MartinLogan ElectroMotion ESL C Center Channel Speaker (EM-ESL C)

Description

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.

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.

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 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.

This is a center 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 theater system.
