Hi everyone. I was given these CP-1 speakers many years ago, without knowing anything about them. They’ve been stored since then, but I recently decided I wanted to try to restore them. I pulled off the grills today and discovered that someone prior to me pulled the woofer (k-44e) in one speaker. I REALLY want to restore these, but I can’t find any info on the woofer that originally came with these, or anything that could potentially serve as a replacement. Any suggestions from someone with a little more info on these? Thanks!
