Description
It might have a more traditional appearance than other speakers in the range, but don’t let that fool you. 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.
