Since one wall of your room isn't really a wall, but an opening into a much larger room, I wouldn't consider your room to be small. Much depends on the layout of the speakers and your listening position in the 11x11 area where the system will reside.
how big a speaker can you put in an 11 x 11 room?
the ceiling is 8 ft but a side wall has a 6ft opening to a 25 x 15 living room. the speakers would be in the 11 x 11 room. I like the Elipsas though the bass seems as though it may be too heavy in a room this size.....same for the Revel Salon2s.....i listen to jazz vinyl through Mac electronics.....
