This is an old topic, and perhaps old threads will tell me everything there is to know.
But just in case someone has new information, here goes: I recently acquired an old set of S45-2 speakers and they sound fine, but a previous owner replaced the woofers and they don't match each other or the frame clips that hold them in place. I believe the original peerless drivers are hard or impossible to find. Is that true? Has anyone found an acceptable replacement? Am I on a futile quest and should just learn to live with my modified set of speakers?
