- About Signature
The name ‘Signature’ is one of the most illustrious and evocative in the Bowers & Wilkins canon. We apply it sparingly, carefully – and only when the product concept we’ve got in mind is appropriate and consistent with the narrative that underpins our Signature models. Every Signature model has had its own unique identity and at the same time, every model has been connected to its predecessor by several common threads: no-holds-barred performance, unique, distinctive beauty and special-edition exclusivity. Signature is a level above the best. This is us perfected. - 805 D4 Signature
The 805 D4 Signature standmount loudspeaker is compact and powerful. It features fully optimised technologies, including that all-important Diamond Dome tweeter and Solid Body Twetter-on-Top. It's proof positive that small can still be beautiful. - Solid Body Tweeter
The latest incarnation of our 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 optimised 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 aluminium to better resist resonance. - Reverse Wrap Cabinet
Instead of a flat-fronted speaker with a curving back, our 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. - Continuum Cone™
Thanks to its composite construction, the Continuum™ Cone avoids the abrupt transitions in behavior that can impair the performance of a conventional drive unit. The result is a more open, neutral performance that delivers voices and instruments with precision and transparency. - Compact and Powerful
The 805 D4 Signature stand-mount loudspeaker is compact and powerful. It features fully optimized technologies, including our Diamond Dome tweeter and Solid Body Tweeter-on-Top. It's proof positive that small can still be beautiful. - Diamond Dome Tweeter
One of our 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 we introduced it, we haven't found a better tweeter dome technology. - 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.
