Yea, I meant the rears. I'm very new to all this, so thanks for being so patient with me.
I would love for all of the speakers to be in-wall so that they are somewhat hidden and so that my kids don't mess with them
So for the surround rears, I'm assuming I would put them to the side, slightly behind the couch, but angled toward the MLP?
As for 5.1 vs 7.1, I suspect 5.1 would suffice. I would definitely want atmos, so I could do 5.1.2 or 5.1.4, but unclear if those additional speakers will provide that much benefit.
