D'oh! My bad. I found the T-brackets in the bottom of the box under the packing materials. Disaster if off by a fraction of inch. I know my next problem. I'm going to try the T brackets. Got all excited when I realized that there's an attic over the bedroom (crawly space), so I can run speaker wires up there, drill some holes and drop them down to the QS8s.
Of course, I always remember the gas man in Mission Viejo who opened up the sliding panel to a crawl space, stuck his head up with a flash light to see what was going on, and got bitten in the FACE by a rattle snake. I think I'll send up Mr. Hampster first. Just kidding. True story though.
