@bruce11 First and foremost, sorry for your loss!
In response to your question, when you say, "Someone blew up my deceased husband's system", do you mean the tweeters were blown out? The information you provided is the model number for the tweeter used in the Paradigm Monitor 9; probably the model 2 version. Did you have BOTH speakers tested by a qualified professional? If so, that person ought to be able to repair the speakers with the proper parts at a reasonable price. I owned a pair of Paradigm Monitor 9 originals (i.e. first version) for over a decade. With proper amplification, those are fantastic speakers! In order to replicate or get that quality of sound, these days, you'll have to spend somewhere around $2,500 and up, new. I would recommend contacting Paradigm and asking for an approved repair person(s).
Good luck!
