Excellence. Evolved. This is not just another speaker range. Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins. This is their benchmark, their icon; the most advanced range of loudspeakers they know how to make. For Bowers & Wilkins, the 800 Series Diamond is everything they know, and everything they are. The 805 D4 stand-mount loudspeaker is the most compact model in the 800 Series Diamond range, but it's still packed with advanced technologies, including that all-important Diamond dome tweeter and Solid-Body Tweeter-on-Top. It's proof positive that small can still be beautiful. Features Diamond tweeter Solid-body Tweeter-on-Top Continuum cone bass/mid-Matrix Anti-Resonance plug Flowport Solid-Body Tweeter The iconic Solid-Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system, creating an even more free and open sound with high frequencies. As before, the carefully decouples housing is milled from a single solid block of aluminum to better resist resonance. Rear-Mounted Crossover All stereo models in the new range now use rear-mounted crossover designs mounted on stiff aluminum spines. This isolates the sensitive capacitors from the effects of air pressure within the enclosure.
