Tell us about your acoustic treatments

After three years my HT is about 95% complete, i have huge corner super chunk bass traps, i use wooden diffusers for flutter echo and 4” OC703 absorbers at the first reflection point.
my screen is an AT type, i have zippered pillowcases with pink owens corning pink fluffy to place under and all around the LCR. I also made (all diy) some skyline type diffusers for first reflections and flutter echo.
