AndreG. Posted March 2, 2021 Share Posted March 2, 2021 I´m really just a noob when it comes to speakers, so i need the knowledge of this forum once again. I have my Heresies, over 40 years old and i´ve always been wondering: What does a really bad cpacitor sound like? Distorted, bass missing or bad imaging (wall of sound)? I know, the only objective way is to take it out of the XO and measure it, but that´s just numbers. 3 Quote Link to comment Share on other sites More sharing options...

Yes, they may sound distorted, scratchy, intermittent, but most often sound like there's a blanket over the front of the speaker. Muffled, too soft. Measuring for uf value is not enough. Need to measure for ESR as well. 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted March 2, 2021 Share Posted March 2, 2021 You should get action here. Instead of measuring old caps, most just replacing, refreshing them. For closest to original sound, JEM seems to be gaining in popularity here as a newest Klipsch authorized supplier. Thanks! 2 Quote Link to comment Share on other sites More sharing options...
AndreG. Posted March 2, 2021 Author Share Posted March 2, 2021 Thanks Billybob. Truth be told, i´ve already got new Jantzen Z-Caps here that i will install. I just wanted a discription of the kind of "bad" sound one would expect to hear. 1 1 Quote Link to comment Share on other sites More sharing options...
muel Posted March 2, 2021 Share Posted March 2, 2021 While my original Heresy's still had the original caps there was nothing about the sound that I can really point out... maybe missing highs but not until I replaced the caps did I notice that is was like removing a blanket from the speakers. The music became more natural and real yet I thought it was sounding pretty good before. It is mostly in retrospect that I would say it was muffled a bit. Hear what you think! 1 Quote Link to comment Share on other sites More sharing options...

To my ears old caps sound very similar to speaker that are out of phase. 2 Quote Link to comment Share on other sites More sharing options...

I know, the only objective way is to take it out of the XO and measure it, but that´s just numbers. my Cornwall 1980 sounded muffled 10 years ago , the highs and midrange were dull -and the sound was vague , the tweeter or the midrange sounded like 100$ speakers -the HF and mids were lacking , LF was very boomey ---total lack of clarity --capacitors replaced ----and the Highs sparkled and the midrange cleared up with detail - Now oddly , my Heresy 1 -1977 and 1980 are as good as they were 40 years ago , I know the caps are old , but damn do these speakers sound amazing and I am hooked on that sound --- 4 Quote Link to comment Share on other sites More sharing options...

Sancho Panza Posted March 3, 2021 Share Posted March 3, 2021 JEM Performance Audio: AA Crossovers, with Sonicaps, from my 1980 La Scalas. Sent the wife & son to the .9 of a mile away UPS Store. They wouldn’t take cash, so they had to go 6 miles away to ship. In order to insure for the minimum $300 recommended by Jim, UPS insisted on packing themselves. Shipping cost to Jim $35. Please note, his preferred carrier is FedEx; but, it’s not convenient to the house. So, I suspect return shipping will be less. His pricing to me will remain between us, unless he sez it’s OK to disclose...but, was inexpensive, at first appraisal... 1 Quote Link to comment Share on other sites More sharing options...
