PM me for acoustic treatment pdf book if you'd like.

Thanks for the offer. I like reviewing anything I can get.

I've done superchuncks bass traps in the four corners of the room, absorption on the back wall (huge improvement there!), absorption at the reflection points on the ceiling, and diffusion at the side wall reflection points. All of this reduced the RT60 at all frequencies to below 0.4. The problem I have is that the room is built to be relatively sound proof which means the bass energy is reflected back into the room. I have a pair of subwoofers that I am using to cancel some of the peaks in the bass region. It's always a work in progress but it's fun.

Regards,
Bill
