M22 and dual EP500s would be virtually identical as M80/EP500 for movies, you might get more 'feel' from the mid/upper bass from the M80s same goes for music. The EP400 plays low enough but lacks enough SPL to make much difference with the M80s playing, at least with my experience I had with a single EP400 and M80s dual 400s might work better.
