JBL 3-way Build....crossover help/advice
Hello Everyone! I first want to say thank you to all of you and your wonderful contributions to this hobby. I started lurking here around 2019 and soon after started collecting some parts. I have an older thread on a cabinet build, but due to the Rona that project is a bit behind. More on that later....
I have collected drivers and components over the last year and a half, putting a system together. Finally down to working on some crossovers. I am plagued with analysis paralysis, I need some help.
I need a crossover for JBL 2405, 2420w/ Azurahorn, and 2235H 5cuft enclosure. The 16 ohm/118dB 2420 is really throwing me off.
I currently run them via dBx Driverack PA2 and a 6 channel Hypex amp, but really want to switch to passive.
I purchased a pair of these JBL L300/4333 Charge-Coupled Crossover Circuit Boards - One Pair | eBay JBL L300/4333 Charge-Coupled Crossover Circuit Boards. I figured if they were not used on this project they would be handy in the future. They incorporate the Nelson Pass mod.
My question is what do I need to change to that L300 board? I need some attenuation as well.

Once I get home Ill add my driverack crossover points, I run the 2235H at a LP frequency of 461hz LR 36dB roll off, the 2420 bandpass from 774 24dB to 5250 12dB, 2405 at 9.47k up with a boost 13k to 20k.
I'm running the 2420 at -15dB to the 2235H
I also have a Umik-1 and REW handy if anyone needs me to post some data.
Thanks
Nathan
