| The 703 is a full 3-way design. Twin bass drivers, their stiff paper/Kevlar® cones further strengthened by our unique girder-like mushroom construction, work in parallel in a Flowport-tuned cavity to handle all the bass frequencies.
Freed from the need to produce any bass signals, the FST dedicated midrange driver operates in its own isolated cavity within the cabinet. The combination of its woven Kevlar® cone and mechanically matched outer suspension enables this driver to portray the finest nuances in the signal, giving instruments their correct timbral character and positioning them accurately on the sound stage.
The tube-loaded tweeter is freely mounted on top of the cabinet to give a sense of airiness and reduce the listeners' awareness of the speakers as discrete sound sources.
