There's such a huge range in what people consider "reasonable" sound levels that it's hard to give good advice. My primary music speakers are M40s, which are basically tower M3s, in what amounts to a 20x40 room with cathedral ceiling.

They can easily play quite a bit louder than I would normally want without any stress -- but if I crank them up for that "wall of sound" they are instantly and clearly not up to the task.

If you're looking for "pleasant" listening levels I think a couple of M3s on the wall would be fine. If you need to crank the volume then IMO M22s plus sub aren't going to be "better enough" to justify the cost & complexity.
