Hello rotipom

Very interesting question! There are very few full range speakers out there, and real full rangers are very expensive! Considering the size of your room, I think a very nice subwoofer would go very well with a pair of M22s and if you're able to integrate these speakers, you'll have a very good approximation of a great pair of full range speakers.
