Correcting the subwoofer
s phase
If trying to boost the bass output of the sub-
woofer doesn
t do much or rather makes you
feel that the bass gets more murky, this may
indicate that the subwoofer
s output and bass
content you hear over other speakers cancel
each other out. To remove this problem, try
changing the phase setting for the subwoofer.
