ElectroMotion ESL C

The powerful EM-ESL C is a high-performance electrostatic center channel loudspeaker.

The powerful EM-ESL C is a high-performance electrostatic center channel loudspeaker. With the exceptional mid-range dynamics of an electrostatic panel, the remarkable details delivered by a Folded Motion Tweeter, and the addition of a newly-designed CenterForce dual woofer system, the most surprising thing about the EM-ESL C isn’t its superior performance. It’s that the EM-ESL C is compact enough to fit easily into today’s most popular A/V furniture. With the EM-ESL C electrostatic center channel loudspeaker, you can match the acoustic signature of your ElectroMotion Series speakers and build a truly astounding home theater system.

Expanding the Dynamics of Center Channel Performance

By adding a compact electrostatic panel to a center channel speaker, MartinLogan engineers have succeeded in expanding the performance dynamics of the most important speaker in your home theater system. Your center channel speaker needs to be able to reproduce the finest high frequency details. The midrange must be expansive; to reproduce every whisper of dialogue. Deep bass adds impact to the front-stage effects that anchor the action to your screen. The EM-ESL C accomplishes all this, and more.

The EM-ESL C has a shallow height CLS (Curvilinear Line Source) XStat electrostatic panel wrapped around the front of the speaker enclosure. The gentle horizontal curve of the panel enhances the output of its deceptively compact 114-square-inch radiating area, extending mid-range dispersion patterns and blending the performance seamlessly with your front-stage ElectroMotion loudspeakers.

Just behind the electrostatic panel, in a specially designed housing, sits MartinLogan’s exclusive Folded Motion Tweeter. The low-mass diaphragm of the Folded Motion Tweeter minimizes distortion, and its short excursion length reinforces its lightning fast high frequency response. The 1 x 1.4-inch Folded Motion Tweeter in the EM-ESL C has a total diaphragm area of 9.2-inches, with the ability to reproduce precise details; one of the most important jobs of a center channel speaker.
