First time poster, long time lurker.
When I built my house 6+ years ago, I carved off a dedicated room in my basement for a HT. The rough dimensions of the room are 19' long x 15' 2" wide. The screen wall and left wall are both foundational walls. The room has been rough framed. The foundation wall framing is not attached to the foundation. The back wall is attached to a gym and the right wall has a mix of the stairs to the first floor and future "TBD
The foundation walls were stick framed in 2x4 and insulated already
but the back and right wall are stick framed 2x6.
I have drawn a potential layout in Chief Architect(attached).
My plans include:
135" AT screen with center channel speaker behind it.
The front 3 speakers are in wall speakers I purchased when I built the house. They are Pioneer Elite S-IW871-LR x 2 and 1 S-IW571 for the center.
I plan on offsetting the screen by a 6" wood frame offset to leave room for the speaker behind it to breath.
I will have 3 seats 10'5" away from the screen in the front row and 4 seats behind it on a 7' wide custom riser.
I have ductwork and pipes in the ceiling so I will have to create a soffit around the 2 side walls and back wall. These will be roughly 24" wide and 1' deep.
The center ceiling of the room is 114" finished height and the soffits will be 102" finished height. Of course I might be an inch or so off.
I plan on using Clips+Channel+DD+GG on all surfaces. Behind it I will insulate.
I plan on a 7.2.4 setup.
I plan on going SVS subs prob PB3000s.
I dont have an idea on the surrounds or atmos yet, budget will dictate those.
I dont have a projector yet or recent AVR.
I plan on 4k setup with 16:9 screen.
The projector will mount in the back under the soffit since my AV closet is in the Gym right behind the HT.
1) I have a lally column (in red in the picture) along the door wall. It is 8" off the rough wall. It technically is in the way of the stair to the riser. I am debating on what to do.
a) Dress it up as a finished round column.
b) Box it in as tight as possible.
c) Box it in but extend that as basically a interior wall towards the back corner of the room.
Of course whatever I do, for symmetry I was thinking of mimicking it on the other side of the room. Which option would be most helpful to acoustics? The surround speaker as of now is right behind the column.
2) Is there something glaring with the layout I need to be careful of in accordance with sound control and viewing comfort?
Yes I know very generic question. I am new to acoustical design, but can handle architectural design.
Thank you all for any help given! I am hoping to start the rough wiring in 1 or 2 months.
