Commercial Air Speaker Designs

Below lists all of the commercial air speakers that I am aware of, along with as much detail as I have been able to find. Information on some of the models is very sketchy, but anything I have is presented here. Please let me know of any glaring errors in need of correction, or if you have more information.

To qualify to be here, the loudspeaker must have been sold to the public at some point - prototypes or demonstration models are in the theoretical section.

Out of all of these I am only aware of two serious, complete designs that are currently available to purchase - the Acapella Ion TW-1S and the Lansch Corona, both plasma tweeters.

There are various places on the web that have good information about certain models and I have tried to link to as many other sources as possible. Listed alphabetically by manufacturer.
