Room in a room build

You should be fine. Just pointing it out here for anyone else watching that you could achieve the same thing by using flexduct with three 90° bends and run it up in the attic. Sound doesn’t like to go around corners.

I hope when all is said and done, you will like the sound of your drums. Seems to me, just guessing, the room will kill all resonance or echo.

Stay tuned. When the basic room is all done, it will be smooth bare walls all around. When the room was like that before, it was unbearably echo-y. I put some minimal treatments up on the wall and was happy with how it sounded. That said, I don't have a very refined ear, so as long as it's not on the extremes (totally dead or echo chamber) I'll probably be happy enough.

Got the MDF (outer) layer up on the inside room, and part of the 5/8" drywall (with green glue in between), including ceiling. Boxes are sealed up and HVAC system functional. Drywall should get mostly or all done tomorrow, then we'll be waiting on doors and windows.

Finished interior layer of drywall, texture and install of windows. Windows are super heavy laminated pane glass. We decided to cover the gap between inner and outer wall with a self adhesive mass loaded vinyl product normally used to sound dead cars. We did this for looks and to keep insulation particles from getting from the air gap area into the room (or between windows, which is inaccessible). The product is flexible, so will maintain acoustic isolation between inner and outer walls.

Here's the window opening with just the material across the gap. This and everything else between the windows was painted flat black for looks.



Here it is with the two panes in place.



A view of the other side.



Now we are just waiting on some door parts. These will be heavy MDF doors on which we will mount another layer of 3/4" MDF with green glue. We will also have multiple layers of rubber seals all around. In the meantime, I will be finishing up the cosmetics with prime, paint, some interior acoustic treatments, register covers, etc.
