Have a look at the Beginners Guide for an introduction. History takes you through the decades of work that has been done on plasma tweeters (and full range plasma speakers), ion wind and all other massless speakers and related technology.
Design gives details of the types and uses of plasma speaker and related devices, their benefits and problems.
Archive helps you find hundreds of connections to every resource including papers, patents, books and magazines published for more than a century, as well as details of the prototype and commercial speakers.
If you are researching or investigating your own designs of massless speaker you can use this site to get a head start and learn from everything others have done before. It reveals the large variety of work that has already been done and hopefully moves the field further more quickly.
Why massless? Here is a definition of massless when used in the audio world. This website was previously known as AirSpeaker and all of its information is now here and has been expanded on.
"… the speaking incandescent electric lamp, the singing arc, and the talking flame — measures of desperation these were; yet each came in for its share of attention as the search continued" Frederick Hunt, Electroacoustics, 1954
