Key Features
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 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.
