Ryan, welcome. I'm also of the view that in a 5.1 setup the surrounds should be QSs. These are side surrounds in a 5.1 setup, not "rears" and should be about 6' up on the side walls and slightly(maybe 2')farther back than directly to the side of the listening position, to give a little more back imaging in the absence of actual back speakers. Don't know why you suggested "directly behind me".

Enjoy the music, not the equipment.
