1st step is to get an Ohmmeter , set the dial to Ohms ... tweeters are 8 Ohms / mids are 16 Ohms , take a reading directly from the positive /negative terminals of the K-77 tweeters and K-55M mids drivers ......post the results on the forum , this will tell us whether the diaphragms are in good working order or if they will require a replacement . 2nd step , take pictures of the crossover 's monster style clear plastic jacket wiring , since these wires were known to corrode and cause poor connectivity issues , post the pictures on the forum

there are no copper style recone kits on the market

the speakers are Klipsch Lascala Industrial Ser# 2117 rough guess is 1980 . ▶️ as-is 1200$ if the drivers are in good working order .
