K85Horn Posted June 17, 2013 Share Posted June 17, 2013 I bought a set of 1985 Klipschorns and the original crossovers were updated with aftermarket units. These aftermarket crossovers sound fine and that being said, I would like to try a set of Type A Klipsch crossovers and a set of Type AA Klipsch crossovers to experience Paul Klipsch's "take" on the Klipschorn! My questions are; 1) I have an official Type A schematic but it does not show the model of drivers - my current drivers are Crites CW1526, K-55M and K-77's - does anyone know what "official" drivers are meant to work with the Type A crossover? 2) Is there an "official" schematic of the Type AA available? I want to compare crossover parts of a Type A crossover with a Type AA crossover. I have a used Type AA crossover on the way and am wondering if I can easily convert it to a Type A. Thank you for any information. Greg Quote Link to comment Share on other sites More sharing options...
garyrc Posted June 17, 2013 Share Posted June 17, 2013 The plain old K77 would have been used with both. It is a quality selected Electrovoice T35. I believe the K55M is newer, and used a different balancing network, or maybe it used the AA ?? Ask Crites about the Crites to see what it is equivalent to. Somewhere, there is a comprehensive list of all the changes to the Klipschorn over the many, many years. Someone on the forum is bound to tell you where to find it.

K85Horn Posted June 17, 2013 Author Share Posted June 17, 2013 I searched a bit after my post in the forum and found schematics in a zip file of the Type A & Type AA networks. You are right - the Type AA has tweeter protection while the squawker/woofer sections look identical between the A & AA. This should make it a simple task to try out each of the types to hear which ones I prefer. Thanks for the information. Quote Link to comment Share on other sites More sharing options...

Deang Posted June 17, 2013 Share Posted June 17, 2013 It's late for me and I'm pretty tired - if Dennis doesn't beat me in here first I'll add comments tomorrow. Quote Link to comment Share on other sites More sharing options...
Tony T Posted December 29, 2017 Share Posted December 29, 2017 Just bought a pair of 78' Khorns and already preparing to replace the AA's. Is Crites the best place? I'm really not into replacing caps, etc. I just want to purchase a complete board and install. Also, seeking quality and not yet another "good deal". Thanks for any help Quote Link to comment Share on other sites More sharing options...
tromprof Posted December 29, 2017 Share Posted December 29, 2017 Bob will sell you crossovers that sound like new but original crossovers. He also has the A4500 (?) which lowers the crossover to the tweeter and helps out the K400 mid horn. That requires new tweeters but is worth it IMO. Others such as Dean sell improvements on the old designs. Lots of ways to go about this. Bob is the easiest, and does a nice job. 1 Quote Link to comment Share on other sites More sharing options...
Deang Posted December 29, 2017 Share Posted December 29, 2017 Original parts were somewhat “lossy”, so building with currently available popular capacitors will result in a sound that is more forward than the original voicing. Quote Link to comment Share on other sites More sharing options...

When you first replied in June of 2013 Dean, you said you were feeling tired and would reply "tomorrow." It's four and a half years later and you are just now replying? I hope you got some rest and are feeling better. +++ Congrats on the Khorns @Tony T. Be sure and listen to them with the stock XO's for a month or so before you replace the old Type AA's, see how you like them. I had some Khorns (now gone) from the same year and they sounded outstanding with the stock AA's, which I replaced with A/4500's and some upgraded tweeters, which also sounded outstanding. 1 Quote Link to comment Share on other sites More sharing options...

tigerwoodKhorns Posted December 30, 2017 Share Posted December 30, 2017 You are not getting off that easy. Does the Type A need any adjustment for the K55M or the square magnet K77? Quote Link to comment Share on other sites More sharing options...
Deang Posted December 31, 2017 Share Posted December 31, 2017 Technically yes, but there is so little difference in the output of the various drivers, that from the perspective of actual use and practicality - no. 1 Quote Link to comment Share on other sites More sharing options...
Tony T Posted December 31, 2017 Share Posted December 31, 2017 It seems to me that all original 78' Khorns would, no doubt automatically necessitate new caps. Maybe I'll install them first before removing the old boards and disregarding completely. Is Crites the best place for replacement caps? I don't want to compromise quality.

Deang Posted January 1, 2018 Share Posted January 1, 2018 Bob sells good capacitors, but I personally don't think they provide the best possible sound - I don't think they sound as good as your old capacitors probably did when they were new. However, they're better than what you have now - worn out capacitors. Quote Link to comment Share on other sites More sharing options...
