list of jbl 4320 drivers

[vmax700]

I looked but unable to locate an option list of stock 4320 drivers. i would appreciate anyone that could either list the possible options available. Show me where to find them in the archives. The cabinets are walnut veneer and the owner, not original owner knows nothing about the drivers.If there are questions I can ask the owner to help determine what should be in these particular cabinet, please feel free to mention.thanks

2420 + 2307/2308 (aka 2391?) + 2215, -IIRC-... 800Hz crossover.

available materials also show a 4325 in same box w/ different
bass driver (2205B?) and 1200Hz crossover (voiced differently).
