Hi, Can anyone help me determine an appropriate price range for a good, working set of Klipschorn components: a pair of K-33 woofers (round magnet), a pair of K-55M compression drivers with horns and mounting board, and a pair of K-77M tweeters with horns. No crossover or wiring. Pulled from Klipschorn Type B, serial number 106146, during an upgrade. Also, if anyone can decode the serial number I would appreciate it. Many thanks!
