Reasonably, Yes. From what I have hear about the QS line, they should make a noticable improvement as well. I actually have 4 of the CCM50's in the ceiling and disconnected the fronts when I got the Axiom gear. I see that prices are going up on Monday for the QS line, but the SVS already increased at the end of October. (after the pre-sale)
