I'm designing a studio for my backyard. It's already funded and I've been giving the contractor directions on building it. The dimensions (feet) are 18W x 25L x 9H. The ceiling is a vaulted ceiling that's lowest point will be the 9ft and will have exposed joists. The floor will be a floating floor (lower level concrete slab) with contractor vinyl on top. The drywall will be doubled with green glue and be screwed into the isolation clips/beams. I've got a pair of JBL 8' and a JBL 12' sub. I've also filled out your room analysis form so you should be seeing it soon. I'm curious to know whether or not I should separate the frame into two rooms or keep it as one bigger room. I suspect that if I separate, I'll be struggling with lower frequency issues. I've worked in both kinds of studios and have no real preference as to which one is better (separate or combined). They both have pros and cons for me. Any help is appreciated.
Thanks and hello from New Orleans.

R, I do not see any noise measurements that justify your construction methodology. Have you taken noise measurements? A double wall is only good for frequencies above 125 Hz. It will not provide any low-frequency isolation. A floating floor on concrete is a waste of money. The concrete slab will provide the isolation requirements for most applications. What are you doing for low-frequency management inside the room? You have large issues below 160 Hz. These are + 12 - + 15 over baseline and must be treated. Fill out the information in this link and include your noise measurements. https://acousticfields.com/fre.....-analysis/
