comment How do I mount 20 lb speakers to drywall between studs?
I doubt my rock is damaged -- it is new. What happened is when the anchor pokes through it breaks a lot of the rock away, weakening it -- I was probably pushing too hard. You answer sounds excellent. I missed this and already finished the job...still need to mud and paint. I cut a 16"x12" hole from stud-to-stud (centers) and put in 2x4's across the top and then one vertical, down the middle. For the replacement rock I cut it 1/8" smaller to fill in the gaps with mud and when I cut the rock I left paper on the front facing side instead of using tap. Hopefully that will be OK.

I have 1/2" rock. I first tried plastic toggle anchors and then metal E-Z toggle. The plastic ones wouldn't open and the metal ones would not open or threads would not bite. I think this is partially because this is an outside wall...doh! Also on one anchor the drywall is popping out around it so I am not going to trust my speakers to this. It is time to put timber behind the walls. Any pointers would be appreciated.

I'll have to check the thickness of the drywall. I added a like to the BT77 product manual and the weight will not be a shear load like the E-Z Anchors recommend. The weight of the bracket is probably about 5 lbs. I'm worried that the top anchor may pull out. Do you have any reference showing that this will be safe?
