The 804 D3 delivers incredible acoustic transparency, thanks to unique 800 Series Diamond features such as our Continuum cone and augmented
Matrix bracing system. So while its looks may be conventional, its performance is anything but.
804D3 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.
