Check out Omnimount, they are bound to have something. They handle everything even studio grade stuff (very heavy). Their website has only their basic lines.
A google search for Omnimount 60 will show you some of their larger wall mount brackets to handle 60 lbs speakers. I had some smaller ATC's mounted this way - works great.
G'luck.
