Good afternoon. Are you looking to install the triaxial speakers on the ceilings or on the walls? If you are installing on the walls, do you have in-ceiling speakers. This would influence on suggested answers for placement for sure.
I have the installation already done, I am a Hero and you can see it on my profile.I have 4 TriAxial on the wall and 2 ceiling speakers Audio Monitor.The doubt comes to me because of the Dolby Atmos specifications, there are those who say that the rears must be 10 cms more than heard and when I see specifications of the TriAxial it puts between 50-60 cms.My next step is to change the roof ones for an Arendal, I like it recessed, but you don’t have it yet.
