As noted in our earlier post, Uni-Core uses dual opposed “force-cancelling” drivers that are concentrically arranged and share a single motor. According to KEF, this design “allows the cabinet size to be reduced by over a third while equaling or exceeding the driver excursion of a much larger subwoofer.” The KC62 also uses an “Origami” surround that resists pressure within the sealed cabinet without restricting sensitivity. Tech innovation number three is a Smart Distortion Control motional feedback system that reduces “signal abnormalities” by “measuring the current in the voice coil, detecting, and then correcting any non-linear distortions,” according to KEF.
