Sometimes I wish the phase control on subwoofers never existed at all, because I can't seem to leave the switch on mine alone for more than a couple of hours.

I ran the sub polarity test on Avia today, and a phase of 180 gave me the higher SPL. I found this odd, as most people use the 0 setting when their sub is in front of the room like mine, but I rolled with it.

I then tested a clean, single-noted bass track, and the sub's output seemed non-existant. Switching the sub back to the 0 setting brought the bass back, and the music sounded naturally fuller.

Then I put in Incredible Hulk BD, and started playing the intro. But at 0 phase, I couldn't really feel the bass behind the strings in the music, so I tried switching it back to 180...and everything sounded fuller.

How the hell do you find the "right" phase setting? Because I figure that it must be completely variable, and depends on the frequency.

Adjusting the phase based simply upon which setting "sounds" loudest can be very misleading. A particular setting may simply be accentuating a room peak.

The correct phase setting is the one that provides you with the flattest FR. With only the ability to flip the polarity 180°, you are limited. Adjusting the subwoofer's distance setting will provide you with much finer attenuation.
