Martin Logan ElectroMotion ESL X Floorstanding Speaker

The ElectroMotion ESL X features a new larger XStat™ electrostatic transducer, with a radiating area over 50in 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 MartinLogans 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 4122,000 Hz 3db. Recommended amplifier power is 20400 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.

To seamlessly blend audio output from the high- and mid-frequency electrostatic panel to the low-frequency dual woofer system, the ElectroMotion ESL X features a proprietary Vojtko™ topology filter utilizing custom air core coil and low DCR steel laminate inductors, polyester film capacitors in series, and low DF electrolytic capacitors in parallel. The EM-ESL X features dual 8-inch audiophile-grade, doped-fiber cone woofers custom designed by MartinLogan's in-house design and engineering team. This efficient woofer design optimizes cone suspension and the magnetic flux field to produce big bass output with vanishingly low distortion. Rigid and lightweight, the custom woofer's diaphragm eliminates cone flexure, and minimizes response time, to achieve levels of performance approaching that of MartinLogan's larger, more expensive electrostatic loudspeaker models.
