Did you remove the tweeter and look at the back to get some information? The name brand should be on the back of it. If it is a well known brand, Madisound may sell it or have a replacement for it.
Replacement for Edifier s350db Titanium Tweeter?
The titanium tweeter of my right speaker has become dented and I am looking for potential solutions to either fix or replace it. I have tried the manufacturer and they do not sell replacement tweeters for my model. Likewise, I have tried finding a replacement elsewhere with little luck.
