Description Bowers & Wilkins 805 D4 Bookshelf Speaker The Bowers & Wilkins 805 D4 Bookshelf Speaker might be smaller than its tower speaker siblings, but it’s no lightweight: its beautifully constructed Reverse-Wrap cabinet, stiff aluminum bass pods and 165mm (6.5-in) Continuum™ mid-bass cone afford it exceptional bass extension and scale for a relatively compact speaker. View User Manual >> View Specifications >> View 800 Series >> Review “The 805 D4 is a masterclass in creating a truly magnificent soundstage that is always proportionate to the music being played and into which the speakers themselves simply vanish.” AV Forums – 805 D4 Best Buy Award Features Solid yet sparkling performance Highly accurate soundstaging Reverse wrap design looks great Diamond dome tweeter One of their 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. 15 years after they introduced it, they haven’t found a better tweeter dome technology. Solid Body Tweeter assembly Bowers & Wilkins newest Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system, producing an even more free and open sound with high frequencies. The carefully decoupled housing is milled from a single solid block of aluminum to better resist resonance. Rear-mounted crossover The new reverse-wrap orientation of the cabinet on 805 D4 means they can place its sensitive crossover components inside their own, dedicated space within the cabinet, which has critical benefits to both performance and serviceability. They’ve taken the opportunity to upgrade the speaker terminals, too. The science of sound Innovation is at the heart of everything Bowers & Wilkins do. They question, examine, understand and then evolve. They use computer modelling to explore and reimagine every aspect of loudspeaker design. Go large Why step up from 805 D4 to 804 D4? First, 804 D4 is a three-way speaker, with twin 165mm (6.5-in) Aerofoil™ bass cones – and that has huge benefits to its power and scale. Second, as a three-way speaker, it includes a dedicated midrange cone, so voices and other details will sound more accurate.
