Hey all, I was wondering if anyone has done comprehensive testing on absorption using cosmetic latex sponges like these: http://www.trim.com/?q=cosmeticsponges
Out of the bag they sound (against the ears) like they absorb a lot of midrange/treble energy. I installed half of one of the rhomboid wedges in each cup (0.5" thickness) and the results are positive and subjectively better than the other materials I had tried before (cotton wool, various foams), and I'm curious as to how would these compare against the proven absorbing materials like fiberglass or mineral wool. Anyone?
yes, see nick n's "makeup pad memory foam mod" near the bottom of Post #1 of FIMM :)
