KC, I think the "depth" issue is somewhat room dependant. In my case, I could not hear any difference beyond maybe 10~12" out from the wall if that helps.

Maybe someone official can chime in here, but my gut feeling is that the distance from the wall is mostly relevant to the mid to lower bass region and maybe the use or lack of a sub (along with your crossover freq) might be an issue as well??
