p.dow Posted January 25, 2007 Share Posted January 25, 2007 hello - i have done a little parusing here with an eye to updateing my crossoverboard. at first i was just going to replace the tired capacitors, but then i figured i would just go ahead and do the AK-2 to AK-3 update. steve at klipsch emailed me the AK-2/AK-3 schematics. now i think it makes better sense to just make my self a new AK-3 board and then save the old AK-2 for something else. i would like to just get all the parts at one place. i have a 2007 parts express catalog but the solen metalized polypropylene caps do not come in 50uF (they have 47 or 51) and do not come in 13uF (they have 12 and 15) (page 156 of the parts exp. catalog). so i am wondering what to do in this regard ? the same with the inductor coils i dont see the exact replacement for 125uH and 500 uH ! i dont see the equivilant in the air core inductors (page 157)? nor am i sure of the best guage? i am also wondering if can use the "Q inductor" for 4mH and the 5mH magnetic core inductor ? (page 159) thanks in advance for any comments/input. paul dunedin, fl Quote Link to comment Share on other sites More sharing options...
BEC Posted January 25, 2007 Share Posted January 25, 2007 You also need an autotransformer. I have all the parts for the AK-3. Send me an email. Bob Crites bobcrites@mac.com Quote Link to comment Share on other sites More sharing options...
p.dow Posted January 26, 2007 Author Share Posted January 26, 2007 right . i forgot to mention that (the autotransformer..... klipsch has'em too...) bob - thanks for your information on your AL-3. for someone like myself who wants to learn/experience -the do-it-yourself aspect of klipsch enjoyment ...... your system deserves consideration, most definitely. paul Quote Link to comment Share on other sites More sharing options...
lorcoll Posted January 26, 2007 Share Posted January 26, 2007 Paul, I have noticed no improvements to change the AK2 with the AK3. Now I have the AK2 in my system and I am very happy with them. Lorenzo. Quote Link to comment Share on other sites More sharing options...
p.dow Posted January 26, 2007 Author Share Posted January 26, 2007 hello lorenzo -thanks for your note. what i am wanting is a greater mid-punch/fullness/robustness when the drummer hits a good cymbal there is a lack of life of clarity of sparkle . sounds that i have heard on anothers khorns, and other speakers. in speaking with steve at klipsch - he listened to my discription (above) and summed it up.... 'its as if someone has a pillow over the front of the speaker sometimes'... thats kind of it. he suggested changeing out the 20+ year old capacitors.... i think the speakers are basically ok so i dont want to go there until i feel the crossover is optimized. thanks paul Quote Link to comment Share on other sites More sharing options...
