Great answer. I too have a different delima. I ahve the Epic 60 minus the sub, but the sub I have is from Sunfire. It is the Tru Sub Mark II. Im thinking of upgrading, from all the reviews from other websites, this was the one. Im just not getting that feeelllll, either I dont have it dialed in or my expectations are very high. I ahve been looking at the SVS line and specificaaly that same cylinder type that you have. Will that be an improvement from what I have now. I will use this system 70% HT and 30% music.
