Yes I can draw you something up. I think you will laugh.

I just went and pulled the other XO to find it has been attacked too. Again with incorrect parts, this time trying to make it a 3rd order. I think I will put it back to original with new goodies (sans coils) and take it from there.

Strange XO though. 2nd order with an 18 mfd cap on the woofer shunt and the cut off cap for the HF is 6 mfd. I might have thought those a little closer. Both coils are identical, just a big gap in the caps. Perhaps that was Altec's way of introducing a notch? hehe.
