Thanks guys, that's just not what I wanted to hear

My rear speakers are Paradigm Reference 40's and IF I do the sides they will be some 'on the cheap' in-walls for like $300. I wouldn't mind that if the sides were just for ambience and not heavily used, but if they are the main surrounds I'd rather let the 40's do that.

I've got some thinking to do now, I'd hate NOT to go ahead with the side inwalls since it's a new construction and wish I had them later.
