Commercial Massless Speakers
Where they sell things
 Below lists all of the commercial massless speakers found so far. Information on some of the models is very scarce, some detail is in the notes and the rest will be in the articles section.  To qualify to be here the loudspeaker must have been sold to the public at some point - prototypes or demonstration models are in the theory section. There are currently only three complete designs that are currently available to purchase - the HYPERLINK "https://www.acapella.de/products/?lang=en"Acapella Ion TW-1S, Lansche Corona and the HYPERLINK "https://www.vaughnloudspeakers.com/products"Vaugn Loudspeakers version of the Ionovac, all plasma tweeters.
