Desc: This will be the screen wall there is a lot of work to do. You can see the electrical boxes for the speakers. The building has access below the floor so all the low voltage wiring is just a piece of conduit stubbed out below the floor.
If you are asking why the electrical boxes so close the floor there is a good reason. We were planning a nine foot ceiling. Building code restricted the height of the building which limited ceiling height. So now the plan is to drop the floor down 12 inches.
