Hi there, First time poster. Planning out an upgrade to add Atmos to my existing home theater. I already have a solid 7.1 setup and a receiver that can do 7.1.2. I'm trying to figure out what speakers to by for the ceiling channels. My fronts are Martin Logan (motion 40s and a 30 center). Running polk rti bookshelves in the back at the moment. I was looking at the Martin Logan Helos 12, or the electromotion IC models, but I'm not finding much info on anyone using them for Atmos specifically. I'd prefer to go with the Helos to save some cash, but I want to make sure they're going to measure up. Would love to get any advice you have!
