I have an Outlaw 950 pre/pro. It has the ability to set different crossovers for the mains, center and surround. My options are 40hz, 60hz, 80hz, 100hz, and 120hz. I was thinking 60hz, 100hz, and 120hz respectively for the M80s, the VP-150, and the QS-8s. This was based of the -3db points of the speakers and the fact that the center and surrounds are sealed while the ported M80s will have a greater rolloff and need to be crossed over about an octave higher than their -3db point. Am I incorrect?
