About 15 years ago there was a company called Eighth Nerve that I believe duplicated the Room Tunes concept. The front of the panels were a hard surface and the back the absorption fiber glass. They were well built, not very wide, maybe 8" and about 48" tall if I recall. They were mounted at the room seams such as corners and where walls met the ceiling. Their triangles went in the upper corners. I found them to be effective, especially the triangles. I sold them off eventually and these last 4 years got rid of all room treatments in favor of a multi sub bi-amped system.

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
