Replacement for VIFA drivers

Hello everyone,

I got a pair of elipson Melodine 4 from a friend. One of them is fine, but the three drivers of the other one are out.
I have a really hard time finding information on the midrange (Vifa K10MD-09), I only find the K10MD-19 datasheet, but I don't know if they are equivalent.
I found a small datasheet for the woofer (C20WG-09).

Both parts are unfindable for sale, so I'm looking for replacement ones. Do you have any idea on which could do the trick ? As my other speaker is fine, I really would like that they continue to sound the same...

Thank you in advance for you help!

Alex
 
Thank you for your answers, here are mine:
  • I'm in Europe, so buying from the US of australia isn't an option
  • Yes I'm sure that the drivers are faulty, I've tested the crossover and it's fine and I tested the drivers and there is no electrical continuity through the coil

Does the -19 fit into the slotted baffle for the -09 ? Same question for the woofer ad the -19 look more common
