Yeah, I still may do that, just pipe it into the ventilation I am using for the fan.
Passed framing today. Took him about 30 seconds. He said I don't need to do an insulation inspection, so I am good to go until the final inspection!
Here are things which may be useful for homeowners:
For the recessed lighting, I just screwed the quietbox directly to the joist for the inspection. I explained to the inspector that I was going to use remodeling cans so that is why they are not in place yet. He didn't object. I'll decouple the boxes when it is time to install the drywall.
For mechanical, I had to install the fan for the dead vent. This is 8" ducting. This closet is going to remain unfinished so I will have plenty of room to make changes / adjustments after the room is done. With this huge 750 CFM fan running, the only sound I hear in the adjacent room is the air rushing through the grate. With the speed controller in place and proper design of the plenums, I should be able to mitigate any fan noise inside the theater. The fan will probably need to be isolated from the joists as some humming is flanking into the room above.
This end of the fan is going to connect straight into the dead vent. The soffit for the vent is going to run across the room to the other side, where I am going to put a plenum with a couple registers.
Here is how I did the fireblocking. Basically just took mineral wool and stuffed it into any gaps. The inspector didn't take a 2nd glance.
