Phase option on sub
Discussion
It changes the phase of the drive unit.
i.e. at 0 deg phase, the bass speaker will be "pushing" in time with the rest of the speakers in your system, with the switch set at 180 deg, the base speaker in your sub will be "pulling" while everything else is "pushing" - it is therefore out of phase with the input signal. (This assumes you have wired up the rest of your system correctly, so all reds to reds, and speaker cables linked to correct amplifier terminals.)
When some speakers are pushing while others are pulling, you can get bass cancelation, which means that one speaker is counteracting another. This will be apparent as a lower volume in the base region.
The switch is provided as subs are often placed some distance away from your main speakers, and therefore may be out of phase with the rest of the system. The way to set it up, is for you to sit in your usual listening position, and get someone to switch the phase switch while playing bass heavy music (or better still some test frequencies), and listen for any dips in the base response. Leave the switch in the position which pleases your ears the most.

Good explanation Teetertank ~ IMHO best to leave phase switched to where the bass is loudest at the listening position ie main speakers and sub output adding together. If they are cancelling each other then amp power and headroom is being wasted. i.e. at 0 deg phase, the bass speaker will be "pushing" in time with the rest of the speakers in your system, with the switch set at 180 deg, the base speaker in your sub will be "pulling" while everything else is "pushing" - it is therefore out of phase with the input signal.
