Greetings: This is my first post to the forum, although I've had my horns since 1998, this is the first problem I've ever had. Here is my situation: I have one horn that has lost all the low and seemingly some of the midrange. Stock 1993 with factory AK-3 crossover. The mid horn and tweeter horn are producing sound, but all upper range frequency. Here's what I've done: Checked the fuses, swapped the fuses, no change Checked all wiring, cabinet and speaker to amp, no visible issues They are powered by monoblock amps, swapped those, no change, both amps work other horn fine Pulled the side panel out to see if there was any visible issue inside the bass cabinet (like mouse nest) looks brand new inside Put meter on both set of lugs. upper and lower, zero continuity on either set of lugs, but the upper horns are at least somewhat working. tried the same on the good speaker and both of my Cornwalls I have set up beside them. All three of the other speakers, including both set of lugs on the good horn, all all showing 4.2-4.5 ohms of resistance. Put meter directly on the woofer, zero continuity. I'm not sure how the horns should sound with the bottom end completely non functional. But there must be something wrong with the upper crossover/horns as well, otherwise they should show that 4ohm resistance the good one shows? Any help you folks could provide would be appreciated.
