I did run another calibration and everything is sounding awesome. I watched the first 3 episodes of American God's last night. I'm going to figure out a way to angle them down further or even make it work with stands... somehow.

No. I did not drill into my speakers.
I have them mounted too high for that 7° tilt. Even upside down my tweeters are way over my head. The little mounts for my Deftechs were more articulate and I was able to aim the tweeters right at me (or slightly above). I'm afraid if I mount them any lower someone is gonna crack their head open walking around the corner from the hallway. I can put a stand there close to the wall, there's room, but it's a high traffic area.
