I have the Tsi 100, and my tweeter quit working.

I pulled out the tweeter and connected directly to speaker wires, and it worked great. What else can I do?

Probably a wire issue or crossover issue. Take a look. Check connections inside. You could also swap around tweeters & see if it works on other cabinet & then youll know for sure if it's a wire issue or a crossover issue. Report back & someone will chime in.... welcome to the forum

Sounds like a bad cap in the crossover or a cold soldier joint on the crossover board.

Good luck

It could also be a fried resistor, $5 and back in the game.
