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
bass output at the listening
position.
Remember, every system,
room and listener is different.
There are no right or wrong
settings; this switch
¡ offers
the added flexibility to adjust
your subwoofer for optimum
performance for your specific
listening conditions without
having to move your speakers.
If at some time in the future
you happen to rearrange your
listening room and move
your speakers, you should
experiment with the Phase
switch
¡ in both positions,
and leave it in the position
that maximizes bass
performance.
