RM3000 satellites

mapb

I purchased new in 1994 an RM3000 package. While under warranty, both satellites were repaired and each were repaired after warranty expiration. Both have been in storage for about six years in my garage. Irregardless of the repairs, I have always liked the way they sound. They were just brought out of hibernation and initially, sounded fine, but after a few minutes, the midrange was lost. I pulled the grills and pieces of the foam surrounds fell out onto the floor. Does Polk Audio offer replacement parts for the series 2 rm3000 satellites? Is there a newer surround material or cone? If replacement of the mid ranges or foam surrounds involves plug and play or simple soldering, I think I am capable. I do not know all of the proper terminilogy, but hopefully this is enough information to get started.
