Good repair Suranga, but I think you should look for what caused the damage of both speakers.

In my opinion, the root cause for this failure is yet to be ascertained. If I were you, I would have checked all the components in and around audio IC, to obviate the chance of any leaky components. The set is likely to have different audio modes, controlled through uController. That should also be checked! Some questions to customer like how this happened, when and what did they do immediately prior to it etc. can provide some clue. In all probability, the set might come back or go to someone else soon!

Both open might be rare, unless perhaps one burnt out and the owner just kept using it on the other.

Thank you for the article. I understand that you didn't need to take any next step in reparing this device Suranga. Which you wrote about in your conclusion, and that both speakers still kept working. I believe this blowing up speakers thing is a common problem when for instance in class A amplifiers the DC current burns through the loudspeaker coils. High generated temperatures easily can turn the coils in distroying hot heating elements.
