This is a pic from my old system. We are moving into a smaller house so I want to replace the JBL scopes with the 816 on end and put the Edgarhorns and Heils on top of it. I am replacing the Pyle drivers that are in the cabs now with Lambda TD15Xs which are all most identical to the Altec 416 which is what, I think, went in these cabs from the factory.
