My room is the same size as yours .
Along the same lines as Duke stated I have my positioning setup as Pryso suggests , the listening position is diagonally opposite from the speaker position . Sort of kitty corner or opposing corners . My ears are about 6 ft. from the front of the speakers . The speakers are about 6 ft. apart as well . While my soundstage is not the best that I have heard the rest of the factors are good . No base problems or dullness . I do have some room treatments in the corners and at the ceiling junctions as suggested by 8th Nerve .
Another thing that has not been addressed here is the fact that you will be in a nearfield listening situation . This will require some thought in equipment selection as well .
You will need a fairly resolving system that does well at low sound levels .
I find my Reference 3a Di Capo i's to work quite nicely for this situation with a tube amplifier .
Good luck .
