Replacement capacitors exploding

Many of us who frequent the Klipsch forum and work mostly on Klipsch often go to Parts Express for caps. Lots of non polar electrolytics out there but in general I replace them with poly caps even though they are much larger and may require two to get the right value.
What exactly did you replace the OEM caps with? Brand, type, UF+tolerance and voltage.
  I have rebuilt hundreds of Klipsch crossovers and never had your problem so I am also wondering how hard you are pushing them. I  bought a pair of KP-262's once that had melted the rectangular blue mylar caps but it took really serious abuse to get there. They still played but did not sound very good.

" With all the non-polar caps out there I have no idea why anyone would do this. Now there is value in using two caps in parallel to get to the same value as one and that is the ESR will be reduced and low ESR is a good thing.

@mahlman-  "With all the non-polar caps out there I have no idea why anyone would do this."     Same here (makes no sense)!                                                                                                                I’ve never used an electrolytic in a crossover, even when repairing a customer’s.    NOR: would recommend using anything but, at minimum, metalized mylars.    Preferably: one of the better metal films.                                                                                        "Now there is value in using two caps in parallel to get to the same value as one and that is the ESR will be reduced and low ESR is a good thing."    Absolutely/all day long!                                                                                                                                                                             That post was simply an answer to a posed question.

@jamesheyser - Are you still there? Any more info on brand, voltage or capacitance? 

Bryston Amps and electronics as well as Axiom Audio both use Clarity Caps as does Whest Audio in London.  These three very high end producers of sound equipment using these caps says a lot to me and I'd be looking at Clarity Capacitors out of England for really top notch quality and high tolerance components.   They are hand made and tested, very stable and worth the extra cost.... as in expensive!
