Hi there,

I have a pair of these JBL professional control 25 speakers from 15 years ago. I want to hang them as part of a surround system but I can't seem to figure out how to do it. In the back there is the invisiball system where the ball is in the speaker itself and a big screw is sticking out. Most ones i see now its just the reverse. It looks like in the pictures that there is some sort of bracket i am missing that this screw goes into. Is there an easy solution for this? Where could i get this bracket or something similar? Whats the easiest way to get this on the wall? I dont have the hex wrench to loosen it either.

Thanks for the info Ive attached a pic.
