I am in the process of adding a basement with a dedicated theater room. right now during the construction phase my metal register boxes for the upstairs HVAC are exposed. Sound is passed through these metal registers very easily. I am planning on using whisper clips, 2 layers of 5/8" drywall and green glue on the ceiling. Will this take care of all the sound or should I wrap the metal register boxes with MLV or any other product before I drywall the ceiling? I am ripping everything out and having a new HVAC system and new register boxes installed in the next couple of weeks so now is the time to do it if there is a benefit. Any help is appreciated!!!!

Thanks,

This is my first post to a forum EVER!!!!

I've thrown some dynamat supreme on the boots in the past and I liked the result. I've also lined some with Linacoustic. if they are connected with round pipe substiting flex duct for the last few feet can often provide a benefit, And of course surrounding the ducts with insulation.

If you are into replacing the boots My home depot usually has some rectangular floor registers that are already lined with linacoustic. They call them insulated.
