If it were me, and I didn't have a sub woofer, I'd probably leave them at full (no crossover setting). If I had a sub, I'd set the crossover to 80hz.

You can always try each setting and see what sounds the best for you. I wish receivers had a variable crossover setting from say, 40hz to 100hz in 5 or 10hz increments.

M22's would sound strained a bit at the full setting without a sub-woofer at higher volume, but I doubt that the M60 or M80 would.
