I’m with Mojo that if you can experiment with placement. I spent about two months moving mine around and adjusting the height until I proved to myself that for my tastes and room layout putting them in the back corners about a foot above ear level with the tweeters firing parallel to the back and side walls sounds the best.
Had I only followed the conventional wisdom of placing them at or near the sides I never would have discovered they could even sound more enveloping. Yes this is my personal preference, but then isn’t one advantage of HT having it your way?
