**UPDATE: Getting very close to completion. New pictures posted on Page 2.
I've been a long time lurker on this forum but this is the first time I've had an opportunity to build a decent theater. I realize this is very modest compared to some of your amazing theaters - I strive for greatness someday, but I only plan on being in this house for a couple more years
We moved into this house last July and I'm now working on finishing the basement. I've attached some floor plan pictures from floorplanner - the theater room is 13x19 and I've decided to keep it open to the rest of the basement. I came to this decision mostly for resale value, but also because I like the feeling of having the open space when I'm just casually watching or playing video games, etc. I am undecided if I will do a tiered seating setup, but most likely I will just keep the single row.
With that being said, now that the framing is up and I've had a chance to mock up the screen and speaker locations, I'm wondering if it would be wise to close in the back area of the theater room. There is currently a 24" wide column that houses a support beam and my left side surround speaker. In positioning my sofa for an ideal viewing distance (135" 2.39:1 screen) I discovered the side surrounds are slightly in front of our heads, and I think they sound better slightly behind as recommended by Dolby, etc. I've considered making the column wider so I can move the speaker back, but at that point it seems like it might be more logical to just enclose the entire opening with a wall.
Can you look at these pictures and tell me what you would recommend? I'm wondering if having it enclosed would benefit my acoustics at all, specifically the subwoofer and surround speakers. I plan on upgrading the sub to something fairly beefy as I realize I have the entire basement area to pressurize, but I'm wondering if having the room "less open" will make any difference in that regard? Also in terms of maximizing my surround field, would having it boxed in have any impact? I do plan on hanging DIY acoustic panels to take care of reflection points.
I'm also open to any other suggestions or comments. I'm at the point where I'm ready for drywall to go up but I'm second-guessing myself about a lot of things.. I want it to be perfect when I'm done!
Looking into the back of the theater. I'm still experimenting with the surround height and location:
This is the wall in question:
From the back of the theater. Hard to see, but I had a soffit framed around the screen area. My temporary screen is just primed drywall, but I have a 135" Jamestown 2.39:1 screen waiting to go up.
Closer view of the soffit, which will eventually house 3 can lights:
