Thank you gentlemen for your replies...
I did check out the Axiom brackets which are very nice but they do not meet my needs. I guess a little more information is necessary...
The area where the speakers will reside is in a 5' x 10' extenion of our house. On the left is a 36 x 60" window, in the middle is an 84 x 60" window, and on the right is the higher traffic entrance door.
Because of the configuration of the room, the outside three walls (covering the windows and the door) will have curtains leaving the best location to mount the speakers being the corners... The Axiom speaker brackets are just not deep enough.
Cheers
