in my highschool time we build one of these with tremedous power
flat frequency spectrum from 25 Hz up to 28 kHz and flat means flat no dips.

lol yes we should have starting to build them commercially, but did not have a solution against ozone production.

plasma speakers are fun;
<a href="http://www.youtube.com/watch?v=bzND4EF1XIo" target="_blank">http://www.youtube.com/watch?v=bzND4EF1XIo</a>
especially when it covers the full range.. not just tweeters..

the ozone problem can be mitigated by helium but that gets even more expensive...

in all honesty tho... out of all the crazy tweeter designs trying to reach highs that only dogs can hear i've always appreciated the sound of a regular paper cone tweeter (emphasis on paper) as sounding the best..

funny enough the highest reachable frequency theoretical is into the light spectrum, audible however is proven to be from about 5 to above 48kHz for so far you still can speak of audible.
on the low end of the range its the resonance of your body, which can make you very sick, like seasickness what you "hear", above approx. 15kHz the sound is no longer detected by the ears, but still noticeable.
Plasma indeed covers the entire range.

when a speaker makes light thats usually a bad thing ;)

plasma speakers do indeed cover the whole range but so do cheap full range speakers.. like the ones in clock radios.. its a matter of 'how well' the speaker can reproduce the frequency in question... so for low lows the arc on a plasma speaker would need to be frighteningly huge... of course id be overjoyed to see such a thing.. imagine a 6foot tall arc playing classical music and hitting all the notes perfectly.. 


early morning random thought; a house fitted with a fireplace could be a potential 'vent' for the ozone due to the chimney effect.. either hoses can be run from the speaker enclosures or the speakers themselves sat in the disabled and cleaned fireplace itself...

dimension of the plasma speaker has no influence on the range as the frequency is superimposed on the frequency of the spark, the size of the spark has a relation to the volume of output.
the frequency spectrum is considered to be straight linear from low to very high frequency

larger arc = more surface area .. more surface area means louder lows
