The loudspeaker that sets the standard other high-end designs will be judged by for years to come. Endowed with every new technology the 800 Series Diamondhas to offer, the reference-quality 801D4 is an instant icon.
40 years of excellence
Innovation. 801 D4 is defined by it. In each of its incarnations over the decades, 801 has always been the most advanced loudspeaker that we know to make at that particular point in time, a showcase of all our newest technologies and most original thinking. Small wonder it has become an icon.
The ultimate Matrix
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 801D4 is our best yet, upgraded with extensive aluminium bracing to reinforce key stress points.
TurbineHead
The all-aluminium Turbine Head houses our Continuummidrange cone in a stiff and critically damped enclosure to eliminate unwanted resonances. At the same time, its decoupled from both the bass enclosure and the tweeter body. The result? The most realistic midrange sound yet.
Biomimetic Suspension
Sometimes, making a big difference takes unconventional thinking. Our new Biomimetic Suspension revolutionises midrange performance by greatly reducing the unwanted air pressure and coloration that a traditional fabric spider can generate. The result? Midrange transparency you wouldnt believe.
The state of our art
801 D4 is our flagship and the most powerful model in the new 800 Series Diamond range. Its no-compromise design includes all our most advanced technologies in their purest, most optimised form alongside crossover components of the highest quality. You want our reference loudspeaker? This is it
