While doing some research on articulating mounts (the wife doesn't like the bulkyness and how it sticks out from the wall) I was told about a "in wall box". This essentially fits in the wall between 32" studs. As a result the center stud needs to be cut. The articulating mount then fits inside of the box essentially hiding the bulkyness of the unit while still allowing for you to pull it out and move it around.
Looks great but my question is does anyone have experience with these?
