yepimonfire, with your setting position your speakers are almost overhead at 80 degrees. With speakers directly overhead that is what I consider 90 degree placement. Putting my speakers 4 feet from my setting position makes about a 45 degree angle from my head to the speakers. 8' high ceilings is the minimum height for Atmos. Dolby spec for 2 ceiling speakers is to have them overhead as some of your Blog suggests. I have read some of your Blog, nice job.
