As much as I like the center channel mounting solution that David F has posted in the forum, the wall behind my plasma is solid brick, and actually backs up to an elevator shaft, so there are random metal plates intermixed with the bricks.
The tv stand that my plasma is sitting on has a shelf underneath the tv that is plenty large enough for the 340C that I have on the way. I plan to get more sorbothane to place under the speaker to isolate it, but I would like to angle it up. It will only be about 8 inches off the floor, so it would be nice to angle it a bit (since seating is about 10 feet back, it won't need to be angled too much).
Has anyone found a good solution for doing this (foam wedges etc)? Or am I best off just trying to prop it up with layers of sorbothane or something?
