ummagumma-89 Posted March 11, 2021 Author Share Posted March 11, 2021 Yes thats what one of my woofers look like. Mine is a 1986. The other one is black and has a tear in it. I am going to attempt to upload some pictures of the Tangent-500 interior. They have the k-24-k's too but they are black. Swapped one in my H2's last night and the original was much better for some reason. It must have something to do with that material Quote Link to comment Share on other sites More sharing options...
ummagumma-89 Posted March 12, 2021 Author Share Posted March 12, 2021 (edited) Hope these picture links work All heresy drivers except the passive of coarse. 2 Loose foam things thrown in there. k-24-k's are black. no kevlar ish type material. In the process of adding extra glue and bracing to see if it is possible to get more out of them. Hunting down some interesting techniques that Moray James has tried and going to decide for myself. Anyway as you can see the crossover is a Heresy 2. Seen a post last night where a guy claimed he had crossovers stamped T-400/500. I would like to see a picture of that because from what I have gathered, they were all H2 networks. (for the 500's anyway) No evidence the previous owner had ever opened them up as far as I could guess Also signed "J S" on the top of cab. anyone know anything about that? https://ibb.co/MVtbBPQ https://ibb.co/StZGbmg https://ibb.co/FDm4VWr https://ibb.co/kS0fGQH https://ibb.co/GWGv3fR https://ibb.co/s5vdPbR https://ibb.co/2nKtRFW Edited March 12, 2021 by ummagumma-89 Quote Link to comment Share on other sites More sharing options...

No kevlar or whatever material the H2 had. Stamped k-24k on rear FYI that is a picture of it installed in my H2. Swapped woofer for the experiment. Besides Crites, What other woofers should I be looking at? Im at a crossroad of what to do. I am intrigued by the Super Heresy. I found 1 or 2 posts claiming the specs of crites woofer. from memory the sensitivity was 97db. Anyone know the specs? https://ibb.co/0yG45fb Edited March 12, 2021 by ummagumma-89 Quote Link to comment Share on other sites More sharing options...

billybob Posted March 12, 2021 Share Posted March 12, 2021 Yes was saying last night about a k22 woofer came to mind. Then deleted it. It is 8 ohm and 24k is 4 ohm. Anyway besides this, there is also a K-24-E woofer Just trying to remember the poly cone. Polyurethane, polybutyl. This was chase I was on. Good job and like those 500 cabinets. Clean inside and look like 3/4 baffle. The woofer I had was smooth rubber like and the fainter passive: https://audiokarma.org/forums/index.php?threads/heresy-k-22-k-or-k-24-k-whats-the-difference.596272/ 1 Quote Link to comment Share on other sites More sharing options...

Are you sure the k-24-k is 4 ohm? Everywhere I look it says it is 8 ohms. Will confirm on the original one tommorow, but certain it is 8 8 ohm hi's - 16 ohm mids - 8ohm woofer is what I understood Edited March 12, 2021 by ummagumma-89 Quote Link to comment Share on other sites More sharing options...

ummagumma-89 Posted March 12, 2021 Author Share Posted March 12, 2021 1 minute ago, billybob said: Good fortune... Being extremely new to the scene and attempting to understand how a crossover works, this is throwing a monkey wrench into everything. I was under the impression the k-28 could not be a replacement for me unless I changed the crossover. Forgive me, I am trying to figure this out The weird thing is my brand new amplifier would not feed the tweeters the H2's came with. no sound. Thats when upon further inspection I noticed the tweeters were not original. they were 4 ohm. For the record, I acquired the H2's a month or so ago and amp about a week and a half ago. The tweeters worked on all 3 amplifiers I had laying around here untill the axr-100 came in. This amp prefers A and B together to be ALL 8 ohm speakers. So why would the other amplifiers work and this one wouldnt? Would that not mean the amp goes down to 4 ohms? Any knowledge appreciated as I WANT replacement woofers for the H2's and if I can consider other impedances to "step up" the bass a bit, i'm all for it. Am aware of the cab size, but no harm in trying and not shy to consider a port like the Iv's and claudes super heresy 1 Quote Link to comment Share on other sites More sharing options...

My memory is shot. I was researching info on the tangents and came across his comment. Might have been on another forum. Something I realized immediately is the importance of forums like this for knowledge. I have been digging deep into the possibilities with these speakers on posts that are up to 20 years old. Problem is, none of the pictures everyone shared exist anymore for my generation. This is why I am trying to learn/give any information at all for the next guy who is trying to figure something out. I appreciate all of you 1 Quote Link to comment Share on other sites More sharing options...

ummagumma-89 Posted March 12, 2021 Author Share Posted March 12, 2021 excellent information. something to look into now. I just found out earlier today that the 5000 had different components. More interesting reads, thank-you! 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted March 12, 2021 Share Posted March 12, 2021 I have Heresy IIs from '89 or so, and a good friend has a pair of Tangent 400s, but I don't think I've ever looked at the woofers in his. They sound great, though, and also play lower than the HIIs. I had considered building new birch cabinets the size the the T-400s and moving my parts over. It would be a win, as the bass would be better, stronger cabs, and tweeters more at ear level. 3 Quote Link to comment Share on other sites More sharing options...

I bought a brand new pair of K28 to use in Heresy 1 speakers since I wanted more bass , they are one of 2 spare sets along with the K42 Pro woofers , it was @Daddy Dee who gave me the tip almost 10 years ago , the K28-K does wonders in a Heresy 1-2 and 3-4 ---and by the way , these woofers are no longer easy to come by , klipsch pulled the woofer from the H2 to H3 kits a few years ago , and sold it separately 1 Quote Link to comment Share on other sites More sharing options...
