nowave, everyone here is giving you good advice on the choice b/w the m40 and the m22.
There is a bit of a trade off for bass extension with the m40 vs. a better high end clarity with the m22.
I have not heard the m40 but if they are like the m22 or m60s, the bass will be tight and clean with no rumble.
For a picture of the m22s (in a room perspective) take a look at:

The maple veneer M22s are sitting underneath a pair of QS8s beside the couch. This should give you a good idea of their size and whether you would want stands or not. Personally i would find it more convenient than putting them on the floor.
