@fiesta- I’ve bought from Mouser in the past, as well. Believe I got the eight last EPCOS filter caps, I installed in my Carys, from them.
Do they carry any higher-end films?
Just got back from work and (at times) searching their site wears me out.
I miss the big-ass catalogs, all those guys used to send out. Just old-school, I guess!

@czarivey - "Why it was necessary to replace??
if you connected them backwards, they will explode"
There is no, "backwards" with non/bi-polarized capacitors!! 🙄

@jamessheyser- Again: try contacted Millersound, with the driver numbers. He should be able to fill in the blanks (ie: even whether stock, or not), for you. Another avenue, far as possible OEM driver info: https://www.klipsch.com/support-nav

@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. |
@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). |
ClarityCap makes excellent capacitors.
Matter of fact: I have four ESA25, 250V and two ESA 50, 250V caps looking for a home. Also: two Mundorf, CFC14 (14Ga), .46 Ohm, 2.7 mH, air core inductors, looking for a good home (someone that actually intends to use them), for the cost of UPS shipping, if anyone is interested.
I was experimenting with a pair of Maggie MG12 crossovers and ended up going with some Emerald Physics speakers, some years back.
ANYWAY: The OP’s systems are stage monitors. Whether vocalists or musicians: hearing themselves, on a stage, with everything else that’s playing around them, is always a challenge and ultra high fidelity, imaging, etc: never much of an issue.
Not that I mean to put words in the OP’s mouth. Just sayin’.
The caps he needs: used from inductor output to ground, in a 12 dB/oct network. Absolutely no need for such high-Dollar caps as Clarity’s.
We’d been in contact, via PM, a few times and he’s disappeared, of late. Perhaps: having found his caps?

@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.

If one took the time to view these pics of Klipsch stage monitor crossovers, they’d note that the OEM/factory caps, comprising the LF circuits, are bipolar electrolytics. ( https://www.ebay.com/itm/Klipsch-Type-KSM-2-Crossover-/392714043491) ( https://picclick.com/3-Three-JBL-S3HC-Klipsch-KSM-15-and-Klipsch-231960707452.html#&gid=1&pi...) ( https://picclick.com/3-Three-JBL-S3HC-Klipsch-KSM-15-and-Klipsch-231960707452.html#&gid=1&pi...) This last link contains a crappy pic of the KSM-1 crossover. The silver can at the bottom, should the stock electrolytic, in the LF section, that gave the OP his initial problems. Scroll right and it's third from the last pic: ( https://reverb.com/item/13889916-klipsch-ksm-1-vintage-15-2-way-floor-monotors-with-phenolic-diaphra...) If Klipsch provided him with new, replacement crossovers, they’d probably still come with electrolytics, in that position. I've hated electrolytics, in crossovers, from day one of my experience with electronics.
The electrolytes will dry out and the cap will lose it's values. Over-voltage will cause the electrolytes to expand and explode the cans. BUT: they've been used, for the sake of economics and availability, by speaker system manufacturers, since the beginnings of audio. |

@itsjustme- It's comical that you'd say something like, ".... are you familiar with all the rating components, and with all the various types of capacitors and their pluses and minuses? It gets pretty arcane quickly." and then assert, " Electrolytic, which would be smaller, are polarized and cannot work that environment. They would be reverse polarized (sometimes) and almost certainly fail." fyi: Bipolar electrolytics have been used in countless speaker systems, from the very beginnings of audio. When I was in the electronic repair/speaker reconing business, I lost count of the systems that came through the door, with just one bipolar electrolytic, meant to block lows from the tweeter. Perhaps another, higher uF value, if there was a midrange driver. Junk, but still........

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).
