The KEF subwoofer is a stunning new iteration of KEF's landmark innovation: the Uni-Q point source MF/HF driver array. the shape and bracing geometry of the cabinets are computer-optimized to minimize secondary radiation from the cabinet walls and distortion from standing waves. With constrained layer damping to absorb residual vibrations, they're engineered to eliminate any panel resonance, stray reflections or box coloration effects that would compromise the purity of the sound.All Rights Reserved
