Your drivers impedance will peak at its resonant frequency. Enclosure (size and type) and crossover (not simply the crossover point, but the design of the circuit) will both have a direct effect on the impedance curve of the speaker. Amplifiers (some) like to see an easy load. My ESL-57’s do not present an easy load, and are fussy when it comes to the type of power supplied.
Ralph sent me this link in my thread on the ESL57’s. Found it to be extremely helpful.
