Description The 805 D4 Signature stand-mount loudspeaker is compact and powerful. It features fully optimized technologies, including that all-important Diamond Dome tweeter and Solid Body Tweeter-on-Top. It’s proof positive that small can still be beautiful. The Bowers & Wilkins 805 D4 Signature standmount speaker 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. 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.
