Hi Dirk,
>I now find that the speaker's voice coil is seized
On a lot of the early Philco spkrs the cone with the voice coil can be removed pretty easily. Unsolder the vc wires at the terminal strip. Remove the screws around the perimeter of the spkr frame and the one in the center. Remove the cardboard ring and gently lift the edge of the paper cone, it isn't glued in just held in by the screws and ring. You may find that wiggling or giving the cone a gently twist to get the vc freed up from the pole as yours is stuck (center piece). Once you get the cone out you'll want to clean out around the pole. It maybe just be dirty or it may have some rust which can be removed w/ some 400G sandpaper. Stick it down into the pole and frame gap and give it a light sand. Vacuum out the pole and reassemble.
Here's a couple of pics of a spkr from a model 80. Cone is badly torn.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
