15' x22' theatre room build

hello everyone I recently sold my house where we built this small family theatre room 12 x 15 x 8'6"

https://www.avsforum.com/forum/19-de...tre-build.html

and now I am on to designing my next theatre room it will be 15' 2" X 22' X 9' 4" with an AV closet on the side it will be a dedicated theatre room with a projection screen

we truly got sucked into the theatre room experience and want to make this nice and comfortable. we liked the couch sectional and are thinking of two rows of seats this time but I am not sure if the couch goes on the side, goes in the back or goes in the front...any body have any insights or pictures they would care to share of their similarly sized theatre rooms. thanks bob

In a serious two row theater you don't sit along the side or back walls. The sound sucks. The rooms standing waves peak at the room boundaries and the bass will be boomy. You will also be too close to the surround speakers.

You also don't want to sit at a 90 degree angle to the screen for a 2 hour movie unless you have a good chiropractor on call.

thanks Jeff,

I did some preliminary measurements using the Seat craft rialto back row chairs and there modular sofa.


with 4 row seating I can get easily off the walls by a minimum of 18" on the right side and back wall and then about 3' off of the left side aisle for walking.

the seating will be directly in front and facing the screen.

this is the style I was thinking of, sofa up front and row of seats in the back open link and click on first picture

if I need to be further off the walls I suppose I could use a three row back seat and a smaller front sofa.


is there a good minimum distance off the side walls?

thanks bob

My theater size is very similar (just a hair larger) to what your new room will be. Has 2 rows and 125" wide screen. Link is in my signature The Force Theater

Jedi1982, thanks that is an incredible build and gave me lots of ideas, my previous build was a lot fun to use but really just a dedicated room with good equipment and a sofa in it. your build has me thinking about how much more this next build could be, I know we will be using a sofa up front and back row seats. I will be PMing you with questions. thanks for helping out. Bob

Like many have said and you probably know from your previous build, plan, plan and plan. With a solid plan and dimensions it takes a lot of the decisions as you go out and you can focus on the work. My theater is 15-6 x 24 x 10, 7.3.4 and a 150" diag; so right in the same neighborhood as you. As big said STAY OFF THE WALLS. Terrible sound, terrible view.


I went with 6 individual seats centered with walk paths/stairs on both sides. All speakers in wall (with back boxes) and an AT screen. 3 mid-grade subs with a miniDSP has worked great. I've attached an early draft of my theater. Ultimately things changed a little before we started. But 2 rows of 3 has worked perfectly for sight lines and sound (18 inch riser in the rear to meet the door (concrete basement floor dropped in this area during construction exactly for this purpose).


good luck

Seems like you'll have a nice space to build in. Looking forward to seeing it.

I think Tedd has said 3 ft in the past to others but you'd have to double check with him.
