Rob, I'd tend to agree with Randy that the 150Hz QS8 crossover is curious if you have them installed in a typical location for bass reinforcement from the room(i.e, directly against the wall and about 5-6' up). I'd try further measurements with respect to them. Edit: are you certain that all the mid-woofers in the QS8s are actually operating?
The Audyssey measurement technique which Richard references has merit. The main factor is to have the microphone positions in a tight cluster around the central listening position, possibly as little as 3" apart.
