Jim, the roars on the M2(or similar)would blow you right out of the room. More seriously, that type of speaker has plenty of dynamic capacity for a center channel in all but the largest of rooms, probably quite comparable in that respect to a VP100. If some center channel material would somehow be too much for the center speaker, regardless of how big it is, shut it off and let the mains handle it.
