The M22 is a pretty beefy bookshelf speaker, and it's rated down to 60Hz at -3dB. When paired with bass management and a sub like the LFM-1, the end result should be easy to blend together and give both good music performance (without the sub calling undue attention to itself) and some serious fun on movies.

The M60 by itself would run out of steam in the mid-30Hz range (37Hz is the -3dB point) and it won't have the same authority at low frequencies as the LFM-1. Plus moving those low frequency duties to a powered sub will take some burden off the receiver, allowing it to put more into the higher frequencies. I've run both with and without a sub (using floorstanding mains with comparable reach to the M60's), and I think your idea of M22+LFM-1 is likely to be a better overall system.
