I believe they have kits for all Heritage.

The replacements are not PIO of course.

Well, just learned of the service so, was under the radar, at least for me.

I bought a pair AK2 1986 model Klipschorn back in June of this year. The original owner had bought and installed the Crites AK2 replacement as the original AK2 had incredible oxidation inside the factory installed "monster cables". After several weeks I was not happy with the sound of the Crites network. I thought it was a bit bright and harsh for my taste.

I found JEM audio on the web and contacted Jim. He sold me on updating the caps for the original AK2s. I had them installed and am now happier with the sound. I don't think they sound as good as a previous pair of AA 1976 Klipschorn that I once owned. Is that because of older ears or is it inflated musical memories? Well I guess it could be either or both.

I would recommend Jim and the caps that JEM sell. Whether the caps are approved by someone other than myself make no difference to me. I like them so what else matters?

wondering if anyone has used the Klipsch Authorized repair company JEM performance and what Capacitors they use in their recap kits? I was leaning with the Crites Sonic caps but am curious what JEM is using. thanks for any input.

After speaking at length to Jim Moorhouse I feel pretty comfortable with having JEM update my crossovers. The caps they use were actually selected and authorized by engineers at Klipsch and the only ones that will keep your Heritage speakers authentic. It's hard to argue with that.

Not real clear on whether kits sold or installed for you.

I'm pretty sure Jim will sell you the parts or you can send them in and he will upgrade them.

FYI I was quoted $40 plus $9 shipping for a Heresy Type E rebuild kit. 

that a damn good price - 10$ per  Capacitor x4 plus shipping --

I'm actually a little nervous to touch them because they are sounding so beautiful to me. All original AA crossovers from '79 that hadn't be played in almost 10 yrs when I bought them. They didn't sound good at first. Yesterday I turned the system on and couldn't stop listening all day. Can 41 yr. old caps still be good?

Apparently good enough. Have had Klipsch like a LaScala pair with old original AL crossover.

Sounded good to me. Think were 84s.

Was wondering if you got the sound sorted out. Good deal then and cool.

I am going to send them in early next week. I will let you know my before and after impressions in 2 -3 weeks.

that's why , I keep 2 sets of crossovers   my original set remain untouched , and my spare set of Crossovers will be updated  ,  this will allow me to  hear the difference

Exactly what I’m doing.

That's a great idea. Now to find a pair of AA crossovers. I see none on Ebay.

So, I'm very intrigued to try these.  Currently my 1980 Heresy mains have the networks that were in my 1981s and have Sonicaps.  The 1981 that I'm using as a center has one of the stock networks from one of the 1980 Heresys. 

 

I just don't know if I should go whole hog and replace all the caps in all three, start with just the center or just leave everything alone.  The center with the 40 year old network sounds really good to me.

AA crossovers are not hard to build. No secret that Klipsch uses polyester caps in their crossovers now and there is nothing wrong with them. My experience with caps in x-overs and equipment is the different types, brands do sound somewhat different from each other. Who can argue with replacing modern Klipsch speakers with the caps the engineers at Klipsch liked as best sounding.

Will he do a single? If not and you need a trio, I would be more than happy to splitting a pair.

Wish I had done this. Great way of verifying if you truly needed updating.
