Mike,
You will have to experiment. My hunch is that you will probably be OK with them pulled out 35" from the back wall to the rear of the speaker, especially considering you will have 6 feet on the sides (vs. my 36" to the side wall). However, I can't emphasize enough that room treatments made a considerable difference in my room... and I never felt the need for room treatments prior to owning the C4 (previous speakers were the C2 & 1.3SE's).
What are the dimensions of your room?
