You can buy new ones from Bob and he would probably just give you the wire you need. Sorry! or buy a pair of these and I'll send you the wire. https://www.parts-express.com/jantzen-audio-025mh-20-awg-air-core-inductor-crossover-coil--255-026 Okay, thanks.

avguytx Posted December 4, 2019 Share Posted December 4, 2019 @Drugolf Here are the AA crossovers I built for my Belle clones with all new parts. 1 Quote Link to comment Share on other sites More sharing options...
Drugolf Posted December 13, 2019 Author Share Posted December 13, 2019 Okay, first one done.....I think. Still need to tie down the tweeter inductor when I find the thingy for it. Used Deang's AA roadmap thread in general. Didn't want to spend teh crazt money though on the 13uF cap, at least for now. If anything looks odd, let me know.

Deang Posted December 13, 2019 Share Posted December 13, 2019 Looking good. Just use some silicone adhesive to hold the coil down. That's going to sound very good (you'll hear what I tell you to hear 1 Quote Link to comment Share on other sites More sharing options...

Drugolf Posted January 16, 2020 Author Share Posted January 16, 2020 (edited) Hey! Just a dumb question. My woofers are are 4 ohm. tweeters 8 ohm and mids 16ohm. Any adjustments needed to the AA to account for this? Or is this the standard configuration for the AA?

The AA has eq for the tweeter and I dont know it your tweeter needs any, so I'd recommend crossing the tweeter at 4500 with a 3rd order Butterworth and putting at least a 1st order band pass on the PD-5 (400 to 4500 Hz) to reduce its 9 kHz response "bounce". The Type A woofer inductor is fine, but a larger gauge inductor could be better. Also try it with no woofer inductor. The higher order tweeter high-pass will make a minor improvement in time/phase alignment. Quote Link to comment Share on other sites More sharing options...
geoff. Posted January 17, 2020 Share Posted January 17, 2020 Is there a schematic for the AA mod in the post from JohnA quoted above? Quote Link to comment Share on other sites More sharing options...
avguytx Posted January 17, 2020 Share Posted January 17, 2020 @Drugolf I've watched the rebuild thread on these over at AK. Your cabinet guy has done some really fine work with those. It might not be too late to make those a "collared top" like the Klipschorn "B" version if you like the "neck" between them. Not my pic but what it looks like. 1 Quote Link to comment Share on other sites More sharing options...

Man, you just keep asking and asking.....😋 I think that this is what you are looking for for the 4500 x over. I think that this is the notch filter on the tweeter.

glens Posted January 18, 2020 Share Posted January 18, 2020 You know, I believe that's the first I've seen the tweeter initial cap shown wired ahead of the mid cap. I've wondered about that since when it immediately follows the mid cap it would be an effective 1.7 uF instead of 2 and wondered whether that was on purpose or not...

Right? As I did above all I want to know is since the tweeters are 8 ohm, mids 16 and the woofer 4 ohm, is there any issue with the crossover as I've built it? And maybe some idea on why these all are different if this is by design on various KHorn models. Quote Link to comment Share on other sites More sharing options...
Deang Posted January 20, 2020 Share Posted January 20, 2020 No. You built it correctly. 1 Quote Link to comment Share on other sites More sharing options...
