Thank you for your comments.
I apologize for not updating with details sooner. Anyway, here are some more details.
The structural details:
The back raiser
is 6ft deep running wall to wall and 14 in high from the floor. It has sand on both right and left side except in the middle where we have insulation put in. The idea is not to dampen the riser too much as I like to feel the vibration produced by the subwoofer and do not want to spend on butt-kickers (you can say a poor man's butt-kickers
), at the same time I wanted to have the ability to place the subs in the back left or right corner. We also have the step lights, one HDMI and one ethernet and the power for the front recliners supported in front of the raiser with a removable door so I can perform any maintenance.
The front stage
is 34in deep and running wall to wall. It is completely filled with sand. It supports the 3 front speakers and 2 subwoofers at this time along with the wall to wall screen. The stage is covered in the front using Fidelio velvet so it matches well with the screen frame.
is hung using channels and is double drywalled with green glue in the middle. We have the soffit run all the way around the room and internally on the left and right sides it encloses some ducts. I had the screen side soffit brought little front so it will look even once the screen is hung. Above the drywall the entire space is covered with roxul.
For the walls
, as sound containment is not of a big concern for me considering this room is in the basement and at the farthest corner of our house and all the bedrooms are on the opposite side, we went with a single layer drywall. Another main reason is I wanted to fit the screen in that room and if I had gone with double drywall then the screen won't fit.
The walls are covered from top to bottom with panels which are 1in thick filled with different type of material. For the reflection points, we have all the panels filled with linacoustics for absorption. Then for the rest of the areas as we needed some diffusion the panels are made of luan with specific holes and the back filled with roxul so it does not form a cavity. I was skeptical about this but after listening to audio after configuration it does sound real good. Having said that I really need to take some measurements to see what exactly is happening. The panels are covered with GOM fabric. The back wall is covered with 2in thick roxul to act as bass absorbers. The wall behind the screen is covered with 2in thick roxul panels with the corners covered from top to bottom with 4in thick roxul panels for bass absorption.
We have a double door
for the entry way in to the room. The doors are covered completely with panels 1in thick filled with linacoustics. The doors are really heavy now and initially I was afraid that it would rattle but they are pretty sturdy. As these are glass doors I had them put the panels over a quarter inch thick plywood and mounted the plywood on the inner side of the doors. The plywood is covered in red GOM so from the outside of the room it will look like a accented door. The door meeting point is covered with astragal. The bottom is sealed using automatic door bottom sealer. We have a closet space to the left of the screen and we had that door also covered with panels. The door is hollow core door.
The room is wired for 15.4 set up. With the traditional 11 speakers (front, center, height, wide and surround) and 4 sub for each corners (front 2 , back 2). Apart from that I have additional 4 speakers wired in the ceiling and I am hoping to use it if Dolby Atmos comes to the home theater arena. Mainly I have it defined for the "God" speaker concept that Auro 3d has. Obviously it is just an assumption and need to wait and see how it will turn out in the future.
Now to the equipments:
The mains are canton ergo 690 DC.
The center is Canton Ergo 655 DC.
The surrounds are Klipsch RS52. (4 of them)
The wide speakers are Ergo 601
No height speakers yet.

Front row - around 13 ft from screen.
Back row - around 16 ft from screen.
I have let the lens in place for all as I like it that way. The projector is bright enough for me and it fills the screen very well. As the room is really dark the brightness is pretty good. Just incase I got additional 2 lamps for the projector so in case after it hits 1000hrs the output is not that good I can change it. We have already used around 400 hrs
I will upload some pictures later. Please let me know if any other detail is required.
