Bowers & Wilkins - 803 D4

Bowers & Wilkins - 803 D4  (SOLD AS A PAIR) Floorstanding Speaker Our most compact headed model brings all the technical advantages of a dedicated midrange enclosure - the Turbine™ Head, with its decoupled midrange cone - to a smaller footprint that's easily accommodated in any home. Small wonder 803 D4 may be notably more compact than the 801 D4 or 802 D4, but it still bristles with technical innovation, most obviously in its use of a three-box construction. Its 130mm (5-in) midrange cone is carefully isolated from the impact of its bass cones thanks to its Turbine Head enclosure. Reverse Wrap cabinet Instead of a conventional loudspeaker box, our cabinets are made from a continuous curved section of wood, with the drive units mounted at the heart of the curvature. This stiffer, more inert structure resists mechanical resonances far better and also ensures better dispersion of sound.
