Help Identify JBL Drivers

Does anyone know what model these are?

I'm thinking 2445s because of the diaphragm.

They came out of an organ installation but no tags or stamps.

-Looks- like 2445J (because of the diaphragm).
Haven't checked to compare a 2445 vs 2446 phase plug, perhaps determinable with a flashlight.
Odd there are no markings at all.

That was my leaning as well. I'll see if I can find anything about phase plug differences.
