I was talking with my distributor and we were discussing the Atmos speaker layout with a 9.2.4 system and he was told by Dolby that they changed the rear location of the ceiling speaker and it should now be placed to the left and right of the seating position instead of in the rear as shown in https://www.dolby.com/us/en/guide/speaker-setup-guides/9.1.4-overhead-speaker-setup-guide.html Does anyone have any input on this subject???
