Query: control center breaks after two years

If you don't mind having to replace the speakers after 2 years they're good speakers. The control box breaks and it can't be replaced. Even tech support said it's a very common problem. The only thing you can do is buy another set set of speakers. They will offer you 50% off. How nice of them seeing as it's a common problem that can't be fixed after only two years of very little use.
