Need JBL L88 Crossover Schematic

[vifa32144]

After just building cabinets based on the JBL L88 two or three way loudspeakers, if anyone can find the crossover schematics and post them I would be very greatfull.

Here's the tech sheet:

The 88 Plus had a 2000 Hz crossover as a two way and when the M12 expander kit was added it became 1500 and 6000, the same as the L100. To quote the flyer: "Once the M12 Expander Kit is installed, the only difference between an L100 and the 88 Plus will be the appearance of their Sculpured Air foam grilles."

If you are using the same or similar components in a three-way you could use the crossover for the L100, although plenty of people on this forum would question the wisdom/sanity of custom replicating the L100.

If you do a search on this forum for "L100 crossover" you will come up with lots of interesting stuff. One suggestion by Giskard for trying to improve the L100 crossover is to start with the crossover for the L50, as described on this thread:

Are you building a two-way or a three-way?

If you are building a two way with a twelve-inch woofer, I would suggest not doing it and making a three-way instead.

What drivers are you using?

I'm using the original JBL 12'', 5'', and 1.4'' cone drivers. The crossovers will be boxed outside the cabinet, that way I can connect any JBL two way, three way, or other designs.
