Yes, the wall with the water meter is the front wall that will eventually get a new TV installed on it. As had to get the electrical panel upgraded to a 200amp service, all the wires for the house didn't fit in tight to the wall around the ceiling level. Rather than having another psudo bulkhead around the electrical box that would have stuck out, I decided to make that into a small room that houses the networking drops.

In trying to keep the sound from traveling though the house, I tested a set of speakers in the room before I finished it. The sound traveled mainly down the return air ducts, so I took extra time to put in better sound insulation around those parts. That is why there is such an interesting box around the back of the room. I put on it a heavy rubberized sound mat like they use on cars directly to the outside of the square duct that took out the ring sound that travels. Then I put on a 3/4" acoustic sound tile with 2 layers of 5/8 drywall. The hope is that the mass will deaden the sound travel through so there is not enough energy to get into the duct.

The ceiling is all on resilient track and 5/8 drywall with a layer of roxaul safe'n'sound. I didn't put in any pot lights into the ceiling as that could be another hole for the sound to get into the ceiling space through. I did end up having to put in a single access hole at the front for the outside water tap shutoff. It was just too much cost to get it repositioned.

The room is that almost square 15'6" x 17' with 4 doors along the back of the room. This kind of limits where you can place speakers and any additional sound treatment along the back wall, but we will see what is needed. The small bit of wall along between the doors to the laundry and workout room could support a parametric diffuser like some that I have seen designs for on the internet. I'm a woodworker so making one with some MDF that I have laying around would not be too hard.

I've got the OSB laid down and screwed securely, so I hope to get the engineered floor installed by the weekend.
