so how would one go about modifying grenaders plans to be louder? other than just throwing in more power, i dont know how much the circuts and chips can take.
i notice that you have used a large transformer for more power... but curious as to witch way you hooked it up.
i'm sure the killer flyback helps, but is it just the volts that matter? I guess you would need a longer arc to get more sound since that gives it more area to effect...
would a really loud audio signal help or distort it?

It would distort it. And the best way to get "louder" music is simply higher voltage.... A flyback with a higher turns ratio would give a higher output, or you just simply run the half bridge with more voltage.

Well, not necessarily. More voltage will give you a longer arc, but if the signal modulating that arc isn't high enough, then you still won't get much audio power out of it. There are many variables that can affect the sound volume and fidelity of a plasma speaker. From my own experience, a very important part of a good plasma speaker is the modulator. You need to modulate the arc to near 100% without the modulator adding distortion to the audio. If you want a plasma speaker that sounds loud, and has reasonably good audio quality, then plan on spending considerable time and money on putting together a high power flyback driver and high power modulator. If all you can afford is a 555 driving a single transistor to power the flyback, then the results will be very disappointing. Of the many plasma speaker projects on YouTube that I've seen and listened to, very few of them sound good, and many of them sound wimpy, weak, and/or distorted.
