1. You hardly ever/probably never play at full power.
2. Music does not have so much energy up in the treble region where the impedance is lowest so you don't need to supply too much power at the 2 Ohm frequency.
Linked below are some measurements I did of my 57's in the time domain - looking for large coincident voltage and current swings into the speaker.
This post was made after a full Electrostatic Solutions refurb, except that I fitted all the parts but I found out later that I had too much HT step-up so the speakers were likely to be more sensitive than ideal. The link also links to a much earlier post where I did the same thing when the speakers were stock (but old). Both experiments concluded that at the loudest volume I would ever listen, and with the worst case CD in my collection, the lowest impedance is 4 - 5 ohms.
ps. the oscilloscope picture has disappeared from the linked post so I reattach it above.
