I'm moving into an open loft style place with 11' ceilings. There is about 3-4 feet of clearance from the right side of my couch to a wall, and the left side doesn't have a wall until the kitchen cabinets. I am going to have to ceiling mount my qs8's and the ceilin is 11' tall. Is there a certain height that I should try and drop the speakers down to? Or would a axiom mount at that height be fine ? I can mount 1 qs8 on a side wall to the right side of my couch, but prefer the symmetrical look of both side surrounds being at the same height.
