You can have the Axiom stands custom made, I am not sure if that means they could be higher if so desired, never looked into it. I have heard a set of QS8s on the Axiom stands over at icehawk's place and the surround soundstage was as good if not better than my system which has the surrounds ~4ft above the listening area due to room demands and being cautious.
