It's a fairly small room. Is that bench where your seating position is, or is there a couch or something in front of that?

That said, I sit about 8-10' away from my M80s in a room that's 19x20 with an opening to the kitchen behind it, and they sound just fine. As long as you calibrate things, you're ok. Of course, if you're too, too close to the M80s (like, with 2 feet) you start hearing individual drivers instead of the whole thing.

I am the Doctor, and THIS... is my SPOON!
