I have a concrete room that measures 16’-8” long by 14’-6” wide by 11’ tall that I am using as a practice space/tracking room here in Nashville TN USA. I took some advice given to me on a previous post I put on this forum about this room and covered half the wall surface with 2” thick rock wool in a checker board pattern that opposed itself on parallel walls. The carpet that I was using to treat the room before, I rolled up and stuck into two of the corners to act as bass traps(my theory, not sure if it works at all but I had it so what the hell). In all honesty, this worked very well to quiet the room down and make it adequate for playing loud but now when I track drums in the room, it's pretty much just dead sounding. It works but I would like to try and make it sound better. My thought is to replace some of the absorbers with diffusers. I am hoping to get some advice from this forum on whether or not you guys think this will work. I plan on using a design I found that uses 3” wide strips set at different depths from 1/2” to 2-1/2” deep to create a 42” wide by 4’ tall panel that I could be built out of 1/2” MDF. I was thinking of placing a few of these on the wall behind the drums and another wall that is perpendicular to that wall. Below are some pictures of the room. I have a 2x4 frame suspended from the ceiling about 2’ that I screwed the ceiling absorbers to. From what I’ve read, I should probably fill that completely with absorbers instead of using the checker board pattern that I am now.
