I was wondering about those balls as well. I have QS8's mounted to 5' home made oak stands. I modified the stand to accept the included "T" bracket and the speaker mounts to the front of the uprights as if they were wall mounted. They are actually quite stable. The 8's were heavier than I had expected and I thought I'd have trouble with the stands being sturdy/stable enough. The only thing I don't agree with about the QS stand is it's height.......seems too low. But, give Axiom some credit as far as knowing what they're doing!

BTW, the QS8's are fantastic!
