The newer Ti diapgrams are not an exact drop in fit in the older 24202470. The pin holes may need slight filing out.
I would be careful of any old drivers as there are no guarantees.
Mr Widget is right
The scarcity of re cone kits and older drivers is a risk in terms of the original result.
Talk to a JBL service agent like Jands in get them to check all your drivers.
It will eliminate a lot of headaches.
My advice is dont rush it. Its a really big job. Allow 6 months at least.
If you have dont have background in electronics get someone to do the passive crossover, the discrete active crossover and wiring up (me-I accept donations like a case wine)
Dont skimp on the active crossover if you have high expectations
Setting then up can take a while.
But when the are they give the newer systems a run for their money
