There is nothing about your room size that would prevent them from sounding good. You will have to treat some of the weaknesses though. That may sound daunting at the outset, but remember it is cheaper to treat a room than it is to buy new speakers, and room treatments will outlast most componants (they way many people go through gear here) whether speakers or electronics, and they can make a huge difference in the systems sound quality.
The room should be done anyway. So buy the Quads (which I have heard and thought they sounded very good) fix the room a little and enjoy some beautiful music.
