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

Oh and Mr Rocket science. How big would a helmholtz resonator have to be to resonate at 20 Hz? Anyone care to guess?

Size isn’t everything. I just got through explaining it. Hel-loo!

zardozmike,

     Simple, just buy and install the AK Swarm and forget about bass traps, room correction software/hardware, Helmholtz resonators, mijostyn and Mr. Rocket Science forever.

Or just buy more subs. I don’t see anything magical about the AK Swarm. What I gathered is that 4 subs, semi-carefully placed will essentially do a better job of EQ-ing itself than room correction software.
