I acquired a set of KLH Model 20 speakers. They have the original boxes although a couple of the flaps are detached. One is still in white paper in the box and the other had been taken out at some point and the grill removed to inspect I guess. Everything looks good and only one small mark on that cabinet. I have not looked at the other one yet. The woofer surround is intact but the coating has dried and probably leaking air. I am guessing the crossover capacitors are dried out too. My question is I plan to sell these if possible as I am speaker poor(LOL), am I better off recoating the surrounds and doing the crossover update or leaving them as is before I sell. The boxes does have some wear and maybe a flat cardboard piece is not there but the cardboard corners are in both boxes. If the second speaker has never been unpack, I am guessing the cabinet is probably perfect but can check. Suggestion or ideas are appreciated.
