If no subwoofer is used, the extra bass extension from a floorstander is your main benefit.
Many people here claim that, even though not identical, M22s + sub sounds very similar to M80s + sub (when crossed over at let's say 80Hz). The advantage of the towers is that you can cross them over much lower if you like their midbass better. The M80s go low enough to cover most music types, a sub adds little to it. For movies it's a different story. With the M22s, you need a sub either way as they are not full range. As for the M50s, from what I've read, they sound different than the M2s,M22s,M60s and M80s, they have a more recessed mid range, same as the M3s . Hope this helps.
