The 804 D3 delivers incredibly high-performance sound in a traditional loudspeaker form with a smaller footprint.
Straight up great sound
The 804 D3 is a traditional-looking floorstanding speaker 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.
The Continuum cone delivers pristine midrange performance by effectively negating the break-up behaviour that can adversely effect 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.
Diamond Dome Tweeters
Incredibly light, yet unbelievably rigid, Diamond is the ultimate tweeter material. Delivering the most revealing, natural treble you will ever hear.
Bracing is essential in keeping a speaker stable, so the character of instruments comes through cleanly. Developed using computer modelling and constructed from wood ply with metal reinforcement, Matrix offers the ultimate in bracing.
