Ive been lurking the forum for a while now. Doing so made me feel confident to build my own home theater on a budget. Compared what is posted here, its pretty small and low budget, but it makes my 6 and 4 year old boys damn happy to play video games and watch movies in there.
The room is 12x16 feet, cinder block construction (I live in Mexico). I used Roxuls Safe N Sound insulation and sheetrock on the walls and acoustic panels on the ceiling with some spot lights.
Im using the Optoma HD 20 projector firing into the wall. The screen measures 120" when using 16:9 format.
For sound I bought the Onkyo HT-S9400THX system.
A PS-3 feeds the bluray content to the receiver.
For seating I bought a pair of sofa beds.
Here are a couple of pictures of how its right now. I still need to finish the wood trim, add some acoustical panels on the walls and finish the cabinet that will house the equipment.
