802 Diamond
If you’re looking for a speaker with the power, clarity and presence of the mighty 800 Diamond, but your listening area can’t quite accommodate its studio-sized proportions, the 802 Diamond is the answer. Retaining the groundbreaking spherical head design of its bigger brother, it’s the closest you’ll get to true studio sound at home.
Rewriting the rules
In the 1990s, we embarked on our most ambitious project yet – to fulfill John Bower's dream and build the ultimate loudspeaker. Five years of research and development later, and the result was revealed. Rewriting all the rules for how a speaker should be designed, Nautilus™ produced a sound so real you could almost reach out and touch it. The technological innovations we developed for Nautilus live on today, in the 800 Series Diamond.
BEHIDE THE SCENES
The 800 Series Diamond is more than a speaker. It represents the pinnacle of our technological achievement, and the sum total of almost 50 years of research and development at the cutting edge of acoustic design. Inside the sturdy cabinet of every speaker in the range is some of the most advanced technology ever to be put inside a box.
Tweeter
Hard enough to cut stone and grind glass, diamond is a miracle material, used in advanced industrial applications like the Large Hadron Collider at CERN. Its combination of lightness and incredible stiffness also makes it the perfect tweeter material, capable of producing high frequencies way beyond the range of human hearing. Using modern scientific processes, we grow diamond under laboratory conditions to form the optimum tweeter dome shape.
