Phase Control
The Phase Control determines
whether the subwoofer’s
piston-like action moves in
and out in phase with the
main speakers or opposite
the main speakers. There is
no correct or incorrect
setting. Proper phase
adjustment depends on
several variables such as
subwoofer placement and
listener position. Adjust the
phase switch to maximize
