Hey, I'd seen this site on the net and decided I'd try and build 'EM (see links below). It took my wife and I a day to build two 6'X14" traps. I can hardly believe how much of a difference it has made in the sound of my booth... it has just sucked out the mud. I pulled the trap out a couple of times just to check it out... man, what a difference. And the best part... they cost about $50 to build, for BOTH!
I'm still looking for a great RPG type diffusor design that I can build but the F. Alton Everest Acoustics book is a bit cryptic to decipher. Anybody know of a good DIY design??
My design source:
"Everybody loves that damn monkey"
