If the tweeter's not fused (likely) then it's probably blown. Your sister probably blew it by driving it into distortion with an underpowered amp or receiver. But since you sold them to her, it's definitely your fault!
I'd contact the company and obtain a replacement tweeter. If the speakers are still under warranty and you send it to them, they may even repair it for free.
Next, you need to get your sister a more powerful amp if she wants to continue playing the speakers that loud!
Happy New Year!
