(1993-98) This was the flagship and reference model and the first dedicated center channel from the top tier manufacturers. It is a two-way speaker that uses KEF's special Uni-Q construction with the tweeter mounted in the center of the woofer. The Uni-Q approach creates excellent dispersion in the listening area which helps ensure clear dialog to listeners in various positions in the room. It also has pinpoint imaging, a must in surround systems.
