You have a good sized room, but I agree with gs556. You may not get the best bass response.
From the review, another situation...
"Had I been able, I would have preferred sitting even farther from the speakers. At 11’, I felt as if I was looking up onto the soundstage, which manifested itself several feet above the floor. This didn’t seem at all unnatural, but I suspect that if I could have sat a little farther back from the tweeter, which is mounted 43" from the floor, the soundstage would have appeared even lower."
I liked these speakers very much when I auditioned them in a very well treated room, so with that said, if you can get a good deal it’s worth trying them.
Terrific imaging, you may need to play with position to get deep bass.
