That is not a field coil screwed on to the speaker. That is the output transformer.
The field coil would be attached to the back. It would act as the magnet you see on the back of modern speakers. It is always i. Line with the center of the speaker.
So either that is some crazy speaker design I have never seen before, or the field coil is straight up missing. I've never seen an EM speaker with the FC removed though.
