Our highest performance stand mount ever
The 805 D4 Signature brings new standards of performance and capability in a smaller, more room-friendly form factor than its mighty sibling. As with the larger 801 D4 Signature model, the 805 D4 Signature also includes an all-new grille mesh for more openness and transparency plus an upgraded crossover with new bypass capacitors. In addition, an all-new bass / midrange motor system features upgraded performance from its 165mm (6.5”) drive unit, ensuring both a cleaner delivery through the midrange plus more extended bass. Finally, it features mechanical revisions to its aluminium top plate aimed at further reducing unwanted noise and vibration from the structure.

Exclusivity celebrated
To properly identify their prestigious position within the Bowers & Wilkins portfolio, both the 801 D4 Signature and 805 D4 Signature are only available in two exclusive new finishes. The Midnight Blue Metallic paint is the same as offered on the iconic Nautilus loudspeaker, featuring a total of eleven coats of paint and lacquer that are machine polished to a gleaming and lustrous finish. Excluding curing times, the paint application process alone is in excess of 18 hours of labour. Midnight Blue Metallic loudspeakers are further
celebrated with a bespoke blue Leather by Connolly trim on the top plate.
Alternatively, both models can be purchased in an exceptional California Burl Gloss wood veneer, featuring unique wood figuring and a luxurious high gloss finish trimmed in black Leather by Connolly. The wood veneer is sustainably sourced engineered wood from Italian specialist, ALPI. Including no less than fourteen coats of lacquer and multiple sanding processes, the total finishing time for a single 801 D4 Signature in California Burl Gloss is in excess of 24 hours

All-new tweeter grille
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 805 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.

Continuum™ Cone
Thanks to its composite construction, the Continuum™ Cone avoids the abrupt transitions in behaviour that can impair the performance of a conventional drive unit. The result is a more open, neutral performance from the 805 D4 Signature. Voices and instruments can be heard with precision and transparency.
