Ok update time. Well everyone was right about the Velcro strips. Seemed to be a really solid strong hold to the wall but after about 12 hours down came the right Atmos speaker.
To my surprise and to Polk's credit the speaker was not damaged at all! Not a freaking scratch. This speaker is solid. I am so impressed with Polk at the moment. Not broken, not even scratched, sound is just fine.
So that experiment was a fail. Today I went out and bought a cheap 10 dollar Stud finder at Walmart. Borrowed my father in laws drill, got the old ruler out and they are up on the wall the correct way. All is good in the end.
Yes, I'm a big dummy.
