I have the speakers S125i of logitech, but there is a piece that is loose inside of the speakers, at the begining the speakers sounds well, but then the left speaker stoped working. I think I'm able to repair it beacuse I'm studing electronics, but i don't know how to open the speakers. When I try to open them, I think I'm gonna breake them. I just need to help to know how open the speakers, and some aditional information of how to repair them would be better. Thanks!.
