance.

Reverse Wrap Cabinet

Instead of a flat-fronted speaker with a curving back, Bowers and Wilkins' cabinets are formed from one continuous curve, finished off with a spine of solid aluminum. Fewer joins make for a stiffer, more inert structure, and a curved front means less baffling around the drive units. So sound dispersion is improved, and cabinet reflection is reduced.


Matrix™ bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage. Both the new 800 Series Signature models benefit from Bowers and Wilkins' most advanced Matrix design that combines solid plywood construction with aluminum bracing to reinforce key stress points.

Biomimetic Suspension

They have turned their attention to another crucial element in a loudspeaker cone: the fabric spider. Bowers and Wilkins' advanced Biomimetic Suspension revolutionizes midrange cone performance by greatly reducing the unwanted air pressure and coloration that a conventional fabric spider can generate. The result? Midrange transparency you wouldn’t believe possible.

Aluminum top-plate

Every new 800 Series Signature model has a significantly upgraded cabinet design with an all-new, optimized aluminum top section for even greater stiffness. The same design also provides a perfect mounting point for all-new 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.


Both new 800 Series Signature models use 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.

Leather by Connolly

The top section of both speakers features an optimized aluminum top-plate, covered in all-new Leather by Connolly trim. Bowers and Wilkins use luxurious, full-grain blue leather for Midnight Blue Metallic, and full-grain black leather for California Burl Gloss.
