2.Klipsch Icon Dual 4-1/2” 2 Way Center Channel Speaker Espresso

To Add a 7.1 Setup I would imagine I would need to get two more of the following speakers below is what I am stating correct or not.

A few days ago I saw a picture that a member had that had two Klipsch's RS-42's mounted on the Ceiling which I imagine were really the speakers that were supposed to go on the side walls but instead they were mounted on the Ceiling and aming downward toward the couch I was wondring if I can do the same with my RS-52's to get 7.1 surround sound what are your thoughts on this?

Thanks In Advance For Your Replys
