Martin Logan Electromotion ESL C Centre Channel Speaker

A a high-performance electrostatic centre 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 centre 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 theatre system.

Expanding the Dynamics of Center Channel Performance

By adding a compact electrostatic panel to a centre channel speaker, Martin Logan engineers have succeeded in expanding the performance dynamics of the most important speaker in your home theatre system. Your centre 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 Martin Logan’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 centre channel speaker.

The New CenterForce™ System

Designing a high performance electrostatic centre channel speaker sized to fit into A/V furniture was no easy task. Adding a dual woofer system seemed impossible! But Martin Logan’s skilled audio engineers found a novel solution, and they call it CenterForce.

Instead of taking up space by positioning the woofers on each side of the electrostatic panel, they’ve designed a central slot inside the cabinet for the woofers. Now, the dual woofers reside in a well-braced enclosure located behind the tweeter and electrostatic panel.

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 aluminium 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.

This is a centre channel speaker that delivers a full-range performance, by combining an electrostatic panel with a Folded Motion Tweeter, bolstered by the CenterForce bass system. The compact EM-ESL C goes where you want it, and does what you need, for your high performance ElectroMotion home theatre system.
