Bowers & Wilkins 803 D4 Floorstanding Speaker

Description

803 D4

The Bowers & Wilkins 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. The 130 mm (5-in) midrange cone is carefully isolated from the impact of its bass cones thanks to its Turbine Head enclosure.

Instead of a conventional loudspeaker box, the 803 D4 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.

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 the best yet, ensuring optimum scale, power and intelligibility

803 D4 mounts two Aerofoil™ bass cones in twin solid aluminium bass pods, each of which is clamped into an aluminium 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.

The 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.

Bowers & Wilkins

Bowers & Wilkins (B&W) is now a very large company, with distribution chains and customers all over the world. However it began in 1966 with John Bowers hand-assembling speaker systems for local clients in Worthing, West Sussex, in the back of the electrical store that he ran with his friend Roy Wilkins.

Five decades later the company is a global leader in sound, and in 2016 Bowers & Wilkins were incredibly proud to celebrate their 50th anniversary – and even more proud that the ethos, passion and drive of its founder is still a vital element in its continuing success.
