Overview

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.

Features

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.
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.

Why step up from 805 D4 to 804 D4? First, 804 D4 is a three-way speaker, with twin 165mm (6.5-in) Aerofoil™ bass cones – and that has huge benefits to its power and scale. Second, as a three-way speaker, it includes a dedicated midrange cone, so voices and other details will sound more accurate. Discover 804 D4
