Little Diamond
805 D4 might be smaller than its floor-standing siblings, but it’s no lightweight: its beautifully constructed Reverse-Wrap cabinet, stiff aluminium 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 aluminium 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.

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.

The 805 D4 is a masterclass in creating a truly magnificent soundstage that is always proportionate to the music being played and into which the speakers themselves simply vanish.
