JBL 4350A crossover schematic

[theanhngn]

Hi,
With my love for JBL, i have collected all the drivers and accessories for JBL 4350A but for the crossover, i have no clue at all.
Is there anyone who has the crossover schematic for JBL 4350A?

Thanks for reading,

Anh

Sure here you go and search the Lansing Heritage site. Lot's of info. Remember that it's a bi-amp system so the passive 3107 only covers the upper drivers.

On the plans only the ports should differ.

I re-assembled a 4350 in a different way. The original design is asymmetric. So I got rid of the 12 inch. The bass drivers were re-coned with higher sensitivity ones which also allowed greater power handling. The higher frequency response of the bass now mates with the horn. Doesn't go as low, but it is loud. Subs can do the very low end. Currently sitting as main monitors in a London recording studio.
