Plasma speaker creates sound without the need for drivers. Old news. - Page 3

post #21 of 23
Plasma speakers are a health hazard that actively generates ozone. If it weren't for this fact it would have trickled into products ages ago--the technology isn't new and is at least 40-50 years old.

The only acceptable (non-hazardous) hi-fi solutions are either true ribbon tweeters, or using domes made of beryllium or diamond. In all three cases you are looking at $1000-3000 (distributor cost) per driver. Economy of scale can reduce this, but hi fidelity audio is not in high demand these days, rather convenience and portability so these solutions will remain in the boutique/high expense arena.

I don't see any reason why a plasma speaker would be any better than a conventional one.

Your argument is that the plasma is somehow better. I don't see how you can come to that conclusion- after all, the original sound waves were created by something solid vibrating the air. This exactly how your cone in a box works. You bring up lightening, but that has nothing to do with anything.


So you are saying that creating the sound wave through thermal expansion and contraction is somehow inherently better? Why? Because it doesn't have moving parts? But the original sound did!

Yet plasma sound requires a high frequency "Carrier" to keep the spark lit, which will always create noise and distortion from its harmonics. Unless maybe if you ran it in the gigahertz range, in which case the RFI would have the FCC banging on your door, because it would interfere with wireless (AND wired!) communication for probably MILES.

Plasma sound will, I'm afraid always have the same issues- high voltage hazards, hiss, and questionable volume, and immense RFI. The only way to make such a thing safe is to seal it in an enclosure, which I think would cause a lot more distortion than cone flex! And the ozone would likely attack the enclosure...

I mean, its obviously possible if people are doing it, and its cool. But it has no advantages and a TON of terrible disadvantages. Such as safety. Imagine a speaker that, if you put your foot through the grille, killed you!
