Description
MartinLogan ElectroMotion ESL C – A high-performance electrostatic center channel loudspeaker with a Folded Motion tweeter, sized to fit discreetly within any standard audio-video cabinet.
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 NEW CENTERFORCE™ SYSTEM
Designing a high performance electrostatic center channel speaker sized to fit into A/V furniture was no easy task. Adding a dual woofer system seemed impossible! But MartinLogan’s skilled audio engineers found a novel solution, and they call it CenterForce.
This new CenterForce solution allows the speaker to be more compact, and encourages the woofers to produce a generous amount of well-blended deep bass. The CenterForce system in the EM-ESL C features two custom-designed 5.25-inch aluminum cone woofers. Rigid and yet lightweight, this material reduces flexure while minimizing response time. Their efficient construction optimizes suspension and magnetic flux field, further reducing potential sources of distortion. The EM-ESL C grounds its performance in accurate, musical bass response.
