Surround speakers
RMA,
Read one of the Dolby speaker setup articles and adapt for your room. The surrounds are normally 2-3' above the listening position. The (Main) Surrounds are on the sides of the listening position and Suround Backs are behind the listening position.
The Axiom QS type speakers are a quad pole designe to provide a disperse surround field. You don't have to point them directly at the listener and they should be more forgiving with placement. For ease of wiring and mounting I would utilize the keyhole slots to hang each speaker on the appropriate wall. You should use a drywall anchor if you are not mounting to a stud location.
