mluc Posted December 27, 2019 Share Posted December 27, 2019 About 4 months ago I acquired a 1984 vintage pair of Klipschorns with the original AK-2 crossovers. After some reading I’ve discovered that the AK-2 is not well thought of. So I’m thinking about replacing the crossovers. Does anyone have the AK-2’s and have you thought about replacing them? And will it make a big difference. Also which vendor to use. any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
Toz Posted December 27, 2019 Share Posted December 27, 2019 Well I had Ak2, then converted then to Ak3 for years and years. I decided recently that I would do some experimenting and put the squawker back to Ak2 which is -2db compared to Ak3 squawker level. I left the Ak3 woofer cap (100uf) because it works great. So I guess I have an Ak2.5. and I like it. New caps are in order no matter what. Quote Link to comment Share on other sites More sharing options...
Toz Posted December 27, 2019 Share Posted December 27, 2019 I also think that criticism of Ak2 is overstated. Quote Link to comment Share on other sites More sharing options...

I have AK-2 networks in a pair of K-horns. I replaced the capacitors for the midrange and tweeter section mounted in the top-hat, but not the big ones mounted inside the bass bin door. The speakers sound fine, and when I send a test tone to the speakers and observe the readings on a Real Time Analyzer, everything looks good. 16 hours ago, mluc said: So I’m thinking about replacing the crossovers...

mluc Posted December 28, 2019 Author Share Posted December 28, 2019 Thanks for responding to my questions. I guess I don’t know what I want to change about the sound. This is my first pair of Klipsch speakers so I’m not sure what they should sound like. I just figured after 35 years they might need a little sprucing up. Capacitors maybe.

JohnA Posted December 28, 2019 Share Posted December 28, 2019 We dislike the Type AL and the similar AB and AK, not the AK2. Quote Link to comment Share on other sites More sharing options...
mluc Posted December 29, 2019 Author Share Posted December 29, 2019 So if you had the AK2’s would you replace the crossovers, replace the capacitors or leave well enough alone? Thanks. Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted December 30, 2019 Share Posted December 30, 2019 I would upgrade the components and turn them into AK-3's. A T4A autoformer, a 5mh coil, two 50uf caps for the woofer bin and something else been awhile since I did it. 1 Quote Link to comment Share on other sites More sharing options...
Khornukopia Posted December 30, 2019 Share Posted December 30, 2019 Do you have the K-55M or the K-55V? Quote Link to comment Share on other sites More sharing options...
mluc Posted December 30, 2019 Author Share Posted December 30, 2019 I have the K-55M’s. So if you had the AK2’s would you replace the crossovers, replace the capacitors or leave well enough alone? Thanks. Quote Link to comment Share on other sites More sharing options...

I would also check that the K-55M back cover is tight, as shown in this link, Quote Link to comment Share on other sites More sharing options...
Toz Posted December 31, 2019 Share Posted December 31, 2019 Replace the caps if the speakers have a dull sound to them. Generally speaking, new caps will crispen up the sound of speakers. This assumes that you now have functioning but aged caps in your speakers. 1 Quote Link to comment Share on other sites More sharing options...

IF and when he offers the same here, I wouldn't blanket any assumptions on his behalf. 1 Quote Link to comment Share on other sites More sharing options...
