Pretty solid weekend of work. Only 2 trips to Home Depot this weekend so that was an improvement. By the way I am convinced that I could build a home theater INSIDE of a Home Depot in 2 weeks.
I did have a nasty fall off of the ladder into the wood scrap pile. Very lucky that no major damage was done.
I got all of the low voltage done. Boy am I happy to be done with that.

Next up was building the joist muffler for the HVAC return. Its a tight space in the back. My original plan was for a decoupled dead vent but the slope of the roof and the dimensions of the (2) 7" supply and (1) 10" returns made that not possible.
So after a discussion with Ted White I decided to go with a joist muffler.
As a side note: Ted has been great to work with and even called me back on a Saturday to get me lined up. TWO THUMBS UP!!
Here is the space that I have to work with:
I have started the construction of the joist cavity for the 10" return. The return will enter the cavity on the left and go 10 feet to the right towards the smurf tube that you see above. The side are the (3) 2x12 and (2) 2x12 seen above. The top and bottom will be 3/4" PW. The inside will be GG + 5/8" DW + GG + 5/8" DW. Insulation will be on all interior sides.
The 9" supply will come in on the left side as well and split into (2) 7" ducts that will go to the left and right over the joist cavity and each will follow the slope of the roof down into the soffits that are inside the sound proof shell.
I need to extend the sides down 3-4" and make the hole for the return. Seal it up with acoustic caulk and then on to GG+DW of the interior.
As always I am open to any suggestions.
