I am bored at work right now and I was pondering the inner workings of ESLs.
In a conventional cone driver the current and voltage (power) flow through the voice coil and interact with the motor structure's magnet/s to produce the field that moves the coil in and out of the gap. From what I've seen, the average cone driver has an efficiency of a few percent.
So here are my questions:
1) How exactly does an electro-stat. "use" amplifier power?
2) How efficient can an ESL panel be?
3) How does the charge generated by the wall plug interact with the amplifier's signal, if at all.
I know how an ESL works for the most part, but I can't quite wrap my mind around the use of the analog signal out of the amp. It almost seems to me that there would be no difference between giving the speaker 800 watts and giving it 5 watts. In a cone driver that difference makes for stronger magnetic fields..... is it the same for an ESL?
