In my home studio I found that room treatment was the best upgrade I ever bought. I’m in the process of increasing the number of panels from 13 to 22, and this video shows the construction of one panel. I use a cheap, quick, simple technique, wrapping the compressed fiberglass in burlap without a frame or mounting hardware. OC703 is rigid enough to be self-supporting, and I can fit two panels snugly between the floor and my 8 foot ceiling. Please visit the Home Brewed Music blog at www.homebrewedmusic.com for more information on building broadband absorber panels like this. You can find a bill of materials and more details on the construction. There are also posts showing the layout of the panels in the room and frequency response measurements for different configurations.
