The rear wall of my Home Theater is really a folding retractable partition. The only way I can mount my QS4s for the rear center is either from the ceiling or use a speaker stand. My QS4 side surrounds are mounted about 3 feet above the sitting position or about 6 feet from the floor. I could use the AXIOM QS4 speaker stands for the rear center surrounds, but the maximum height is 36 inches. Any suggestions?
