I am wondering if anyone has these speakers mounted to a ceiling bracket? I did some research and found two companies, Vantage Point and Peerless that make speaker mounts that support up to 25 pounds. I believe one Rti6 is 20 pounds, but I'm not sure. I've seen photos of the rear of an Rti6 and it only has 1 key hole slot to mount them on the wall, but what about a ceiling bracket?
