Correcting the subwoofers phase
If trying to boost the bass output of the sub-
woofer doesnt do much or rather makes you
feel that the bass gets more murky, this may
indicate that the subwoofers 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.
