Home entertainment set-up (HELP)

Because of the lovely people in this subreddit, I purchased the Samsung Q930B surround sound set last week. Next week we're moving into our new place so we're looking for installation recommendation.

​

So any advice/recommendations on how to set up the rear speakers on the Q930B? We're thinking about mounting the rear speakers with a downward titled about 8 feet up the wall and 2 feet behind the viewing position? Our ceilings are about 10 feet tall. Is this option better compared to having 2 speaker stands for the rears behind the couch?

Would love to know how folks think about this option.

Thanks a ton in advance! 😊
