My first try to build a HT room, took me about 2.5 month.
Had to build 2 complete outer walls, and 2 new inner walls.
The screen is 12' wide, 2.40:1 aspect ratio, the walls are drywall on top of hollow blocks.
The screen wall and stage is covered with the black material used for staffed toys. It absorb any light, even the flash from the digicam I used to make the pictures.
I could not get a good quality black velvet, so I tried this soft material, and its just perfect.
The screen itself is made with blackout clothes, the better and more expensive one, from shell canvas.
Under the carpet are tiles. On top the them is foam followed by the carpet itself.
In the corners where the screen is are bass traps, and on the walls some sound absorber or however you call it. All made with rockwool and installed at the reflection points.
Frequency tests showed that no vibration anywhere occur anywhere in the room.
The aircon is installed in another room, connected to a homemade duct (the frame you see on the backwall in the first picture is the return air). And it cools the rooms down to 18C if I want and is so quiet that I sometimes forgot to turn the aircon off (until the Veco reminds me...).
I use a Panasonic AX100, in combination with a PS3 for the HD content, streamed from a PC, and the amp is Onkyo TX-SR606, 7.1 setup.
The only thing I do not like are the chairs, because I also build them completely, and so they look... hehe
Anyway, sound and picture are perfectly fine for me. Hope it will be even better when I will upgrade to a 1080p projector in the near future.
