Lots of progress in The Plains Theater! It doesn't look like much, but I promise, it was a lot of effort! I'm trying to get all the loose ends tied up before the drywall gets hung. Without further ado, here's the pictures:
I mounted some 5/8" plywood to the ceiling where I "think" my projector will go. I also built some backer boxes for the receptacle and LV box in the event that I guessed right for PJ location. This will be drywalled over until I actually get ready to mount my PJ
The joints on the DW inside the boxes are not that great, but I'm planning to pack it full of putty pads if I actually use these openings.
Next on the agenda was building my dead vents. These took a LOT longer than I expected. Here's a refresher on how my room is laid out with respect to my vents.
I started with the return (shown near the bottom of the above render). I also decided to go through the wall rather than the ceiling. Here's a before shot of my equipment room. The theater is on the right of in the below image:
Here's a shot after the drywall started. I've got DD+GG on the wall next to the theater, 1/2" on the ceiling and remaining walls, then I put down DD+GG just in the area where my dead vent will go (including the floor). Here you can see I've started framing out the two sections:
Here I've almost finished the transition/plenum going into the room. I had lots of clever ideas for how to build this using much less lumber, but I decided it would be quicker just to Rube Goldberg the thing. I ended up with a box that's way over built, but it was quicker this way.
This is the transition into the room. I don't have space for an 8" pipe to fit into my soffit, so I decided to use the wall cavity. I used DD+GG to make a vent that I will seal against the back of my drywall with some acoustic caulk. I left about 1/4"-1/2" gap between the vent and where my first layer of drywall will be. I'm hoping this will limit the sound escaping through this opening.
Plenum closed and duct connected. Here you can see that there are two sections to the dead vent. The first just holds the ductwork, the second will house my fan so that I can add an access panel.
First section all sealed up with DD+GG and all the remaining drywall finished in the room. I'm not too happy with where my rack had to go. It's a tight fit to get between it and the wall now, but it is what it is. Once I get the electrical and relaying for my fan worked out, I will add the DD+GG on the second section to enclose the fan.
Starting the supply side dead vent. This is just a DD+GG box that will house my supply. Here you can see the existing 10" supply that I tapped into with my 8" supplying the theater.
Duct added with insulation.
Finished dead vent:
I did something similar with the entry into the theater here. I built a transition from the dead vent to the theater using DD+GG. I won't be able to caulk the gap between the transition and the first layer of DW, but it should still help with the sound leakage. I stubbed out a piece of 8" rigid duct that my flex is connected to in my vent, and I will connect onto it inside the theater.
I believe I'm ready for drywall in the theater now. I need to add the odd piece of insulation here and there, but I can do that the day of if I have to. I'm excited about the prospect of getting the room in drywall.
Now I need to find a relay that I can use to trigger my return fan when my PJ or AVR (that I don't have yet) turns on. Any suggestions? With all these words, I wouldn't blame you if you didn't make it this far
