Thanks for another very interesting video. I own an early Magnavox speaker which has 4 binding post terminals. 2 are for an output transformer to drive the voice coil, and another pair of terminals which connect to a winding to produce the strong magnetic field. It has the tall horn and the lion emblem. I have used it with my Freed-Eisemann model 50 and it works very well.
@@Radio1920s It is hard to read the brass plate, but it looks like RS C, or R3 C. The C is very clear, but the first part, which is a little way to the left of the C is worn.
Can I suggest a video about early radio advertisers on radio. I know General Mills had a Wheaties jingle that they claim to be the first commercial advertisement on radio. Might be an interesting vid in the future.
Interesting. I have believed the first commercial was for a real estate developer in New York City. It was supposed to have been on the AT&T station WEAF about '22 or '23. I'm always learning something new here.
Airtow, Hugh -The earliest commercials on radio that I know of were on Charles "Doc" Herrold's radio station FN around 1912. I have a video on him if you're interested. The commercials were likely for small local businesses or local events.
Great video! Thanks Dan
You are welcome!
Pridham and Jensen were two of the most important men in the early development of loudspeaker design. Giants in radio and audio.
Agreed!

What is the model number of your speaker?

I'll add your idea to my list, airtow. Thanks for the idea.
