I got these today on a whim, I guess they need diaphragms, I looked at them and they seem alright here's a picture; no cracks or holes;

at least one dia... might figure out what to do with them before sinking
cash into a new pair ( could go 8-16 ohm nominal, 2440 or 2441 diaphagms,
etc... depends on what you'd use them for/with).
Both diaphragms show big-time stress/metal fatigue....even though they still "work". Just a caveat.
The best, most cost effective choice for JBL replacement diaphragms would be the aquaplas coated D8R2450SL, D8R2452SL($200) or D16R2451SL($198)
Aluminum D16R2440 is $240, D16R2441 is $272. Not as durable as the ti/aquaplas units.
If you're after authenticity, by all means go for the the original spec. If you want better value/performance get the newer units.
