    Nearly every powered subwoofer has built-in lowpass filters and some have built-in signal processing.  These components add electrical delay to the signal in addition to the acoustical delay due to the distance of the sub from the listening position.  MultEQ measures the total signal delay and compensates so that the signal from the subwoofer arrives at the same time as the signals from the other speakers.
