Bowers & Wilkins 804 D4
With all the qualities and advanced drivers of the 800 Series Diamond in a slimline cabinet, 804 D3 floorstanding speaker delivers a detailed, room-filling sound.
Mounted atop the main enclosure, the Diamond dome tweeter in its solid aluminum housing delivers space, ambience and precise soundstage imaging.
Voices and instruments are delivered with purity and precision, thanks to the smooth, accurate Continuum™ cone mid/bass driver.
Solid, dramatic bass is delivered through the rigidity and lightness of the uniquely-shaped, variable thickness Aerofoil™ cone.
Unwanted resonances can blunt the punch of the sound: advanced Matrix bracing keeps the cabinet ultra-rigid and damps out superfluous vibrations.
