Need ideas for low freq absorbers that look good
I'm starting to gather ideas to put some low frequency absorbers where I play bass, in the basement of my town house. I've never had complaints from the neighbors but, in order to make sure I don't bother anyone and in order to cut some rattle I hear even at lower volume (wall shaking), I'd like to ad something to some of the walls. I as to look good, though... decorative even, if possible. Any ideas what I could look into? Pics would also help...
