Martin Logan ElectroMotion ESL X

The ElectroMotion ESL X features a new larger XStat™ electrostatic transducer, with a radiating area over 50in2 larger than the EM-ESL model. Twin 8-inch high-excursion woofers are housed in a non-resonant asymmetrical bass reflex (ported) chamber, in a surprisingly compact enclosure. Woofers have custom-engineered high-rigidity paper cones with extended-throw driver assemblies.

The ElectroMotion ESL X (EM-ESL X) X features a larger electrostatic transducer and dual woofers with increased power-handling capabilities. As the flagship model of the ElectroMotion Series, the X establishes a new benchmark for price versus performance.

The ElectroMotion ESL X features a new larger XStat™ electrostatic transducer, with a radiating area over 50in² larger than the EM-ESL model. Twin 8-inch high-excursion woofers are housed in a surprisingly compact enclosure in a non-resonant asymmetrical bass reflex (ported) chamber. Woofers have custom-engineered high-rigidity paper cones with extended-throw driver assemblies. Component elements within the EM-ESL X replicate the design and performance of components used on many of MartinLogan’s more expensive loudspeakers, such as custom-wound transformers, air-core coils, large steel laminate inductors, polyester, and low DF electrolytic capacitors. Custom 5-way bi-wire binding posts allow for secure wire connections. System Frequency Response is 41–22,000 Hz ±3db. Recommended amplifier power is 20–400 watts per channel. Impedance is rated at 6 ohms (1.6 ohms at 20 kHz); the EM-ESL X is compatible with 4, 6, or 8 ohm-rated amplifiers.

A unique XStat™ transducer was developed for the ElectroMotion Series to reduce the gauge thickness of the electrostatic panel's steel stators. The reduced gauge does not alter the performance characteristics of the board. However, as a natural byproduct of tighter build tolerances, it increases the panel's visual transparency. The EM-ESL X's XStat panel is so visually transparent that it nearly vanishes when you sit and listen.
