Re: [Sursound] Massless speakers
Are these not the same as the Ionophone speakers, sold as Ionofane tweeters in the 1960s? They were flat from 10kHz to oo!

Re: [Sursound] Massless speakers
Accapella Audio Arts has been making horns with plasma tweeters for a while now. They are some of the largest, and most expensive speakers made. Awesome in thier rediculousness, i'd be afraid that someone would get drunk at my home and mistake them for a sink or a urinal. http://www.acapella.de/en/ On Sun, Mar 25, 2018 at 1:23 AM, Augustine Leudar <augustineleu...@gmail.com > wrote: > Ive been wondering for a while whether it was possible to use > electromagnetic waves interferance patterns to generate sound in 3D space > - the conclusions my physisit friends had was yes - possible - but not > without killing anyone that heard it .Plamsa is a bit different of course > to an EM wave > > On 25 March 2018 at 07:45, Gary Gallagher <g.null.dev...@gmail.com> wrote: > > > Never heard of this.

Re: [Sursound] Massless speakers
Ive been wondering for a while whether it was possible to use electromagnetic waves interferance patterns to generate sound in 3D space - the conclusions my physisit friends had was yes - possible - but not without killing anyone that heard it .Plamsa is a bit different of course to an EM wave On 25 March 2018 at 07:45, Gary Gallagher <g.null.dev...@gmail.com> wrote: > Never heard of this.

[Sursound] Massless speakers
Never heard of this. Using laser plasma as driver for a speaker. Here as weapon - but it would be interesting to hear/see a refined version of this. I'm curious about the spinning disk set up at the end of the video there appears to be some sort of modulation in the sound.
