It's finally time to start my first theater build. I've been in the house for 15 years but have never had the time/money at the same time to get the basement finished.
I'm looking for some productive input from all of the experience in this forum to help me maximize my space. Here are some basics on what I have in mind so far:
The space is currently unfinished. 9' ceilings throughout the basement with what will need to be a soffit on one end. I plan on trying to do a "room within a room" so my ceilings will be lower. I want to minimize the sound leaking out of the theater as much as possible.
I have 15' x 12-14' to work with so I know it is going to be a relatively small theater. The house is a walkout (no windows on the end of the basement where the theater will go, I always intended to build one and had the house built without windows in that area). I have one wall that is concrete and the floors are concrete.
Right now, my early plan is to install XPS on the concrete wall and build my 2x4 wall inside that. I intend to use Roxul in all the walls and ceiling and double drywall with green glue and acoustic drywall as the second layer. On the one wall that the theater will share with the rest of the basement, I will build a second wall and am considering using a double exterior door setup.
One wall (probably the front of the theater) will have a storage space behind it where I intend to put all of the equipment. Most of the equipment is TBD
I have two projectors that I plan on installing in the space. For movies and TV, I'm planning on using an Electrohome 8500 CRT. I have an inexpensive Sharp DLP that will go in there too so my kids can play videogames without me worrying about burn in. I'm sure some will question the massive CRT, but I do like the picture and until the true 4k digitals come down from the stratosphere, that's what I'm going with.
I attached my simple drawing of the space.
Now that I have that out of the way, here are the questions I have before I start buying materials:
Any thoughts on the XPS on the walls before I start the stud walls?
For my "room within the room" should I plan on creating a ceiling through setting the lumber across on top of the walls or build the walls a little higher and use hangers from the top plate?
2x4 or 2x6 for the ceiling?
Attaching the walls to the concrete floor - should they be placed on something to isolate them from the floor?
Inside the theater, I'm planning on using the Dricore R+ for the floor and build a riser on that.
I've tried to dig around the forum to get as much as possible before I threw this out - I'm trying not to ask questions that have been answered dozens of times before but forgive me if some snuck in.
I'm really excited about getting started on my little theater and look forward to input!
