I e-mailed Ethan about this, but he'd rather me put it here so the whole world can be helped :)
I need to handle sub bass in my mix room. I'm talking about 75hz and below. There's some sierous cancellations going on down there. Whats the best way to go about trapping that kinda bass? I checked out Ethans bass traps on his site, but they seem to deal with 80hz and above. I know it's my room because I stuck a sub in here and it did nothing practically. It was a 12" JBL sub.
Here's a thread with some info about what I've done so far...

Thanks for your help. BTW, I'm on a shoestring budget....I'd hire an acoustican if I could.
