help with m19 crossover wires

[juniper]

On the XO, Altec never used a third lug on the 19 crossovers, probbaly because it blends the mids and hi's, I think there's a mod where the third lug can be used but I'm not sure where I read about it, probably a Zilch mod?

Thanks Altec best, when I have a chance I will de solder the one wire and see if it is an improvement. Thanks again for the info!!! I have a funny feeling you are right about the "MOD" the previous owner liked JBL stuff and Altec stuff. Thanks again!
