Generally speaking: a cap will be used to roll off a woofer at a steeper rate (ie: 12dB/oct), going to ground, between a series connected inductor and the woofer. I’d say you’re clipping your monitor amps, but- that usually will take out the tweeters first. Try doubling (at least) the rated voltage of the caps, keeping capacitance the same as the original. If you can afford them (high voltage/high capacitance can get salty): try metal film caps, rather than electrolytics. Whatever you do; be certain the caps are non-polarized. Higher capacitance values can be reached, by paralleling caps, which may be a less expensive way to afford metal films (ie: Metalized Mylars). Paralleling caps DOES NOT increase the power handling (voltage rating).
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?
