Axiom Home Page Forums General Discussion Technical Questions EP175 Audio/video switch and phase switch

If the subwoofer is about the same distance from your seats as the main speakers leave the switch on 0 and don't worry about it (or try the following tests anyways).

If the sub is way off to one side play something with deep bass (preferably a mix of frequencies) and have SOMEONE ELSE flip the switch between 0 and 180 while you are sitting in the normal listening position. You won't hear much difference if you flip the switch while standing by the sub.

In general, stay with the position which gives you the most bass.
