When I demoed the M22 M60 and M80 at Axiom I found the M22 + sub sounded almost the same as the M60. The only way I could tell which was on was when there was enough low frequency stuff (like in movies) for the sub to distinguish itself. On most music, the two systems sounded damned near identical.
