Sorry to hear of this terrible experience. Re the ProAc's, I would suggest calling Bill LeGall, website http://www.millersound.net. (Don't have your computer speakers turned up too loud when you go there!). He is one of the very best in the business at speaker repair, and he is exceptionally knowledgeable about a great many specific models. He is also a pleasure to speak with and deal with.
Hope that helps.
