Diagnosis needed. Crossover or woofer problem?

Pair of Musical Technology Falcon speakers measure 6 ohm one side (as rated) but 9 ohm on other.

Lower woofer on the high impedance side moves when powered but with much less force and excursion than on the other side.
Each has 2 woofers in separate enclosures with tweeter between.

Crossover (4th order I think) has 10 caps and 3 inductors with no visible damage.


Anyone able to diagnose this?
 
Thanks, found tinsel wire severed from coil just below spider. Tried conductive glue fix but still open circuit.
Were I to simply swap out both bass woofers from these 2.5 ways, beyond impedance matching, what else should I consider?
 
Above or below the spider ? - still visible you mean ? is there something to still solder to ?


Buy some tinsel wire and repair



TINSEL WIRE

How good's your soldering skills ? - You'll need some skills but it's do-able , or take it to a pro to try.


Or I see some secondhand MT Kestral speakers complete for £120 for the pair , what size are yours?


You could easily spend £50 per driver on decent new ones....
