804 D3 (GLOSS BLACK) : B&W
The 804 D3 delivers incredibly high-performance sound in a traditional loudspeaker form with a smaller footprint.
The 804 D3 is a traditional-looking floorstanding speaker featuring cutting edge technology. The ultra-rigid cabinet plays host to a Diamond Dome tweeter, Continuum cone midrange and Aerofoil bass drivers. All of these come together to generate room filling, highly detailed performance.
Bracing is essential in keeping a speaker stable, so the character of instruments comes through cleanly. Developed using computer modelling and constructed from wood ply with metal reinforcement, Matrix offers the ultimate in bracing.
The Continuum cone delivers pristine midrange performance by effectively negating the break-up behaviour that can adversely effect this all-important part of the spectrum.
The Aerofoil cone’s variable thickness provides added strength where it is needed to maintain its pistonic shape, delivering rock sold bass.
