Bowers & Wilkins 803 D4
The smallest 800 Series Diamond model to feature the revolutionary Turbine Head, 803 D3 is designed for clarity, power and purity even in modestly-sized listening rooms.
Mounted atop the main enclosure, the Diamond dome tweeter in its solid aluminum housing delivers space, ambience and precise soundstage imaging.
The Turbine Head’s massive midrange housing is carefully shaped and inert, ensuring voices and instruments are delivered with extreme purity.
Voices and instruments are delivered with purity and precision, thanks to the smooth, accurate Continuum™ cone midrange 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.
Perfect sound is about moving air, not the speakers: a stable plinth makes for easy positioning, then keeps it rock-solid for listening.
