In my country we import felt for jacket, i have used felt in my homemade,tannoy westminester royal,with the tannoy 15"gold monitor,for the stuffing material inside the compression chamber. The purpose of the material is to eliminate/attenuate any frequency over 200/300Hz before they go into the horn pipe. check out the tannoy westminester files, i have posted in the tannoy yahoo group. regard Green.
