Behind the ribbon there was foam to damp 1 side of the ribbon's figure 8 response. The foam was in pretty bad shape when I got it so I cleaned it out.  I tried some different felts that I have used for damping speaker boxes  but got a really peaky response from the mic. So far best response from the mic has been no felt inside the chamber and only 1 thin layer covering the openings on the side. Attached are pictures with no damping. Any suggestions?
