Well, those specs sure beat my cheap Denon. I'll bet dollars to donuts you won't have a problem.

I'm in a 4,000 cubic foot room (10% smaller than yours), I sit 8 feet away from the M80s and I listen to music with a half watt per side. At this level, my average SPL is 75dB. When I turn on my 600, the average level is 85dB.

For movies, I'm a bit more adventurous and pump it to a few watts per side .
