Replacement capacitors exploding
I replaced the capacitors in the crossovers in my Klipsch KSM-1 stage monitors.
There is a capacitor that runs parallel to the woofer which had blown in a couple of my dozen stage monitors. They are from the 90s, which is not ancient, but I figured maybe that age is a factor so I swapped them all out.
The replacement capacitors have all of the same numbers printed on them but are a fraction of the physical size, and in just one season almost all of them have blown. I don’t think they were being pushed harder.
Is there a way for me to order capacitors with the same specs printed on them that are also heavier duty in some other way?

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. |

@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.
