800 D3

A revolutionary reinvention of the reference speaker

 

Reviewed by the experts

"Highly revealing of the purity of tone of instruments, these floorstanding speakers are just as capable of snarl or stomach-rearranging punch."
-Hi-Fi News

 

 

“This is the first time we’ve realized this level of power and refinement at the same time.”
-CEPro

 
 

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.
