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?

@cakyol,
I totally agree film cap is the better choice on speaker crossover, what confused me is if using two same-value aluminum electrolytic capacitors connected in series back-to-back, the capacitance is equal to either of the original pair or half?

@imhififan -   Half the capacitance.       https://electronics.stackexchange.com/questions/69715/can-two-electrolytic-capacitors-be-made-into-a...

I concur with rodman, half, I was mistaken about the same value in my previous post. Sorry for the confusion...

Thank you for the link.

@fiesta75
No apology necessary, your earlier post lead me to these two document from cornell-dubilier and caused the confusion:

NON-POLAR
If two, same-value, aluminum electrolytic capacitors are connected in series, back-to-back with the positive terminals or the negative terminals connected, the resulting single capacitor is a non-polar capacitor equal in capacitance to either of the original pair.

NON-POLAR
If two, same-value, aluminum electrolytic capacitors are connected in series, back-to-back with the positive terminals or the negative terminals connected, the resulting single capacitor is a non-polar capacitor with half the capacitance to either of the original pair.
Thanks for the clarification.
