Plasma ion tweeters are an evolution the “singing arc”, invented by William Duddells 1900. He basically reworked a carbon arc lamp – which were known for being fairly noisy.
Now, William found that by varying the voltage to the arc, it changed the sound that was produced…. Bingo.
Much later a fellow by the name of Siegfried Klein got involved and tuned it by putting the arc in a small quartz tube. Coupling this to a horn, he was able to produce a speaker and even a microphone.
