JEM Performance Capacitor kits

Recommended Posts

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.

Jim from JEM Performance Audio.  Seems like I need to offer some information about what I do and why I do it with regards to Klipsch Heritage speakers.

 

The capacitors I sell are approved by Klipsch engineering.  I met personally with Roy Delgado over a year ago and discussed Klipsch crossovers in depth.  Roy took the time to explain the differences in capacitor design and how they react in a network.  My desire was to keep the vintage Klipsch models operating as PWK designed them to sound.  This all came about because I had changed the caps in my Klipschorns to the most recommended and advertised capacitors in Klipsch land.  My Klipschorns were not the same after I changed the caps for sure - but not in a good way.  What changed?  First the bass was peaked out, the tweeter was way too bright and the midrange had no life to it.  It no longer sounded like a Klipschorn should; the realism was gone.  I brought this to Roy's attention and he immediately smiled and proceeded to explain what was happening.  You have to use the correct type of capacitor to maintain the specs of the network as designed by Klipsch.  I know there are those out there that will disagree about this but I can tell you that once I installed the caps Roy recommended, the Klipschorns became totally balanced, the bass was smooth and the midrange open and detailed.  I knew others would appreciate having their Klipsch speakers performing as they should, and together Roy and I put together the authorized network repair center.  I only repair Klipsch speakers to factory specifications using authorized factory approved parts.  Your speakers remain a genuine Klipsch product and will perform just as PWK intended.  No modifications, no BULLS**T. 

 

So you are probably wondering why should I believe this guy and how does he know what a Klipsch speaker should sound like?

 

Some background -

 

I have used Klipsch speakers since the 1970s professionally and personally.  I experienced the Klipsch industrial series products in live sound reinforcement.  I used Klipsch speakers exclusively in both of my professional recording studios.  I personally own Klipschorns, LaScalas, Cornwalls, Heresy Is, IIs, and industrial Heresy stage monitors.

 

So you see I do know what a Klipsch speaker should sound like.  We have Roy to thank for getting the correct parts available to keep our vintage pieces of audio history alive and well. 

 

I don't have much time to respond to questions via this forum but I can be reached during normal business hours at theaudioroom@verizon.net or by phone - 412-401-6915.

@Chief bonehead personally met with them and approved them.

 

I heard they are very approachable, easy to talk to.

Thank you dwilawyer and JEM performance for posting, excellent info. I really want to keep the Belle’s close to stock. I have used the Sonic caps in one pair of my Heresy’s but it did brighten them up a bit too much. I will give the JEM kits a try.

What brand and type of capacitor is being used in your kits?  For example in your AA build?  Thanks

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

Jim was absolutely great to work with. I spoke with him on the phone and he was super helpful answering my questions. Jim told me he would rather ship out the parts instead of having me ship him my AA networks in fear they might get damaged or lost during shipping. I found a friend that had experience in soldering so it was a pretty straight forward job. Hopefully the video helps.

From what was said, original sound. Delgado, do not care to argue with about it.

Implications for me is not bashing others and do not read into it more than what is said so far.

Quote from JEM Performance above...is this basically taking a shot at the offerings from Crites or ALK.  If Roy is giving his endorsement of JEM and they are doing it differently than the other guys can are we to believe any product other than theirs is subpar?

It’s pretty simple and it’s not very complicated.  It’s just not “Roy” endorsing JEM, it Klipsch.  And for the umpteen time, crites and alk or anyone else and the products they sell, are not Klipsch approved. 
 

Most people who modify a part on their network have no idea how it might affect the overall voltage transfer, which affects the spectral balance of the speaker. But it’s your speaker....do what you want. If you want the original intent, then replace with original specified parts.
