Hello, I know it's an old thread, but wanted to see if it's still ALIVE ! I have a pair of Altec 19s. (just got them, the wires were not hooked up from the crossovers at all). So, I have NO CLUE were to solder the new wires, which ones go where etc.... I want to solder the wires, but do you have a picture of a normal crossover fom the 19s? One that hasn't been altered ? I seen the diagram you made, if I am not mis reading it, very little of the pins are used, some on the back of the crossover, and just a couple in the middle? If they are correct, I will use the diagram you wrote up. It's just a picture along with your positions of wires would help so much since I haven't a clue on how to use a multi meter...lol...Thanks a ton.. Mjclemm....
