Straight Up Great Sound
The 804 D3 Diamond Series Floorstanding Loudspeaker is a traditional-looking model featuring cutting edge technology. The ultra-rigid cabinet plays host to a Diamond Dome tweeter, Continuum cone midrange, and Aerofoil bass drivers. All of these come together to generate room filling, highly detailed performance.
Bracing is essential in keeping a speaker stable, so the character of instruments comes through cleanly. Developed using computer modeling and constructed from wood ply with metal reinforcement, the Matrix offers the ultimate in bracing.
The Continuum cone delivers pristine midrange performance by effectively negating the break-up behavior that can adversely affect this all-important part of the spectrum.
The Aerofoil cone’s variable thickness provides added strength where it is needed to maintain its pistonic shape, delivering rock-sold bass.
