The ElectroMotion ESL X is an introduction to a new world of
high performance audio. Highly efficient, with superbly integrated
bass performance, the EM-ESL X will perform admirably with AV
receivers as well as high-end amplifiers.
Equipped with a larger XStat™ electrostatic transducer than the EM-ESL, the EM-ESL X has
a radiating area over 50in2 larger. Twin 8-inch high-excursion woofers are housed in a
surprisingly small, non-resonant asymmetrical bass reflex ported chamber. Dual audiophilegrade,
doped-fiber cone woofers, custom designed by MartinLogan’s in-house design and
engineering team, optimize cone suspension and the magnetic flux field to produce big
bass output with vanishingly low distortion.
The specially developed ElectroMotion XStat MicroPerf electrostatic panel is housed using
AirFrame™ Technology. AirFrame technology, a composite of aluminum and composite
materials, keeps the electrostatic panel rigid without obstructing playable surface area or
interfering with ambience-enriching dipole sound radiation.
