The Phase Control determines whether the subwoofer speaker’s piston-like action moves in and out with the main speakers, 0°, or opposite the main speakers, 180°. There is no correct or incorrect set- ting. Proper phase adjustment depends on several variables such as subwoofer placement and listener position. Adjust the phase switch to maximize bass output at the listening position.
