Thompson H-3 Speaker
#18

Bob, really nice job on the base! Give a pic when you get the horn done. If you get 900Ohm on the other coil, I think you are good enough. I think that most of those horn speakers (and even the magnetic cone ones) were about 2K Ohm. Did you ever find more info on that little 1 tube radio in the art deco cardboard case?

Took a look at the earlier disassembly pix of the Thompson speaker. Interesting construction, as it appears that the diaphragm is not metal? I guess that the metal reed moves the diaphragm. Would be neat to compare the sound of this speaker to one with a metal diaphragm. Bet this one sounds better!
