KEF Q800DSWH Dipole Loudspeakers - White (Pair) Thanks to the latest computer modelling techniques, years of painstaking development, and a dash of design genius, the new iteration of the Uni-Q driver array packs a formidable complement of design innovations. Based on the state-of-the-art HF driver developed for Concept Blade, the Q boasts a much larger (1 in. dome) tweeter for increased sensitivity and distortion-free power handling. It plays as loud as it plays true. Featuring rigid new aluminium cone technology just like the Uni-Q array, the Q Series advanced bass driver is a tour de force in its own right. A die-cast aluminium chassis rigidly locates the high efficiency vented magnet assembly to prevent unwanted resonance, and the large voice coil ensures impressive power handling. Its musicality is impeccable: seductively tuneful and well controlled, and on the floorstanding models, complemented by dedicated front-firing auxiliary bass radiators (ABRs).
