Nick in my experience placement theory is just that “theory.” If you have no choice but to follow it you will get something good, but if there is any way to wait until you have things set up and then experiment a bit with your placement options you are assured to get what sounds best to you.
Case in point, in my apartment I experimented with various positions and found that corner loading (something we’re told you never do) my 5.1 QS8s with the tweeters firing down each wall was the best rear and side soundstage I’ve ever had. Better even than 7.1 in that same room and my present room.
Just my 2 cents.
