I have a fairly cheap home theater system and while I think my system sounds decent it isn't even close to the kind of sound I experience when I go to my my local. My theater uses JBL speakers and they sounds fabulous. So is it possible for a good set of home speakers to sound as good as it does in theaters? I am considering upgrading my current system to a JBL EC35, E50s, and E30s for rears. Would this sound anywhere near as good as the theater if I added in a good sub like an SVS?
