Good start Dan!

The JBL phenolic 2" driver is 2482.
I would lower the crossover point as far as you dare, 300Hz or so.
Now the 2226 will do what they are pretty good at.
Later you will likely want to filter the 2445 around 2k.
A 600Hz horn with a 1" driver, hopefully with a sweet diaphragm, I prefer phenolic, will take over.
Some day you may go for a tweeter.
I use a sealed cab from 60Hz with 15"driver, and a subwoofer below.
Alnico magnets plus phenolic diaphragms has given me the most joy so far.
Good luck, and enjoy this trip.
Lots of good information here, and helpful folks.

Hi, I have some experience with the 2482. Sure it can reach 300 Hz but only with EQ. It has a semi hard lower knee slope so you are never going to reach 300 clean. If you have a x-over simulator for passive, or digital EQ, go for it, but I really don't see it reaching 300 with any confident sound.

Maybe one could soften the phenol suspension and add shims to get away from the phase plug - that would be interesting... It was never a high frequency driver anyway.
