Crossover schematic
photo/top - specifications - order partsThis is the crossover most likely to be found in production examples:
I found this one in a pair in the field. The woofer crossover is slightly different, and the midrange would be a bit brighter:
This version may have been used in some later production, but probably wasn't. It is very parsimonious with components - the woofers are simply direct-coupled, and one capacitor is doing double-duty as part of both the midrange and tweeter filters:
This next one is interesting, in that the two woofers are wired in series, with the lower woofer being rolled off more sharply. The woofers are also wired backwards in the drawing. This crossover was probably never made:
