I have the QS4's,and I hung them to the wall using the brackets that came with the speakers,and No screws came with them. Don't use nails, I used 1 1/2 inch drywall screws.If you can't screw into a stud behind your wall,than you might want to use plug ancures with your screws. Also Ian suggested in one of his posts,for the best placement for Axiom surrounds is behind the seating area on the back wall, 1 foot from ceiling. I went 1 1/2 feet from top instead,for appearence with the room and they sound great.
