Bowers & Wilkins 803 D4 (Paire) - Shiny black - White - Walnut - Rosenut

Description

The most compact headed model brings all of the technical advantages of a dedicated midrange enclosure - the iconic Turbine Head - 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.

Turbine Head

Hear the sound, not the cabinet. Bowers & Wilkins is used separate midrange enclosures on 800 Series models from the very beginning: now, the all-aluminum

housing takes the concept to the next level. This phenomenally stiff and inert housing for the crucial midrange cone is carefully damped to avoid unwanted resonances and decoupled from both the bass enclosure and the tweeter body. The result? The most realistic midrange sound yet.

Solid Body Tweeter

The latest incarnation of the iconic Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system, producing 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.

Matrix

Matrix bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage. Every loudspeaker in the 800 Series Diamond benefits from an upgraded Matrix design that combines solid plywood construction with aluminum bracing to reinforce key stress points.

Reverse wrap cabinet

When it came to designing the ideal shape for the 800 Series Diamond cabinet, Bowers & Wilkins did a U-turn. Quite literally. Instead of a flat-fronted speaker with a curving back, Bowers & Wilkins produced a cabinet with a front and sides formed of one continuous curve, held together with a spine of solid aluminum. Fewer joins make for a stiffer, more inert structure, and a curved front means less baffling around the drive units. So sound dispersion is improved, and cabinet reflection is reduced.

Biomimetic Suspension

Sometimes, making a big difference takes unconventional thinking. For decades, Bowers & Wilkins thought nothing could improve on the sound of the famous yellow Aramid Fiber midrange cones, but eventually Continuum cone technology changed minds. Now, Bowers & Wilkins has turned an attention to another crucial element in a loudspeaker cone: the fabric spider. The Biomimetic Suspension revolutionizes 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.

Decoupled midrange

Every 800 Series Diamond loudspeaker has a dedicated midrange cone using several proprietary Bowers & Wilkins technologies: the Continuum FST cone, Biomimetic Suspension and midrange decoupling, the latter ensuring minimal interference from the operation of the loudspeaker's bass units.

Aluminum top plate

Every stereo model in the 800 Series Diamond range has a significantly upgraded cabinet design with an aluminum top plate for even greater stiffness and as a result, even more realism. The same design also provides a perfect mounting point for Leather by Connolly cabinet detailing.

Rear-mounted crossover

All stereo models in the 800 Series Diamond range now use rear-mounted crossover designs mounted on stiff aluminum spines. This isolates the sensitive capacitors from the unwanted effects of air pressure within the enclosure and makes for a very effective heatsink to ensure optimum performance when in use.
