ESL63 Impedance Characteristics.

Planar Speaker Asylum

Welcome! Need support, you got it. Or share your ideas and experiences.

I hope this works. I've never pointed at images in my Gallery. But here goes.
I have done some measurements on a standard ESL63. It has not been used for about 5 years.
The 5 plots reveal how difficult/easy it is to drive these speakers. Those who claim that electrostatic speakers are a largely capacitative load on the power amplifier (and therefore are difficult to drive) should be particularly interested.
Of course the ESL63 should not be taken as typical.
The 5 plots are (I hope) accessible using these links:

Hmm. Easier way, please?
