I'm pretty excited about my new room i'm building


I am fortunate enough to be getting kicked out of my dedicated audio space 12’x16’x9’ to make space for the kids to have separate rooms .I am remodeling a stand alone building on my property.The dimensions are 16’x24’x9’ with 10"thick cement floor.I am open to either treating and painting the floor or a floating pergo style floor ( no carpet ) with floor rugs .the walls are drywalled 2x6 construction insulated with redwood board and batten exterior, above the ceiling is insulation with open attic area(which I could add more insulation). As a few of you know I am fully off grid and generate my own power thru solar and gen backup into large battery banks then inverted to my house etc.The only furniture per say will be three reclining chairs etc .I will transfer a lot of my treatment panels and add more as needed. Also I will be trying to set up a humidity and temp control for this room when not in it, I was thinking 60deg 60% humidity .thoughts?
Any tips or thoughts are appreciated .
Thank Ray

I still will have my home theatre setup which is pretty nice in the house also so i’m stoked .

Foam will only be better if it is denser, but foam if typically not ideal as it created a stronger mechanical connection which is what you don't want.
As far as insulation, have you priced foam, where it is sprayed into the walls? Acoustically I would think that would be better than fiberglass.
Foam won't deaden/damp the Gyprock (drywall) panels like compressed 2 x 4" batts will, as the cavity is 4" you have 8" of batt compressed into 4" that will damp/deaden both side of the dry wall.

He used 2x6, so if you use typical 4" fiberglass bats, its not going to fill the void. If he used a r36 insolation for 2x6 framing, that would be a much better application. I know of applications where the foam (which hardens) would fill any voids with the fiberglass insolation. I would think the denser the internal wall the better the acoustics? I live in a log home 6" thick and the solidity of the wood makes for very good acoustics.
Yes, solid is your friend. You don't want the bass frequencies to flex the drywall with each compression, and then relax with each rarefaction. There is a reason no-one but homebuilders make speakers out of drywall.
You want spring and push, not static foam just sitting in there, and if you have too much spring behind it, it will over time budge and release off the studs and noggins.
