I have a few questions about my first theatre (screen size, and speaker placement)

To the right of the screen (as it currently is located) is an existing utility closet which Im going to use for housing equipment (receiver, server, media pc, etc). I'm planning on moving my gym (which is in the proposed theatre now) to the space behind the back wall.


Unfortunately the previous owner had done some work which includes a bathroom which is behind the right wall so I don't have as much flexibility.


Here is a new image with the false front including a 120 inch screen and for fun my klipsch rf 82's. It will also accommodate my subs. Now all i have to do is figure out how to make the front acoustically transparent

I'm open to placement for the sectional. Im guessing that the primary viewing position will be about 13 feet from the screen.


In terms of screen size it will be 16x9.

I made it constant image area 2.0:1 so over all it is 126"x65" that gives me

126"x52" 2.40:1 with 136" diag, 6 12" bars top and bottom

126"x54" 2.35:1 with 137" diag, 5 1/2" bars top and bottom

120"x65" 1.85:1 with 137" diag, (man this size make it like being there) 3" bars both sides

116"x65" 16x9 with 133" diag. 5" bars both sides

So in the way the best of both worlds If I would have done a 2.40:1 screen 126" wide my 16x9 size would have been 92"x52" with 106" diag. If I would have done 16X9 65" tall my 2.40:1 would have been 116"x48" 126" diag.

I was actually planning on using IR repeaters and closing the closet off (if i knock out the back of the wall in the closet it becomes accessible via my utility room). I will then run conduit around the room and to the projector mount point for all of my wiring needs (any exit points properly wrapped to isolate them).


One thing i just realized is that the gym area could potentially introduce a triple leaf wall based on my extremely limited (but growing) understanding of sound proofing. My plan is to use clips and hat channels with two layers in the theatre room. Given that the back wall as currently illustrated will be finished on the other side with one layer of drywall fixed to the studs will I be introducing a third leaf, or will the clips and hat channels eliminate that potential?

Triple leaf is if you would have left the drywall in your theater put the clips and hat channel on top of that then added the two layers of DW/GG/DW. If you are ripping out to the studs and putting the clips and channel on the studs you just put the R13 in there and then it is not triple leaf. Make sure you add the putty pads to any receptacles the new exercise room or any other adjoining room or hall may have. You will also have to sound proof the utility closet if it accesses the theater. Otherwise your efforts are in vain. That is why mine is just outside my door in its own media closet. I just use the Denon remote App on my phone to control sound and the blue ray player. You also have to give some thought once you build your sound envelope where the lighting and receptacles will be. Most myself included try to run them in the soffits columns stage and riser. Since you will not have any of that then you will need backer boxes for the lights and something else for the receptacles. Have you gotten with Sound proofing Company to discuss the best way to decouple the bulk head?

I was generalizing a bit in terms of the bulkhead Its a collection of ducts, gas lines, water, and one of the i beams for the house. I was planning on having it framed around which will result in a bulkhead noted in the drawings. attached is a quick pick.

I was just going to be lazy and frame around it, but as I read more and more you are probably right. I do have a cousin who runs an HVAC company so there are really no excuses. Thanks for the push in the right direction.


Someone else messaged me noting the window. I plan on closing it off completely.


I have been thinking a bit more about flipping the orientation of the room. One thing i have to keep in mind is that the location of the door is non negotiable (there is a finished bathroom to the left of it if you are exiting the room and then a staircase to the left). I was planning on using a solid core door (with gaskets) and my only worry is that if i flip the orientation of the room the door will be close to the mains and create a sound issue which in the current orientation is easier to manage. I might be way off on this so feedback would be appreciated.


I'm also curious if (given the room dimensions) if a stage would be needed. I currently have a subfloor installed (dricore) which i plan on carpeting (heavy under pad and thick pile carpet). Would that be sufficient with diminishing returns from a stage or is this something that i shouldn't skip on?


Thanks to everyone so far who has PM'd me and responded to the thread. It is very much appreciated.
