Successors for Focal 5N412/5N411, KEF B110A/SP1003, Audax/Polydax HD13B25 & MHD17B37

[tiefbassuebertr]

Regarded successors to the vintage SEAS bass midrange transducers with xp-polypropylene diaphragms I start already this thread some months ago:
Replacement for SEAS Chassis with XP and Polypropylene Cones

But also for follow types with neoflex/bextrene diaphragms I want to know adequate successors:

If I have right designed crossover networks for this vintage models, nothing of currently available chassis outperform the old ones clearly in all respects concerning sonic quality - only in some few details. Especially in the midrange aera (voice reproduction in low-mid level aera e. g.) it seems, that this old models are very hard to beat (only the crossover network design is for some developers very hard, but no longer for me, because I work with special CAD tools).
Therefore I want to know replacement models with same sonic character from currently production.

Also very interesting to know it would be, addresses of special companies which can carry out remake and replace the voice coil of this loudspeakers, if there are such with destroyed windings through DC in case of failured amplifier power stages without couple capacitor for dc protect.
