804 Diamond

The elegant floorstanding 804 Diamond offers a commanding acoustic presence 
and incorporates diamond tweeter technology for the first time. A true three- way 
design, it also features two Rohacell bass units and a woven Kevlar FST midrange 
driver. This combination ensures that it delivers pin-sharp clarity all the way up the 
frequency range.
