Alex, I’m with the experiment if you can group. I spent about a month and a half moving mine around and found that in my room with rectangular walls in the back they sounded best in the back corners with the tweeters pointing parallel to the walls. That put them about 5 feet behind and 5 feet to the sides of the sweet spot. I’m talking night and day difference than having them on the sides or the back.
I also noticed that placing them either near the ceiling or lower on stands didn’t make much difference for movies but having them at ear level greatly improved the directional cues in video games.
