I would have the 7 main speakers, 4 ceiling speakers and 1 subwoofer.
Atmos would sound so good I'm sure, my current setup sounds great but I would love to add 2 more ceiling speakers for Atmos.
I have the speakers ready to go for dolby atmos, I was waiting to see what receiver I want to buy . I love onkyo receivers and I own the Nr1009 now, If I win this 1030 it would be amazing!
I have watched it in 3D and i think it is excellant .
My kids and I love this story and we watch it every year and the last 2 in 3D.
It has some nice pop out 3D and the depth is great.
