Weird, I would try to swap it out if you are still covered under warranty

probably can have the part replaced at a workshop too
I bought it under a false name back then (and paid in cash of course and took advantage of the fact that everyone was wearing masks :D). Wouldn’t really like to get in touch with the store where I bought it. I would look for small repair shop or something like that, but the speaker works now :)
Understandable
