DetailsAs wonderfully versatile as its smaller brother the 805 Diamond, the elegant, floorstanding 804 Diamond has an even more commanding acoustic presence, thanks to a true three-way design incorporating two Rohacell® bass units, an FST™ midrange and a diamond dome tweeter delivering pin-sharp clarity all the way up the frequency range. A brilliant all-round performer for any occasion.
The hypothetical perfect tweeter is one that balances infinite stiffness with near-zero density. Only one material on earth comes close to matching those properties: diamond. Thanks to modern scientific techniques, we can grow diamond, like a crystal, to form the optimum tweeter dome shape. The result is truly exceptional sound at high frequencies. And it comes as standard with every speaker in the range, including the 804 Diamond.
For a long time, we thought our Kevlar® midrange cones couldn’t get any better – but then we came up with the fixed suspension transducer (FST for short). FST enhances the properties of Kevlar by acting like a circular shock absorber around the cone, absorbing the sound-smudging bending waves that travel outwards to the perimeter. A midrange driver never sounded cleaner, or more responsive.
