above is my unfinished room. Thick parts are concrete, and outside wall (top) is wood insulated with spray foam insulation.
I am closing off the small part on the left top side with the double doors.
Room is 37 long and 17ft wide. I want to leave the large part of the room open and I would like to build a riser for the 2nd couch.
I'm completely open for building material suggestions, as i have nothing but framing done.
I'm not at all concerned about sound isolation, but i want to reduce or eliminate echo in the room with absorption/diffuse panels.
I'm not sure what one is better, and where i should put them.
