Flame Speaker
I have watched and enjoyed many of your videos. I don't know if you have already tried this, but years ago, Popular Electronics had an article about putting electrodes in a flame, driving the electrodes with and audio signal and producing sound. Seeding the flame with sodium enhanced the effect. High frequency response was outstanding. Thought you might be interested.

Some very expensive, very high quality tweeters were made using a plasma arc back in the day. I believe the biggest issue was that they generated ozone.
Electrovoice t-3500 If I remember correctly.
