Bowers & Wilkins 805 D4 Signature Loudspeaker

Description The Bowers & Wilkins 805 D4 Signature is a stand-mount loudspeaker that combines compact design with exceptional acoustic performance. Despite its smaller size, it incorporates fully optimized technologies drawn directly from the company’s flagship models, proving that true high-end sound does not require a large cabinet. At its core is the acclaimed Diamond Dome tweeter, delivering unmatched clarity, precision, and extension in the high frequencies. This is complemented by the brand’s signature Solid Body Tweeter-on-Top design, which features a refined elongated housing and carefully engineered grille for a more open and natural presentation of sound. Crafted with meticulous attention to detail, the 805 D4 Signature is a perfect balance of engineering and elegance offering powerful, room-filling sound in a refined, compact form that exemplifies the philosophy that small can still be beautiful. 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. 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. Aluminium Top-Plate Every new 800 Series Signature model has a significantly upgraded cabinet design with an all-new, optimised aluminum top section for even greater stiffness. The same design also provides a perfect mounting point for 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.
