Horn Speaker

The horn & Atwater Kent cone speakers

The horn on the left is the station speaker and is wired to the output of the audio amp.  This is the horn that was made to go with the Radiola 3 broadcast set as well as other early RCA radios.

I actually have 2 of these horns of the same model.  They have a pleasant tone and it is a good speaker to listen to CW or AM phone on.  The driver is original, being a 2000 ohm electromagnetic element.  This allows a direct connection to the plate circuit of an audio amplifier without the need for an audio matching transformer.

The Atwater Kent cone speaker has a bit better fidelity, and it would also work into the amplifier, but that speaker will be paired up with the 20C broadcast set.
