B&W's 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.
803 D4 features all the most iconic ingredients in the 800 Series Diamond range including, of course, that famous headed enclosure. It is, however, smaller than its other siblings. Step up to the 802 D4, and you’ll get both larger 200mm (8-in) bass cones and a larger 150mm (6-in) midrange driver.
Small wonder
Enhanced Matrix™
Matrix bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage. The Matrix assembly in 803 D4 is our best yet, ensuring optimum scale, power and intelligibility.
Aluminum bass pods
803 D4 mounts two Aerofoil™ bass cones in twin solid aluminum bass pods, each of which is clamped into an aluminum plate fixed to the stiffest part of its curved cabinet. Formed as single pieces of metal, these stiff structures provide the perfect mechanical location for those powerful bass cones.
