    Bowers & Wilkins 803 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.

    Bowers & Wilkins's most compact-headed model brings all the technical advantages of a dedicated midrange enclosure to a smaller footprint that’s easily accommodated in any home. Small doesn’t mean compromised, either: 803 D4 still bristles with technical innovation throughout.

    B&W's all-new Biometric Suspension revolutionises midrange cone performance by greatly reducing the unwanted air pressure and coloration that a conventional fabric spider can generate. The result? Midrange transparency you wouldn't believe possible.

    803 D4 mounts two Aerofoil bass cones in aluminum base pods, each of which is clamped into an internal aluminum plate fixed to the stiffest part of its cabinet. Formed as single pieces of metal, these structures provide the perfect location for clean, accurate bass.

    The B&W 803D4 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
