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?

To replace any cap, know more about the cap you are replacing... the methods of both manufacturing and usage have changed. Also, many new types are available now.
As I don't have the time or space to discuss the above limitations, I will give some advice instead. First, ALWAYS buy your caps from a REPUTABLE DEALER, not the local parts store. Second, ALWAYS use replacements with a higher voltage rating to prevent problems. For example, if a filter cap is rated at 450 volts DC, use a 630 volt cap. If you don't know beans about caps, DON'T TOUCH YOUR PRODUCT and find an expert. The types of cap DO make a difference!

Only true about higher voltage in some applications, like this one. Not true for DC supply voltage filtering!

Get the Mundorf EVO silver/gold or SESGO which are 2x's the price, but worth it. 
Built to last forever. Sonically, 2nd to none. But as i say, they are pricey.

As the saying goes, " If it ain’t broke, Don’t fix it".....for example, my cassette deck is on its 38th year, never been touched, except a belt change. It plays like day one...
