Help, Frustrated with Horn output


To you many experts out there. I have a two way speaker, horn and sub ( altec model 19).

Horn goes intermittently out for extended periods of time.

i changed the diaphragm, no luck. Changed the crossover, worked for awhile then no output after a couple of days. I did use a new preamp/amp at first figuring issue must have started there so I eliminated the previous gear out of the equation.

Would really appreciate some suggestions about this issue I’ve been pulling my hair out for months on. Been a lurker for years on the site and know theres a lot smarter people out there than me.

Thanks in advance

Great input, been trying recommendations.

So far still having same issue however I removed driver from the horn then opened it to get to diaphragm. Tested with ohm meter at 6.9, in the process noticed a suspicious factory connection to the female spade terminal.

Crimped over the insulation of wire! Did a continuity test got shaky when I twisted wire. Going out now to buy replacement wire, spade and o ring to replace the wire and terminals. Will update after i install. Keeping my fingers crossed.

Update-Just replaced the negative wire leading from the the terminal to the diaphragm and pow it works (for now) only time will tell.
