I have a similar horn speaker in silver colour. I was wanting to sell it. Does anyone know what it might be worth? It has a Resonophone label on it.

In reply to Barry Browning. Can you not just buy a modern p.a horn driver with the right throat diameter for your horn? This will drive from a modern amp. Or are you trying to get the sound of the original driver as well as the original horn?

Hi
Sorry that should read 195-A Fada radio
I just bought a Fada TFR radio model 195-A
I’m not sure what type of speaker would work with this radio.
Do I a horn speaker for this radio or something else?

It’s a lot simpler to open the old speaker between the base and the horn and then install an 8-ohm 3-inch cone speaker in the base. You’ll get the horn sound with a speaker matched to your modern equipment.

In reply to Bruce.

WRONG! They DID use a permanent magnet – it was just a primitive one. Electro-dynamic speakers, using a field coil and a voice coil, did not come into common use until the late 1920’s, after the horn became pretty much obsolete. The magnets were made of “magnet steel” (an engineering steel with a high amount of cobalt, and smaller amounts of aluminum, nickel, or copper), and were nowhere as good as modern rare earth or ALNICO magnets, but that IS what was used, in early headphones, horns, and in early cone speakers like the Atwater Kent Model “E” and the Peerless Reproducer. The incoming current had NOTHING to do with magnetizing the magnet itself – in fact, that current was quite weak, and was intermittent or pulsating DC (since it was the sound output).

I have an Atwater Kent Model “M” horn speaker, which goes with my Atwater Kent Model 35 radio (made in 1926). The magnet was, indeed, weak, but it does NOT require high voltages to remagnetize these! Just wind a coil of heavy wire around the old magnet and use a car battery. Be mindful of the magnet’s original polarity (test with a compass), and do a test on a metal bar – the direction you wind the wire in affects the polarity, and if you get the polarity wrong the speaker may not work right and you’ll have to start over again…

Nice project but you are in error about the PM magnet. They did not appear until the mid 40’s. They speakers magnets were charged in part by the output, and when they became too weak the horseshoe magnet would be removed to run an electric current through it to remagnatize it.
