How far off the ground will they be, and what mount are you going to use? The come with a flush mount bracket for a wall, but Axiom also makes a ceiling bracket that tilts/swivels, although it is a bit expensive.

Mine are 7ft off the ground and do very well, I am using some DIY brackets I found at Menards. I'm considering getting the Omnimount 20.0 black ceiling mounts which also swivel and are half the price of the Axioms.
