I ran mine about 3" inches away and didn't find them to be too boomy, they were also corner loaded which should have really added to the effect.

I would simply try them where you want and see if the sound is acceptable, then move them away an inch or so at a time and see if the sound changes enough to justify having them farther out from the wall.
