Plasma Arc Speaker

Selling my plasma Arc speaker. Works fine playing music. Asking $25

I live just down the road from the space and can usually pop in during evenings.

These are cool. Circa 1970 in HS, we went to Cal St Fullerton for a Science and Engineering fair. The two things stood out: laser holograms on a table with all the mirrors/prisms/lens and beam bouncing around but the one that really stuck out was a gas fireplace where the electrodes were at edge of flame and was used as speaker. It was tinny, but cool (if I can remember 48 at years later, it made an impression. verses: Did I park out front in back?).

Good build!

I’ve always wanted to build one … some of them sound really good for tweeters
