805 D4

The 805 D4 stand-mount loudspeaker is the most compact model in the 800 Series Diamond range, but its 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 its 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 havent 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. Weve taken the opportunity to upgrade the speaker terminals, too.

The science of sound

Innovation is at the heart of everything we do. We question, we examine, we understand and then we evolve. We use computer modelling to explore and reimagine every aspect of loudspeaker design. Learn more about all the technologies that combine to make 800 Series Diamond so special here.
