The 805 D4 stand-mount loudspeaker is the most compact model in the 800 Series Diamond range, but it's still packed with advanced technologies, including the Diamond dome tweeter and the Solid Body Tweeter-on-Top. * Stand(s) not included.

Little Diamond

805 D4 might be smaller than its tower speaker siblings, but it’s no lightweight: its beautifully constructed Reverse-Wrap cabinet, stiff aluminum bass pods and 165mm (6.5-in) Continuum™ mid-bass cone afford it exceptional bass extension and scale for a relatively compact speaker.
Diamond dome tweeter
One of our most significant accomplishments over the past two decades, the ultra-stiff, supremely accurate Diamond dome tweeter is the perfect combination of low mass, exceptional stiffness and outstanding accuracy. 15 years after we introduced it, we haven’t found a better tweeter dome technology.

Solid Body Tweeter assembly

Our newest Solid Body Tweeter-on-Top housing features an elongated form with a longer tube-loading system, producing an even more free and open sound with high frequencies. The carefully decoupled housing is milled from a single solid block of aluminum to better resist resonance.

Rear-mounted crossover

The new reverse-wrap orientation of the cabinet on 805 D4 means we can place its sensitive crossover components inside their own, dedicated space within the cabinet, which has critical benefits to both performance and serviceability. We’ve taken the opportunity to upgrade the speaker terminals, too.
