Tip seven: Getting Serious "If this is a man cave or a woman cave, there are further things you can do," Bush says. "One is to buy already fabricated fiberglass absorber panels in the cloth color of your choice. I would stick with four-inch-thick or thicker panels as the thin ones, like thin foam, just absorb highs and leave you with an overly mid-rangy room. If you are a craftsperson, you can make these types of panels by ordering Owens Corning #703 in four-inch thickness or in a two-inch and glue two layers together to get four inches. I use 3M spray 77 glue but others might work as well. This will need covering so I recommend a thin layer of polyester batting and your choice of upholstery fabric to cover. This can be inserted into frames or glued to a backer board to hang. Specially made diffusors work well, but tend to be very spendy. Let your budget be a guide here and remember that plain old bushy plants work well and spruce up a cave well." "I would tend to stay away from the acoustic foams available unless they are at least four inces thick," Bush says. "Thicker is better. A thin layer of acoustic foam used as a cosmetic treatment over a four-inch-thick Owens Corning #703 fiberglass panel is a nice finish and works very well. Spend some time listening and let your ears be your guide." Search “professor-acorn-pillow.html” from How to Optimize Acoustics at Home
