..sorry guys, I was away for a bit. I have not had a chance to take pictures yet but to me it feels like the issue is not over powering M60s, but more like blending of my EP350 with my M60s. I think the sub is fairly balanced when it comes to music (though I have to have it at like 3 o'clock volume rather than 12 o'clock) but for movies my sub seems to be not fully blended in with my mains. It seems to be in a little bit of a "world of its own". I have tried playing with the phase, I will change cross over to 60hz today and see if that helps. Do you guys think it is a good idea to change mains to 'large' if I change x-over to 60Hz?
