TEST BENCH

All of the KEF iQ Series speakers have a fairly smooth response, although the iQ50 tower and iQ60C center speaker exhibit a mild, broad dip in the midrange between about 1.5 and 4.5 kHz. Off-axis response of all models is excellent; except for a slight treble rolloff, there are no significant anomalies, even at a 60° angle. The subwoofer doesn't deliver particularly high output, but its response is impressively even: Average output is 96 dB at 10% distortion or lower, and maximum output is 102 dB at 63 Hz.
