Yep thank you for that but I have read that white page, this is definitely a complex situation to work around. Dolby definitely tells you 45° from MPL and centered with your front bed layer. I went back and rewatched the gurus video after I read the White pages and he said in those videos that he’s basing his information off of the Dolby studio PDF not the Dolby home PDF. I’d like to get my hands on the Dolby studio PDF and read that one. Because at the end of the day don’t be built at most to be an add-on to customers within existing surround sound system as well so I wonder if they might bend some of their rules when selling retail versus to the pros. I’ll try to find the Dolby studio PDF but I have no idea where to look lol
