My room is 18x12x9 and I'm happy with the M22tis'. That being said, I don't know if I would put the M22 in a room much larger than mine depending on your listening habits. When I push my system hard it is very loud and crystal clear but you get a sense it is reaching its "ceiling." I have considered "updrading" to M80s although this is more looking ahead to our next house with a larger, dedicated room.
