What do you guys think of this?

I used that stuff to fill my walls. It has a density of about 1.5pcf but works well and has great NRC numbers. It's also easy to work with.

I believe it's about .62 cents a sq/ft.

Has anyone stuffed it into frames, covered it in burlap/muslin and placed in in corners as a bass trap?

Thanks!
