Hi Lee
Well i wouldn't be surprised if it was from a jute box or large console radio. Seeburg was in Chicago as were a number of loudspeaker mfr's.
There was;
Oxford loudspeakers
Cynaudigraph loudspeakers
Jensen Loudspeakers
Heppner loudspeaker (northern suburbs)
And i am sure i have forgotten a few Chicago companies
Also parts mfr's like Alpha products, Nu way and others.
I have to say the twin field coil winding is not as common as 1 winding and based on the basket design, it looks like an American driver, perhaps an RCA or Magnevox.
Here are some sample pictures;

I couldn't see the back cover but Jensen used a cap over many of it's drivers even after going to permanent magnets.
Hope that helps

Thanks so much for the links to photos. It looks most like the Jensen. The basket style looks the same, as does the style of the numbers.
Yeah that's a good bet i think!.
Looks like a nice driver with a magnet return that large.
When I had my Seeburg speaker reconed back in 1981, the tech said it was a Jensen.
