Double layers of drywall finished with greenglue between. All outlets boxes have puddy behind them, soundproofing done thanks to Jeff.
This will be the riser, it will also serve as a bass trap!
The riser is 10" high and 12' wide. The step is 30" wide, 11" deep and 5"high. To the right of the step there will be a jack for USB, HDMI, and Ethernet that will run via the pipe into the media room, which has not been cut yet but it will be all the way in the back of the room.
I have copied Mario's design (Cinemar) with his blessings of course. The design is far from done but it's coming along.
I have run a 2" pipe throughout the room and also into the main feed in the house so no wireless. Everything will be hard-wired.
Will be shopping for projector, screen, and seats this week.
