Help! Prewire setup for 7.2. Is this good?

[Dmg]

I'm having my media room prewired and want to ensure I'm not missing anything (see attached). We plan to have a large "u" shaped couch in the room. Any suggestions/comments? I've read a lot online and this is what I've created. They originally just wired a 5.1 in ceiling which I know would be terrible.

Doesn’t look bad. I’d think the back-wall speakers should be closer together, but it looks like you have structural limitations. I’d recommend putting all the back speakers 6-7 ft. high. If they’re too low they’re too easy to localize, and that’s distracting.

How big is the screen? Depending on its size, you might need to move the seating closer to it.
