All of my 2-15 bass cabs that I have ever owned(one as old as 1966) had CTS drivers with a paper dust cap in which the center had a hole in it that was closed off with what looks like a thin layer of felt.CTS driver where around for a long time. I just picked up off ebay a 15" that was made in mid 75.
