room space

One thing that would concern me is the height of the 3.3's woofers in that size room. When there are two woofers and their dimensions from the floor are approximately the same as the distance from the side walls, that tends to throw off the in-room response in the upper bass and into the midrange. 

There's a big difference between reading about something in a magazine or sales brochure (white paper) and doing it for real. 

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.
