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 .

That will work. Big waisted space behind the chairs, you only need half that.
With that length you could do what I did though, move your listening chairs and speakers/subs back say 8ft.
And then have with a short wall (your father in law could make no problems) behind the speaker for your subs and mains.
And have something like my sunroom, maybe as a bar with small fridge behind one of the short walls, small table/chairs to do some modding/soledring or work on.etc.

I finished my purpose-built two channel room a year ago. You are at the perfect stage to optimize dimensions with shelving and storage.

1. I suggest looking up dimensions obtained by a big simulation, done properly, by the School of Acoustics at Salford University in the UK. Results and a paper in the professional literature are offered for download.

2. Stereophile had a feature article on a case study of a music room, early in 2019. Lot of good ideas there.

3.  My own experience with Quietrock 545 and elastomeric glues and caulking from Chemlink was very good. Q 545 is not cheap, but it's solid solid solid - more than an inch thick, two formulations of gypsum plus a layer of sheet steel. As for Chemlink, we used at least 10 cases of the stuff.

My results were excellent. The quality of silence in the room is remarkable - in fact, most visitors remark on it right away. When I want an intimate sound, I sit in the usual listening position. Big bass, in a corner.

Good luck!
I used that acid stain in a 24x24x17H building where I make wine. Results vary with what you want to achieve. Your going to want to seal it. I assume a moisture barrier is under the slab? Your basically etching the concrete with the acid. You can get some really cool results. I don't think you will be walking around in your bare feet. 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. 
Another good idea is to have shelving on the wall behind the speakers and the wall behind the listening position. Or if not shelving, something else irregular.
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.
