I'm 99% sure I'm going to get some M22s for my study. (Got my son some M3s and I loved those.) It's a smaller room, ~14x13; so if that's not a good mix I'd be interested in hearing so.

But my real question is, is there any harm in installing them high, tilting them sideways, and angling them down? I'm really crunched for space in this room, and that would be my easist option.

One more question, I was planning on setting the crossover at 90 or 100hz, just based on the freq resp graph. But I really don't know what I'm doing, is that a good decision. (I currently have a really low end sub in this room; but I figure it's better than not using one.)
