I'm sure you are as excited as I am, I just ordered my system jan 2nd. 2xM60s, 1xVP150s, 1xEP500 and 2xQS8s.
I asked a similar question on the QS8s and axiom and this board say they are very forgiving. I will set mine about 2 feet about ear level but am forced to put them just infront of ear level rather than just behind. The alternative was about 7 feet behind. My room is 13 feet wide with a 13 foot left wall and a 30 foot right wall. I will have a sony Wega 60" rather than a screen, so based on furniture etc, the QS8s will be just in front of my ears (within a foot or less).
So from what I here these QS8s are very superior surrounds and the placement is not as crutial as other surrounds.
I will find out in about 6 weeks, when my basement is all finished and system set up.
