I am have the 5 1 2 set up. The front right, front left, center and back right back left are all mounted on the walls. Then I have two tower speakers on the floor below the mounted tv.
Sorry maybe I'm misunderstanding but
1- FR (maybe u mean surround R)
1- FL (maybe u mean surround L)
2- Tower (should be FR and FL)
*This would be considered 7.1 (not really but kinda as FR and FL should be the towers )
So I'm thinking it's not two literally above your seating area which is a different speaker for Dolby atmos
