You’ll also have a rather significant moment force on that wall.

We recently mounted a pair of 85’s in a bar. The architect’s idea was that the wimpy metal studs would support the pullout arm mounted TV’s. We convinced the GC to add some plywood, but his idea was to add a couple small pads for each TV and they were poorly located.

Fortunately, there were no depth issues and we could add a full plywood base, spanning multiple studs, behind each set.
