Electro Voice Horn Tweeter Repair T35 Klipsch K 77 EVST350

An older video, where I repair a horn tweeter from a stadium loudspeaker system. This is the Electro Voice T-35 horn, and I replace the diaphragm, and test the repair. These horns are easily.
In this video, we replace the diaphragm on the Klipsch K77M. The Electro Voice T35 and ST350 are similar. Use diaphragm part # 89486A to restore the original performance of this horn.
This is blown radiotehnika tweeter.

I just got a set of Electro Voice Wolverines and I’m very pleased with how good they sound

Hi Francesco
Great video, thank you. Massive help!
Just sent for the diaphragm to repair my T35, but I was wondering if you could tell me how to determine the positive from the negative on these phenolic ones, please? I ask because I cannot see an markings on the ones I've ordered.
Many thanks for your help,
Tel.
