If they sound dull and recessed, caps may help. Use a good film and foil cap. I have not cared for the sound of metalized caps.
I will check on that, thank you!

Hi there!
I'm helping a friend of mine, he has a very nice pair of vintage klipschorns (I'm pretty sure they're late 1970s - early 1980s) he's thinking of replacing capacitor on his ak2 crossovers just for mids and highs. Everything still original on his speaker, capacitors, wiring, tweeters, mids, etc.
I'm well aware of the fame ak2 crossover has, at this moment he doesn't have the money to buy new crossovers.
My question is, is it worth it replace caps? Am I going to hear a noticeable improvement?
I told him he could replace the wiring and tweeters diaphragms ( it helped me on my khorns)
I want to hear you guys thoughts and make the right decision.
Thank you in advance

I don't know if I like SoniCaps or not, but I think you'll be fine with those crossovers. Enjoy¡
Thank you!

My klipschorns started looking good!
I have been doing some research on how to polish, repair light scratches and make them looks nice! Unfortunately didn't have success since they're painted. Any suggestions on what I could use to blend light scratches and keep them nice and shiny? I used bees wax but it doesn't last. Any suggestions I will appreciate!
Thanks in advance.

lol. I spent $5K to bring back the T2A, T4A, the graded 5mH ferrite bobbin, the 2.5mH, 4.0mH, and all the small air cores - all in wax. How REAL do you want it?Considering how long it takes to wire and solder the things, $650.00 a pair shipped is a good deal. Labor is $150.00 per board. The rest is parts.
Beautiful job!

I suppose I'm too late. There is no reason to replace any wiring. It never goes bad and is too short to impact the sound.
There is no reason to "rebuild" working drivers; leave them alone. The -Ms are good drivers. The diaphragm for K-55-Ms have not been available for years, though one vendor says he can adapt a K-55-V diaphragm.
The original tweeter was a K-77-M *if* the K-55-M is original. K-77-Ms were installed beginning in 1980, maybe late 1979. Since you have Z-brackets, the K-55-M should be OEM.
Your best choice for a crossover is an AK-3. A K-55-M easily reaches 6000 Hz, so your 4500 Hz crossover point is unnecessary. You should be interested in matching the horizontal dispersion of the squawker and tweeter at the crossover point. I expect Klipsch made an attempt at that.
I've never heard that tweeter, but a pair of K-77-Ms will return your Khorns to the original sound and performance.
Thank you for your feedback, I got the AK3 Gold from Crites, and wow! They sound way better! Compared with the A 4,500hz.

Bob Crites mentions by error that the K-77 F is a clone , while it's an OEM Original made with the original EV tooling .
The K-77M was discontinued by EV in 2000 , the EV Tooling was purchased and moved to the Philippines under new ownership ,with the final assembly delegated to a third party to cut manufacturing costs ,the K-77 production resumed in 2001 , under the new designation K-77 F which is not a clone since it's manufactured with the original EV tooling same thing for the new diaphragm cups .
That's so interesting. Thank you for sharing that information.
At this point I'm just going to wait for the right k77m for me. I spoke with Michael Crites, he told me alnico tweeters could loose magnetism if dropped or just because age. So I'm having second thoughts on buying K77.

Just found this.

nope , the specs sheets for the late 70's T-35 Alnico and T-35A Mud , show identical Frequency characteristics and Output sound pressure levels - 3.5 kHz to 15 kHz ± 3 dB / 104dB W/m

That's so interesting, what I could understand there's no difference between each one, I wonder what advantage the K77M has over k77...

You are correct, the K77M has the ceramic magnet, and it's response differs from the older alnico tweeters. You are on the right track looking for a k77M replacement, to preserve the proper voicing of your Khorns.
Thank you! I was looking in eBay, found a few pairs, k77 and k77m but I think prices are too high right now.

you can buy 2 types ,K-77 Alnico -round magnet or Ferrite square magnet
For what I read, and correct me if wrong. K77 round magnet is the older version and the K77M square magnet is the newer-ish version? My klipschorns are from 1990, not sure if I would hear any difference between the square or round K77?
Also, what's a fair price for a pair of K77M tweeters? Seen a few on eBay but I feel their prices are too high.

Hi there!
I'm looking for a pair of K77M tweeters, I'm trying to get my speakers back to original. As it right now I have CT125 tweeters, I want to compare them with the original ones.
Thank you in advance!

You would want to use the tweeter that matches the crossover that you decide to use . Back to the non stock crossover and tweeter issue, I prefer the stock tweeter , but you may prefer the ct125 with its lower crossover point , after all It’s a matter of personal preference . I would listen to them for a good long time , maybe someday you’ll find a stock set to compare with. You may very well prefer your own set. That would be awesome. Have fun 🤓
Thank you!

the klipsch mids horns for 1990 are composite K-401 , if that's what you have , then leave as is
Yeah, they're composite. I will leave as is then. Thank you!

Are you sure to need new diaphragms for your K77M tweeters? Or are you searching for K77M in the first place? If they run they should be good. The diaphragms which are in the market today are mostly cheaper and not so good sounding diaphragms from China. The old original ones of a K77M are good sounding if they are working and original.
I was searching for both, but also I was searching for my mids, I couldn't find a lot of information in regards of rebuilding my k55m.

it's not only the tweeters , it's the crossovers and the cheap wooden horns , buy a pair of K-401 mids horns , a set of K-77M , as far as the crossovers , the AK-3
Didn't know this mids came wooden.
My speakers are from 1990.

I was searching and I found new diaphragms for k77 tweeters but I couldn't find a lot in regards of k55m rebuild kit. That means there's not a rebuild kit? At least should I open to clean it or leave them alone?

I can only agree with that. The CT125 in my 1977 Lascala gave a kind of soft hi-fi sound, of course they were also too quiet, but that wasn't all. The vocal authority of female voices, the powerful dispersion of the original K77(M), the way e.g. an old CSNY recording fills the room with energy, an acoustic Martin guitar, all this is so much more authentic when using the original K77 or K77M. The directivity characteristics together with the K400 create a sound that is one piece. I'm happy to put up with a little sibilance from the old tweeter design. Incidentally, it was almost gone when I finally used the original T2A autoformers and the SPL ratio to the K400 was right.
I started searching for a pair of tweeters.

The original tweeters are excellent ,but even more important, they are also the perfect acoustic match to the other drivers . I would recommend returning them to stock.The ct125 tweeter changes the character of the Khorn 🤷and to my ears in a negative way. Unfortunately as was mentioned above, the 4500 hz crossover isn’t compatible with the K77 , but , all that can be fixed . Stock Klipschorn is the way to go , trust PWK’s designs ,be suspicious of the snake oil salesman that promises improvements to this fine speaker .Congratulations , and good luck.🤓 16 gauge is fine.
Thank you for your comment! How do I know if my klipschorns came with k77 or k77m and which crossover would be good for stock gear?

No. You have the correct tweeters for that style crossover. To sound “right” you need to replace them with Klipsch parts.
Ok! I was thinking down the road get the original tweeters and compare. Thank you!

Those aren’t Type A’s. Don’t run those with stock tweeters. That network runs a lower crossover point that will stress a K-77.
CT-125 is an Eminence APT-50
I don't have the original ones, I think I'm good for now lol

Actually, you have the Crites A-4500's to go along with your CT-125's. It would take some work to convert them to AA's. I like the CT-125's, but found the sensitivity to be too low for the Khorns. It's a great tweeter for the Cornwall or Heresy, if you make tap changes to bump up the voltage to them.
So that means, I would have to change my tweeters?
Klipschorns AK2 crossover rebuild?
