KEF Q200CB Center Channel Loudspeaker - Black Ash (Single) The Q200C uses a 5.25 Uni-Q driver array, flanked by two 5.25 bass drivers, to properly fill your home theater with an undistorted and incredibly full sound. Our Uni-Q driver array perfectly replicate dialogue in any movie with incredible precision. The two drivers that comprise the Uni-Q act as one source, much like the human voice, to give you the best listening experience possible. The Uni-Q array is complimented by the duet of 5.25 inch bass driver, which serve to bring you all the thudding, booming low-end frequencies without a hint of distortion. Our Z-flex surround on the Uni-Q drivers smooth the transition to the front panel, allowing the Q200c to deliver clean, punchy sound without colorization.
