I have a Synergy F-30 system in a 7.1 format (2 F-30, 1C-20, 4 S-20). This system is working great, excellent sound etc. However I am thinking of upgrading my HT system to Dolby Atmos. This would require adding 2 to four height speakers. To complicate matters, the room where my HT is has a very high cathedral ceiling. I do have one side wall where I can mount speakers at the ceiling/wall joint, however the side is completely open. Because of this I think I will have to go with ceiling mounted amiable speakers. I would like some recommendations
