Q. What does the Phase Invert switch on my subwoofer do?
Answer:
Use of the "Phase Invert" switch is to help with integrating the sub
with the rest of the speakers using polarity, and the best setting depends on the
placement of the other speakers relative to the subwoofer and room
acoustics.
Our suggestion is to play some music you
are familiar with and experiment with the Phase Invert setting and level
control until you hear a good blend between the front speakers and the
subwoofer. If you can hear the subwoofer standing out it’s too loud!
