Several manufacturers made these, with Atwater Kent being one of the most popular. They allowed your radio to be played thru the horn of your phonograph. While this may sound silly to us now, in the 1920s the radio speakers were pretty feeble and rather poor sounding. And most radio sets of the day required that you separately purchase the speaker. For those owners who already had a nice phonograph with a good horn on it, these speaker drivers were a good solution. The speaker driver was less costly than a complete radio speaker, and in many cases the driver sounded better when played thru a good phonograph horn than any separate radio speaker of the day. This was especially true in the late 1920s if you had an orthophonic horn in your Victor console phono. The model number of the A-K drivers indicates the type of phono they were designed to fit. The 5V model indicates that it was designed for coupling to the Victor tonearm in place of the standard phono reproducer. I believe the ones designed for Columbia machines were a model number something like 5C. I don't recall if there were any A-K drivers made to fit Edison machines.
