I've read through this entire thread... it was lengthy, spanning a few years lol
So, here's my situation, bought a new house--has metal studs, or concrete exterior block construction for the exterior. I need to mount a 6010 pioneer on one of those walls. If I do it on the exterior--Cutting out block, will not be fun to run the wires, or going up to the attic for the speaker wires. If I do the metal studs, I can probably span 3 studs--vmp3 sanus (not positve the model is right)--extending one. I worry that even 3 studs using 6 toggle bolts wont be enough to support it.
I was thinking I'd be best ripping out some sheetrock and putting in woodstuds (at least 2) to make sure it's supported properly.
Same problem with 42" and 50" plasmas in the other rooms.
