ElectroMotion ESL X

Product Overview

The ElectroMotion ESL X builds upon MartinLogan’s thin-film electrostatic heritage with a larger XStat™ panel and enhanced low-frequency authority. Featuring a radiating area over 50 square inches greater than the EM-ESL model, the ESL X delivers increased scale, transparency, and dynamic capability. Twin 8-inch high-excursion woofers housed in a non-resonant asymmetrical bass reflex enclosure provide controlled, authoritative bass performance, while premium internal components mirror those used in MartinLogan’s higher-tier designs.
