The phase on the sub I thought had to do with it's direction of travel. Correctly wired, it will push the air, wired backwards it draws itself into the cabinet. This creates a noticeable drop in sound level.
This is similar to reversing the red/black wires on a speaker. In a 2 channel setup, you would notice that one of the speakers is not as "loud" as the other. This is because the cones are moving out of sync.
There is also discussion that the cable run for the sub affects it's phase, and that you should test the phase setting while in the main seating position to determine the position that has the "most" bass. Do not be surprised if you do not notice a difference.
Also, keep in mind that the frequencies the sub carries require a minimum of 4' to develop properly and carry further (which is why your neighbor knows when your watching a movie).
If you use RCA cables to connect the sub, you will not likely reverse the phase, leave it at 0.
This is how it was all explained to me. I am open to being told differently.
