I've had the same Yamaha sub for about 5 years now so this is new to me. I got a Energy S12.3 to replace my Yamaha and it has a knob on the back for phase control. The range is from -180 to +180- degrees. I have no clue what this means and I dont want to spend all night doing research(I know I'm being lazy). Basically the manual says this is to adjust the phase of the sub so it fully intergrates with my system.

Is there a certain way to set this up?

I assume I'm supposed to play by ear and start at -180, play the same piece over and over and make small adjustments until I think it sounds right. Any advice will be helpful. Thanks in advance
