Floorstanding speaker
The flagship of the 800 Series Diamond range is a no-compromise design: behind that strong visual statement is half a century of design and engineering, all in the cause of greater musical insight and impact.

Hear small details in a big way
Mounted atop the main enclosure, the Diamond dome tweeter in its solid aluminum housing delivers space, ambience and precise soundstage imaging.

Less resonance, more dispersion
The Turbine Head's massive midrange 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 midrange driver.

Nimble and powerful
Solid, dramatic bass is delivered through the rigidity and lightness of the uniquely-shaped, variable thickness Aerofoil™ cone.

Braced for impact
Unwanted resonances can blunt the punch of the sound: advanced Matrix bracing keeps the cabinet ultra-rigid and damps out superfluous vibrations.

Stable foundations
Perfect sound is about moving air, not the speakers: a stable plinth makes for easy positioning, then keeps it rock-solid for listening.
