I have wondered the same thing - Back in May there was a pretty good topic and string on part of this subject - with several good answers from Alan. Go back to the "Technical Questions" board and look for a post from "kahlon" about "wall mounting issues on surrounds" toward the middle/end of May and see if that helps/answers your question.

Perhaps someone has experimented by setting up their QS series in the configuration you are asking about. I have not (as I don't have QS speakers (yet!)

At first thought - My guess is that it might work OK as the quadpolar design is much more forgiving of the boundry effects that would occur from corner placement. But again - the overall sound achieved is VERY room dependent!

Good Luck
