The Aerofoil bass cone technology remains an outstanding solution to the conundrum of combining low mass and high stiffness in bass cones, thanks to its carbon-fibre skin and variable-profile foam core. Now, foam Anti-Resonance Plugs have been added for lower distortion and even cleaner bass.

Matrix bracing uses interlocking panels to reinforce loudspeaker cabinet walls in all directions internally, reducing resonance and creating a more believable soundstage. The Matrix assembly in 802 D4 is the best yet, upgraded with extensive aluminium bracing to reinforce key stress points.

The all-aluminium Turbine Head houses the Continuum midrange cone in a stiff and critically damped enclosure to eliminate unwanted resonances. At the same time, it's decoupled from both the bass enclosure and the tweeter body. The result? The most realistic midrange sound yet.

Sometimes, making a big difference takes unconventional thinking. The new Biomimetic Suspension revolutionises midrange performance by greatly reducing the unwanted air pressure and colouration that a traditional fabric spider can generate, resulting in midrange transparency you wouldn't believe.

The 802 Diamond D4 is the flagship and the most powerful model in the new 800 Series Diamond range. Its no-compromise design includes all the most advanced technologies in their purest, most optimised form alongside crossover components of the highest quality for reference-level sound.
