I listened to Salons with a friend in a room not much bigger than yours and the result was depressingly below par: poor mid-bass, anaemic bass, pronounced upper mids and hi-frequencies, unconvincing mid-range... We tried placement along the long wall and the short wall, pulled out a couple of feet from back wall. No cigar. We used Mark Lev monoblocks to drive them, maybe that was the problem -- apart from the room, of course...
Good luck!
