JBL crossover ID

[Hbotting]

Found this the second day of an estate sale hidden in a closet behind newspaper stacks and magazines topped with sewing supplies.

The speaker is a JBL D123, tweeter 075, but I cannot ID the crossover. Seems to be a Barzilay style cabinet. There are no connections on the back to attach to, so maybe a project that was never finished or strangely attached through the back panel and closed back up at some point. No midrange. This must have been connected to the Bell mono amp that was there. The speakers that replaced this we Frazier Monte Carlos with the peizo tweeter and no crossover. Those came home also and about 30 board feet of black walnut lumber.

I had time to take the crossover off today and look things over. Seems that the crossover is the n2400 with the L-pad off to the side. Will need to add speaker connection to the outside to test it out.

If that's a complete 002 load, the crossover should be an N2400, which is exactly what it looks like, just with its mounting trim removed and pot relocated.

The versions with the separate pot and small square can were the "LX" versions.

Thanks for the replies. It looks like this is a C35 cabinet copy. The plywood doesn't look that great compared to some JBL cabinets I've seen that cost far too much for my budget. I checked the tweeter (ca. 5 ohm), and wired it all up. I tested it listening to some jazz and Duke Jordan's Flight to Denmark has never sounded better. Now I need a second speaker, but I doubt I'll find another this inexpensively any time soon. I can make my own much nicer looking cabinets, but the cost to get a 2nd crossover, woofer, and tweeter is beyond what I can justify spending right now. Patience I suppose.
