Okay, fair enough. And Mea Culpa. I'll try to tone it down.

Yes, I've been helping people to build their own acoustic treatment for years. Shortly after I started my company, I wrote my
Acoustics FAQ to explain all I knew at the time about acoustics in a single source and with no commercial references. I still maintain that page, and I still answer questions about DIY treatment all the time in many audio newsgroups and web forums, including my own at Musicplayer.com. I feel so strongly about the importance of acoustics and bass traps that I'm glad to help people build their own rather than go without.
