Bowers & Wilkins 805 D4 Signature Stand-Mount Speaker (Pair)

Turbine Head
Hear the sound, not the cabinet. Bowers & 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.

Biomimetic Suspension
Sometimes, making a big difference takes unconventional thinking. For decades, we thought nothing could improve on the sound of our famous yellow Aramid Fiber midrange cones, but eventually, our Continuum™ Cone technology changed our minds. Now, we’ve turned our attention to another crucial element in a loudspeaker cone: the fabric spider. Our 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 our Midnight Blue Metallic models and full-grain black leather for our California Burl Gloss models.

Crossover
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. We use luxurious, full-grain blue leather for Midnight Blue Metallic, and full-grain black leather for California Burl Gloss.
