Looking for JBL SVA 1800 crossover schematic

[audiomagnate]

What I really need is the voltage drive, but a schematic would be a good start.

I often resort to the Google path "JBL consumer sheets",for such enquiries, and just went there, and found on the sheet list SVA 1800, not case sensitive... Interesting facts, gotta go back for more, like C12RStudio8, and exploded illustration seems to show single chamber for both bass drivers... and so much more, including the crossover circuit, but no curves.
