    Bowers & Wilkins 805 D4

    This is not just another speaker range. Each new generation of 800 Series Diamond is a landmark event for Bowers & Wilkins. This is a B&W benchmark, an icon; the most advanced range of loudspeakers, B&W knows how to make. The 800 Series Diamond is everything Bowers & Wilkins know, and everything we are.

     Technical features

    • Diamond tweeter
    • Solid-body Tweeter-on-Top
    • Continuum cone bass/mid
    • Anti-Resonance plug
    • Matrix™
    • Flowport

    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.

    Our 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 decoupled housing is milled from a single solid block of aluminum to better resist resonance.

    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.

    The B&W 805D4 will be on demonstration at Martins HI-Fi and we will also be hosting a future event. If you wish to book a private demonstration please contact us via the chatbox, call 01603 627010 or email info@martinshifi.co.uk
