I'm glad I don't have that kind of wizardry with Rotel (I'm not knocking it; I'm sure Rotel didn't want to pay the licensing, and perhaps that savings made my pre/pro a better "value" -- I'm certainly not missing it).

Question: For those with M22s, do you use 60 Hz as a crossover? I do feel my M80s and VP180 work well at 40 Hz, and I like the idea of having a difference no greater than 20 Hz in the handling range of the fronts vs. rears (maybe that's a silly notion). So I'm going with a crossover of either 60 front/80 rear or 40 front/60 rear, but maybe M22s are just ideally suited for the tried and proven default of 80 Hz.
