MartinLogan Expression ESL 13A hybrid electrostatic speaker Review

Read Here

“The MartinLogan Expression is able to generate high sound levels compared to other electrostatic speakers as the stators are closer to the charged Mylar like material than other brands of electrostatic speakers. The panels were also designed to have twice the radiating area of a traditional electrostatic panel of the same size. From my experience, very loud sound levels were obtained with 6 to 60 watts as measured by my amps wattmeter. The Expression is rated at 91 dB sensitivity and a nominal impedance of 4 ohms. However at 20,000 Hz the impedance drops to .5 ohms. Thus, the speakers may not sound crisp with some tube amplifiers in the higher frequencies”
