I would have thought that to increase the energy out you would need to increase the energy in so that can only come from a bigger aerial (or 2 aerials if your using 2 crystals).
I know that with high impedance headphones 2 or up to 4 K Ohms is normal because of the many turns of fine wire needed to have a useful magnetomotive force to move the plates and create sound waves, would a bigger current or a larger voltage be created from a longer aerial? And is it the current or the voltage that creates the magnetomotive force? any idea ?
