I'm installing in-cabinet M60's into a wall, 50 lbs each. I was going to create a shelf, or ledge, to support the 14 inches of the speaker that hangs out of the back of wall.

I'd be peeling back the dry way on the *opposite* side of the wall and build a nice ledge, using 2x6's that bolt to the wall studs, also triangulating to the same wall studs. So the weight of the M60's would not be a problem. Once I was done, I bet it'd hold a car.

BUT, what about accoustics and vibration? Would I be better off building a "stand" - where most/all of the weigth is directed vertically to a concrete floor about 3.5 feet below speaker bottom?

Your advice is much appreciated!
