Heritage_Head Posted April 20, 2019 Share Posted April 20, 2019 What do you xo guys think of these? How would it work as a type AA replacement in a la scala 1978 stock? I'm a child as far as my tech experience in the xo know how. So would and why would help thanks.. Aren't those just heresy xo? https://www.ebay.com/itm/2-Klipsch-E-2-Balancing-Network-Crossover-Heresy-La-Scala-Cornwall-TESTED/303063543108?hash=item468ffead44:g:W18AAOSw0qdcZwLy Quote Link to comment Share on other sites More sharing options...

DizRotus Posted April 21, 2019 Share Posted April 21, 2019 You're welcome. I suggest Type AA or Type A. Contact Bob Crites @BEC at critesspeakers.com. 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted April 21, 2019 Share Posted April 21, 2019 To be clear, yes, they are Heresy networks. No, not correct for La Scalas, etc. Bruce 1 Quote Link to comment Share on other sites More sharing options...
Deang Posted April 21, 2019 Share Posted April 21, 2019 You can change the primary cap to 13uF, move the squawker wire to tap 4, remove the electrolytic, and it will be a Type A. 1 Quote Link to comment Share on other sites More sharing options...

Lol some day way in the future I hope ill understand everything you say. 13uf from (AA value) Whats tap 4? Where and what is the electrolytic? Even if I don't understand thanks for the input. In your opinion Dean what is the best la scala stock xo (stock drivers), Would definitely get me to the starters line. thanks Quote Link to comment Share on other sites More sharing options...

I was thinking perfect world keep original xo for posable future buyer. But bobs cap kit is definitely least money route. In your opinion AA or A better?

DizRotus Posted April 21, 2019 Share Posted April 21, 2019 Sonically they’re the same, IMO. Type AA has Zener diodes to protect tweeters. You don’t need that. 1 Quote Link to comment Share on other sites More sharing options...
jimjimbo Posted April 21, 2019 Share Posted April 21, 2019 Sonically they are not the same, IMO. Do an A/B test. The AA is smoother and less harsh. With more robust tweeters, you don't need the zeners, but that's not the only difference. 2 Quote Link to comment Share on other sites More sharing options...
Dave A Posted April 21, 2019 Share Posted April 21, 2019 I just used a set of E crossovers to build an AA. Change the buss wire to all odd number terminals on the barrier strip, (if I am remembering wrong I am sure someone will correct me here but I don't have it in front of me) add a 13uf to the two new 2uf's and you will already have a correct autoformer and coil. I use better aftermarket tweeters so I just scrap the zener's and take them out. There was also a set of AA's recapped with Sonicaps for sale on EBay yesterday for around $199 which was a better buy than buying something you have to fix up. That E2 is not like the E and don't get it. 1 Quote Link to comment Share on other sites More sharing options...

Dean you need to take a good look at the E-2 schematic. 1 Quote Link to comment Share on other sites More sharing options...

BEC Posted April 21, 2019 Share Posted April 21, 2019 There is much more to that than Dean said. I could probably build a type A crossover from scratch quicker than I could turn an E-2 into a type A. Lots of rewiring on the terminal strips (which are fragile by that age and likely to break) and also the inductor is wrong value and would have to be replaced. And with what the guy is selling that pair of E-2 for, probably cheaper to buy a new pair of type A. 4 Quote Link to comment Share on other sites More sharing options...

And that's exactly WHY I bought brand new Type AA crossovers for my 1979 La Scalas! Because "brand new" 2019 has guaranteed MORE longevity than the older original crossovers! John Kuthe...
