B&K Reference 30 - System Setup: Subwoofer Phase; Subwoofer Phase Adjustment

Set subwoofer phase - In addition to the subwoofer location adjustment (see Speaker Location above), your
processor has an option to ‘invert the phase’ of the information sent to the subwoofer. This adjustment is
sometimes needed to correct ‘lack of low end’ problems created with the interaction between the subwoofer and
other large speakers in a listening room. The correct subwoofer phase adjustment is the one which allows the
loudest listening level.
