Hopefully I can reuse some that already exists. While my current bass traps were installed with adhesive, by the time I got to the absorption panels I realized I could skip the glue. I attached them using long(ish) thin nails partially in the wall at an angle. Then just slip the foam onto the exposed nails and it’s kind of like oversized velcro. So I know I can reuse those panels.
I’ll probably hold off entirely with the diffusion until after I move in equipment, furniture etc. and can hear how that changes things.
The gobos are definitely on the buy list.
It’s kind of funny that once I realized this was pretty much as expected it’s all ‘burgundy or purple?’ now.
or perhaps a pair of each?
