I really am interested in the epic 80 system. It really sounds like a incredible value. What I dont like is the fact that the M80 towers' frequency response goes down to 28hrz and the sub is above that at 30 or something. A true sub should to me at least go down to 20hrz. Anything in the future to appease my bass crave? Why should this sub be good enough for my LFE effects. A good response and my order is in. The only thing I dont want to here is lack of availability of deep bass material because I have plenty.
