Hi,
Sitting with a pair of Bang & Olufsen Pentas, at least two mids are out of function and im trying to find new mids.

These have apparently been deleted from the range of B & O, but probably not from production (I hope!?)

Need some help where I can find new ones. (brand new preferably)

As shown in Figure No. 1, two elements probably has been replaced during its lifetime!

Many Pentas are being broken up for parts these days, it should be possible to
find some good used working midrange drivers. Foam rot can be repaired.

Have you confirmed that the drivers are bad and it's not a crossover fault or merely
a lose connection somewhere ?

Just to confirm Martin when I received my Pentas one of them had no working mids and the other had two out. Turned out to be dry joints on the crossover. Amazingly, R1 (I think) in both units had almost completely de-soldered itself on one of it's pins! I put this down to heavy partying!
