Should there ever be a reason to throw the left and right channels of a system out of phase? We have a LA Audio EQ231G-SP and the phase switch can do some interesting things. I am under the impression that you don't want your mains to be out of phase...but the bass response changes drastically when I throw the left side out of phase (it sounds HUGE when out of phase, and balanced when in phase). I think that our subs could be aligned much better...the bass response with both channels in phase is lacking in the center of the room. Has anybody messed around with this before?
