Hi everyone, I am looking for additional information and potential buyer regarding a pair of vintage 1950s klipschorn speakers in excellent working condition. The serial#s are 1671-1672 on the cabinets and 1832 & 1681 on the horns. I'm looking for information regarding their collectibility, value and a potential buyer. I'm located in Houston so anyone local interested please msg me otherwise I can ship at buyer's expense.
