Bryan states there are many DIY sources for treating your room. The specs I followed are laid out by Anthony Grimani and then I tailored them for my room with the help of Wilfried Van Baelen. The specs for Anthony’s DIY acoustic treatment recipe is laid out in the diagram below. Bass traps in the corners and then combo panels on the front wall. The side walls alternate with diffusors and absorbers but do NOT mirror each other. You’ll notice if you have a diffusor on the left wall there will be an absorber on the opposite wall. 2D diffusors in the front of the room, 3D diffusors in back. Anthony recommends absorbers in the front half of the ceiling and 3D diffusors on the ceiling in back. Wilfried felt you should include bass traps on the ceiling. I found the Auralex Geofusors a perfect workaround. It is a 3D diffusor that can be back filled with absorption and double as a bass trap. I placed the Geofusors above the MLP. I hung an acoustic cloud of the Auralex Sustain Lens diffusors where you see the 3D ceiling diffusors in the diagram below. The cloud hangs perfectly beneath my PJ. Here is a diagram of Anthony’s specs for room treatment that I used for my room. IMO these are the specs that matter because unless you get them right the specs of your gear don’t matter, just like the title of this thread:
