these are 1979 Lascala , the items that will require a refresh are the capacitors of the crossovers .
-take some time to test the drivers , tweeters are 8 Ohms , the mids K-55V are 16 Ohms , the woofers are 4 Ohms
-assuming the drivers are in good working order , you should clean the voice coil gap of the HF drivers as a minimum
-the value of the speakers is about 1500$ if all drivers are operational , the rarer parts are the klipsch copper badges , so make sure not to lose them or damage them during transit .
