Need information on Polk Monitor 30 speakers please

[Old Geezer]

I just purchased a surround sound system and chose the Polk 30's for my surround speakers. (I have Polk 50's for L/R; Polk CS1 center; and Polk SW10 sub) Nothing great I realize but should be a good enough for an "old geezer"

While waiting for the speakers to arrive I'm in the process of running wiring and I can't seem to find a picture of the back of a Polk 30 speaker. My question - Where is the placement of the keyhole bracket for wall mounting and also the placement of the 5-way binding posts? Thanks for any help. I'm off to church and I'll check back later.
