805 D4 Signature

Compact and powerful, the 805 D4 Signature stand-mount loudspeaker features fully optimised technologies, including the Diamond Dome tweeter and Solid Body Tweeter-on-Top. It’s proof positive that small can still be beautiful.

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 still have not found a better tweeter dome technology.

The 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.

The 805 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.

Featuring the beautifully-constructed Reverse-Wrap cabinet, stiff aluminium bass pods and 165 mm Continuum™ mid-bass cone, these premium offerings afford it exceptional bass extension and scale for a relatively compact speaker.

Bowers & Wilkins

Bowers & Wilkins (B&W) is now a very large company, with distribution chains and customers all over the world. However it began in 1966 with John Bowers hand-assembling speaker systems for local clients in Worthing, West Sussex, in the back of the electrical store that he ran with his friend Roy Wilkins.

Five decades later the company is a global leader in sound, and in 2016 Bowers & Wilkins were incredibly proud to celebrate their 50th anniversary – and even more proud that the ethos, passion and drive of its founder is still a vital element in its continuing success.
