About the ElectroMotion ESL

The Martin Logan ElectroMotion ESL is a hybrid electrostatic loudspeaker designed for both music and home theater applications, ideal for medium and small rooms. It features a 34-inch Curvilinear Line Source (CLS) XStat electrostatic transducer that delivers wide sound dispersion, excellent clarity, and low distortion, combined with an 8-inch high-excursion paper cone woofer housed in a bass-reflex ported enclosure to reproduce frequencies below 500 Hz. The speaker includes a high-performance Vojtko crossover network with custom air core coils and capacitors for precise audio integration. It has a frequency response of 42–22,000 Hz (±3 dB), sensitivity of 91 dB, and an impedance of 6 ohms, compatible with amplifiers rated from 20 to 300 watts. The ElectroMotion ESL is finished in Satin Black, weighs 35.5 lbs, and measures 53-1/8" H x 9-5/16" W x 16-1/2" D. It includes an external low-voltage DC power supply to energize the electrostatic panel, adjustable floor spikes, spring post terminals, and a cloth grille. The speaker is praised for its clear dialogue, wide sweet spot comparable to more expensive models, and solid bass performance down to the mid-40 Hz range. It is considered an affordable audiophile-grade speaker that performs like a mini-flagship model, suitable for both stereo and multi-channel home theater systems.
