design by Mike Major at gik. Built by me and a couple of my former employees and friends. Modular room i can take apart and put back together in another home.
14'4" X 18'6" outer shell
Side walls are 10 inches thick with insulation and covered in speaker fabric and slatted wood slats with specific spacing above 2 feet which gets tighter from front to back.
Rear wall is 18 inches thick with built-in corners a bit thicker stuffed with insulation cover with fabric and slats and gik diffuser
All exterior is double sheet rock plus front wall also has 1/2" coated birch which is what the slats are but slats are 1/4"
Then I put a Daikin mini split in that only runs at either 14 or 16 db. Can't remember but it's dead quite in here.
Theater seats are palliser electric recliner very nice. Bought show room set as its now discontinued and got them dirt cheap
