Awhile back, I bought a pair of Altec 1231 wedge monitors with messed-up XOs. They were originally installed in a church and had line xfmrs and HF attenuators added. The guy I bought them from unhooked the xfmrs and attenuators, and for some strange reason, also removed all wiring and the XO caps and put it all in a coffee can. Shouldn't be a big deal, right?
The 1231 specs say 2000Hz at 12dB/octave with 8 ohm drivers. My problem is that there are two coils and THREE caps. Assuming they used a 2nd order lowpass and a third order highpass gives the appropriate component count, but I can't make the values work out for that configuration. There are two matching 1mH coils, and 3, 8, and 21uf caps.
Can't find a schem, but I did find a picture of one on eBay that verifies I have the right components (too bad the pictures not good enough to see how it's wired!);
Help!
