If you go the bookshelf route, I would suggest the M22s for your large space. There is no particular room size limit for the speakers but you may need quite a bit more power if your new space is going to be substantially larger than your current space. If you are looking to get more than just the additional bandwidth by going to the towers I would suggest looking to the M80s. This will give you an improved overall performance and the higher output you are looking for (The M60s will do this also but to a lesser degree on the output side).
