Martin Logan ElectroMotion ESL X Electrostatic Hybrid Speaker

Wow! We are really blown away by the new range of electrostatic speakers by Martin Logan. You will not believe the fidelity of the sound that these produce. If you have not treated yourself to hearing an electostatic panel, or if you experience of electrostats is from years gone by, you need to hear the new range from Martin Logan. 

Electrostatic speakers have long been admired for the totally neutral, low distortion and faithful reproduction of music.  Martin Logan has been at the forefront of this technology and with the latest range of Hybrid electrostatic speakers they continue to impress mightily. The new ESL and ESL-X models adhere to everything learned from the years of research and development at a breakthrough price that is also a highly efficient, easy to drive speaker.

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 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. 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 panel. However, as a natural byproduct of tighter build tolerances, it does increase the visual transparency of the panel. The EM-ESL X's XStat panel is so visually transparent it nearly vanishes when you're sitting and listening.
