Maybe Klipsch themselves could helpo if you put to them in the right manner (i.e. no responsibility for them, "outrageously" prived "aftermarket" drivers they couldn't realistically include in the commercial package, the advent of new components not available in '78, etc the usual corporate bull). Given the cabinet design, one can mathematically model the "ideal" driver characteristics; some people have already done so if I remember correctly. Furthermore, as you already own their "new" model they probably would be ready to help you with one of their earlier products.
Greg....what driver updates would you suggest on the 78'sI seem to remember reading that the units used were from Eminence, but I'm not sure... I searched hi & low for the reference and couldn't find it -- sorry.
