Born2RockU Posted January 6, 2005 Share Posted January 6, 2005 I need the SCHEMATIC for the .......AK-3 crossover, please. I know there are two sections involved... (the woofer crossover parts) and (the tweeter/squawker parts.) I just aquired the components (thank you TOM ) and need to figure out what components to be eliminated and/or soldered together. The reason : I want to use this for my LaScala center. I would appreciate any help in the search, if possible.. Quote Link to comment Share on other sites More sharing options...

Erik Mandaville Posted January 6, 2005 Share Posted January 6, 2005 If need be, Craig, I can draw a schematic from looking at the network itself. I'd rather not have to do that, though, since I don't have lots of time on my hands now that school has started. If someone here has it, it would be greatly appreciated. I'm guessing you will want to use the variable L-pad on this, right? Quote Link to comment Share on other sites More sharing options...
Born2RockU Posted January 6, 2005 Author Share Posted January 6, 2005 I would hate to take up too much of your time, ERIK. I hope someone here can help ! ....and , of course, I am spoiled w/ the L-Pad....could do without it ! "oh, the air the speaker have w/ the L-Pads" Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted January 6, 2005 Share Posted January 6, 2005 Craig, I have a hand-drawn diagram of the connections, I'll send it along with the lower section. Quote Link to comment Share on other sites More sharing options...

Marvel Posted January 6, 2005 Share Posted January 6, 2005 The attached contains diagrams for: ak-2 ak-3 al big type A Type AA Type AL-3 Type 500-5000 Type DHA2 (from John Albright) Cheers, Marvel Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted January 6, 2005 Share Posted January 6, 2005 I didn't get to Marvels' zip yet but the diagram Al posted is what I have. Instead of two 50's paralled in the lower section it has one big honkin' Aerovox 100uf. I wired mine up without the fuses because I'm easy on gear. If you push your stuff at all I'd add in at least one of the fuses. Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted January 7, 2005 Share Posted January 7, 2005 I am surprised that no one has mentioned that the AK-3 is a Klipschorn crossover network and is NOT designed for the La Scala. You will need to convert it to an AL-3 which is the crossover designed for the La Scala. In addition, the AK-3 and AL-3 are designed to work with the K-55M midrange so make sure that is what you have to work with. 1 Quote Link to comment Share on other sites More sharing options...
Tom Mobley Posted January 7, 2005 Share Posted January 7, 2005 I believe he does have the K-55-M. I wonder what the difference is? Klipsch used the AA interchangably in the LS, Belle and Khorn for years? Is that right? I have not really understood how the AA which works with the 400Hz horn in a Khorn or LS also works for a Belle with a 500Hz horn. Anybody know about this? Is 100Hz just not that much? seems like at a low frequency like 400-500Hz it is quite a difference. The real reason I'm asking about this is because I want to build ALK's for my '60 Khorns, which have a K-500 mid horn instead of the later K-400.

3dzapper Posted January 7, 2005 Share Posted January 7, 2005 I think the Belle used a type AB Tom. Same as the AA with the xover to the squaker raised a notch. Rick Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted January 7, 2005 Share Posted January 7, 2005 When Klipsch went to the K-55M, they changed the AA that had been used in the Khorn, Belle, and La Scala to the AK Series (Khorn), AL Series (La Scala), and AB Series (Belle) the caps were changed from the PIO's to poly type Aerovox caps, not sure on all the crossover points and autoformer tape settings but they all are different from one another in one aspect or another.

Born2RockU Posted January 7, 2005 Author Share Posted January 7, 2005 Frzninvt: ...so how do I timbre match my '95 K-Horn AK-3's w/ my center La Scala ? Quote Link to comment Share on other sites More sharing options...
Erik Mandaville Posted January 7, 2005 Share Posted January 7, 2005 Craig: I'm almost certain the mid-horn is the same is those now in your Klipschorns. I think all the drivers are the same, actually..... Didn't you say that you tried the AK-3 and the timbre was now almost a perfect match?

Erik Mandaville Posted January 8, 2005 Share Posted January 8, 2005 This is great Marvel, thanks for the attachment! I've got some great information saved because of your willingness to share it. Erik Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted January 8, 2005 Share Posted January 8, 2005 Hey Born, I would not stress over it too much. I have the equivalent of AK-3's in my Khorn mains and my center La Scala has one of DeanG's Jensen PIO Type AA's in it and it blends seamlessly. I added the K-401K horn and changed the spring terminal K-55V to a solder terminal version and I cannot tell it from the K-55M's. If you want everything perfect I would use the K-55M/K-401K and the AL-3 crossover in your center La Scala for a perfect match to your AK-3'd Khorns. Talk about a front stage! It's awesome!
