Ok.. Thanks John.. I am going to start with the EP500 as the only sub and make sure all is well ie: levels etc.. then add the second sub (my current energy) . I will start with both subs at the Zero position for Phase and go from there.

Acoustic Zen Adagio, Veritas center, Axiom EP500, QS8s, Anthem AVM20, MC20,Adcom GFA7400
