The global crossover is a problem I'm going to face too. Even worse, the next step below 80 Hz is 50. That's too low for the QS8s, and probably a touch too low for the VP150 also. I figure I'll keep it at 80 Hz, and just set the M80s to Large (or Plus). Movies will still get all the LFE going to the sub, but I'm worried about some of the electronic music I listen to which I'm sure has infrasonic components. Hopefully I can position the sub so that the Plus setting doesn't cancel out more bass than it adds; as it seems to do right now.
