KEF'S UNI-Q

摘要

With its Uni-Q combination driver, first seen in 1988, KEF has aimed to overcome a fundamental disadvantage of conventional multi-way speaker systems, by ensuring that sound over the whole frequency range can emanate from the same point in space. KEF was not the first company to combine a tweeter with a bass unit, as Tannoy's Dual Concentric concept dates back to 1947. But KEF was able to take advantage of the new magnet material, neodymium-iron, to create a miniaturised tweeter that would fit into the centre of the bass/mid unit at the front, so that the two centres of radiation were truly coincident. Later generations of Uni-Q drive units have refined overall performance almost out of all recognition, by perfecting the integration of the two elements. These efforts have culminated in the current combination of two-part metal tweeter dome and metal midrange cone.
