Axiom Home Page Forums General Discussion Home Theater Phase setting when using 2 subs ?

I will be receiving my EP500 in a few days and adding it to my current setup which contains an Energy 10" sub. I will place the EP500 where my current sub is, being my listening position, and the 10" sub in the front, diagonally accross from the other sub. Question is: do I have to adjust the phase setting on the EP500 to 180 ? because I have 2 subs ?

For those with 2 subs, how did you set the phase, or other settings on the EP500 ?
