@fiesta- We must have been typing at the same time, but: you beat me to the punch, per the thoughts on stage monitors (to much editing, here).
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?

I’m mulling over what I’ve learned, here and elsewhere. I had 17 of these boxes in various stages of disrepair, a handful of them worked sort of OK. So the first thing I noticed was these blown capacitors, so I posted, but I’ve had a lot of other work to do, assessing blown and not stock drivers, repairing jack plates, and cleaning compression diaphragms and painting duratex etc. i’m not sure all of them had drivers that met the stock ohm rating, that may have been a factor, although so many of them were blown I have a hard time believing that accounts for everything. My gut tells me that the bipolar capacitors, while rated at the same voltage, simply couldn’t take the same degree of abuse that the non-polar ones did. I think I’m going to biAmping a lot of them and rebuild a few of them with really nice crossover parts for when I’m doing smaller gigs and just need a simple set up. |
@jamessheyser- If you have blown woofers, Klipsch used 15", 8 Ohm, Eminence, in most of their stage monitors. Parts Express carries a wide variety. Eminence sells direct. ie: https://www.eminence.com/speakers/speaker-detail/?model=Alpha_15A and: https://www.parts-express.com/search?order=relevance:desc&keywords=15%22%20eminence The drivers you have, probably were obsoleted, some time ago. Someone like Bill, at Millersound, if given model numbers from the backs of the woofers and horns, could probably give you any pertinent info. You may discuss having them re-coned, or buying new diaphragms which would save a few bucks http://www.millersound.net/speaker-reconing-millersound.html If you're in the Central Florida area, try these guys; https://www.centralfloridaspeakerrepair.com/ Don't tell the guys at CFS I sent you. They'll inflate the prices! I was their competition, for a few years. Then again: that was forty years ago. |
