Spoke to someone from Axiom today regarding trading my QS8’s for M3 in walls to get 5.1.4 going. She said there was no need...to keep my QS8’s and that they would work just as well as direct firing rears.

I did end up getting four M3’s for my heights. But I’m concerned about the rears. It goes against what Dolby says regarding proper speakers for Atmos.

Will using the QS8’s be a less optimal setup?

Also my back wall is maybe four feet from the listening area. Is that too close to put the QS8’s at ear level?
