Hey friends, I need some help to get the right Atmos speakers for my living room. Since the room has a half vaulted (4:12) ceiling, I think I need some pivotable in-ceiling speakers. A salesman told me that the CDT-5800-C II is being discontinued, and recommended me the Pro-180RPC model. However, I cannot find anywhere to confirm that the Pro-180RPC model is pivotable. Can anyone confirm it? I did notice that the PRO-18RC model is pivotable. What is your recommendation over the CDT-5800-C II, PRO-18RC, and Pro-180RPC (if it's pivotable)? Or any other suggestions? Please, let me know all your suggestions! Thank you very much!
