Acoustic treatment

I want to build my own bass traps and was wondering if there are any other alternatives to fiberglass and rokwool. Foam is not a consideration as I don't believe it has the necessary qualities for absorption. I have heard of cotton batting, does anyone have experience with this material. The idea of fiberglass makes me itch just thinking about it, but I'm resigned to using it or rokwool if that's all I have.  Please make suggestions and let me know your experiences.

Thanks
Mike

Many older theaters were designed with a combination of bass traps,diffusers,resonators,and pillars(aka tube traps) incorporated into the structure. They have incredible acoustics.The DBA system and room treatments can work well together.

It looks to me like an expensive alternative to the DBA system

I agree with you Tim.The DBA system has my vote.

I'd never heard of an ABT before.I did a little more reading and understand better how it works.It's simple to implement,but expensive and probably a royal pain if it ever required servicing.
