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.
Hear small details in a big way
Mounted atop the main enclosure, the Diamond dome tweeter in its solid aluminium housing delivers space, ambience and precise soundstage imaging.
Less resonance, more dispersion
The Turbine Head’s massive mid-range housing is carefully shaped and inert, ensuring voices and instruments are delivered with extreme purity.
Truly amazing sound
Voices and instruments are delivered with purity and precision, thanks to the smooth, accurate Continuum™ cone mid-range driver.
Nimble and powerful
Solid, dramatic bass is delivered through the rigidity and lightness of the uniquely-shaped variable thickness Aerofoil™ cone.
