Room Treatment

After pricing commercial products such as Sonex, I decided to make my own acoustic panels. I have four panels on the wall behind the sweet spot, and they work very well. I used convoluted grey packing foam glued to hardboard panels covered in acoustically transparent white fabric. I got the foam from work, and the perforated fabric from a local store. I can neither measure nor compare my panels' performance with products like Sonex, but for me they work fine. My only regret is that I didn't make more!

Herman,you can buy them at any Home Depot,Lowe's etc.Just remember to put bare fiberglass side out towards the room and cover them with some fabric so you don't have fiberglass particles floating in the air.Good Luck!!!

Happy New Year

I bought 24" wide insulation at Home Depot, the type covered in a translucent pick plastic with a white fiberglass fill, some 1/4" luan, and some reasonably transparent fabric that matched my room. I cut the 4'x8' luan into 2'x4' sheets, stapled the insulation to the luan at the edges, and covered with fabric. These panels are both reflective and absorbtive. I've placed them at key reflection points and behind my listening position. The result has been quite dramatic, although I am still curious what a well done commercial solution would sound like.

this is not a simple question with simple answers. absorption alone is not as pleasing as a combination of absorption, deflection and diffusion. the best sound room i've ever experienced is at goodwin's highend in waltham, mass. you can view it on thier website: goodwinshighend.com. the site also has some useful information for diy'ers (tho its not intended for this purpose). i'd suggest you take a peak. BTW, i have absolutely no connection to goodwins. i simply visted the store on a trip to boston/providence last month, was treated exceedingly graciously, and learned some important lessons from mr. goodwin and his staff.
