Oh crap, today I tackled the non-performing woofer in the N/S/F door of the car. After the second attempt, I managed to remove the door card without breaking anything and according to the owners' forum, a typical problem for my car is the breaking of cables in the rubber conduit that goes from the body to the door. Prodding the meter probes into the woofer cable on the speaker proved that was not the issue, as signals are reaching woofer terminals OK. Joy of joys, this woofer is pop riveted into the door, so I got to use my new Bosch cordless drill for the first time.
Those rivets put up a hard battle and some of them I had to grind away as they were just spinning in the door, so drilling was not a complete success.
I have never seen a speaker fail in such away before, there are no external visual signs the woofer has suffered any form of damage, no smell, nothing, touching the cone revealed the issue, there was zero movement. Measured the resistance, spot on at 2

so no short circuit of the voice coil, but the cone will not budge, regardless of the amount of force applied to it. I've seen speakers that have been overloaded, melt the voice coil and stick the magnets and they stunk and had either shorted coils or were open circuit, but none of that has occurred here.
Nothing on eBay only the normal woofers from the standard car and 4

and zero luck with any car breakers, my car is a pretty rare best with the uprated Canton stereo. The only place I can find a replacement is in Germany, 50 Euros and thanks to the B word, another 20 Euros shipping and the possibilities of have import taxes on top of that, oh goody.
