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.

Extraordinary sound from incredibly small cabinets. These stylish and discrete wide dispersion speakers offer superb integration in any home and are designed to match perfectly with your choice of Minx subwoofer
Balanced Mode Radiator (BMR) technology affords Minx to be ultra–small and discreet, yet still offer the audio performance of a traditional box speaker. Unlike other style systems, which display obvious separation between the source of bass and higher frequencies, Minx sounds truly integrated for the purest possible sound. The Minx Min 12 measures just 3.1" square, but thanks to its 2.25" BMR driver, it delivers power and refinement that defies its size. The compact speaker offers a variety of prime placement options with a standard 3/8" speaker mount. The BMR driver technology used in Minx gives the system an incredibly wide dispersion of sound. This allows Minx to be placed almost anywhere in the room and still sound fantastic wherever you may be sitting. Minx features traditional 5–way binding posts, meaning that you can use standard speaker cables of your choosing rather than having to put up with yards of cheap, unwanted umbilical cable. Perfect for preconstruction builds, where you can make all of your speaker runs with the perfect length of cable. Unlike many style speaker packages which use low quality spring clips or custom cabling, Minx offers universal connection to any home cinema receiver or amplifier with an ingenious speaker terminal design, which can be removed to support 4mm banana plugs.

The compact, 14" Tall Aon 3 Bookshelf Monitor incorporates a 7", High-Definition, Multi-Vaned Phase Plug (MVPP™), cast-basket Mid-Bass Driver, coupled to two 8" Inertially-balanced side-mounted Low-Frequency Radiators and the GoldenEar High-Velocity Folded Ribbon Tweeter (HVFR™).
The BRX, Aon 2 and 3 bookshelf speakers are exceptionally compact, ultra-high-performance speakers that were originally developed for use as nearfield monitors in professional mixing applications. The design goal was to produce modestly-sized shelf or stand-mountable bookshelf speakers that would achieve accurate high-definition sonic reproduction, with superb three-dimensional imaging, comparable to that achieved by GoldenEar’s award-winning Triton Towers. The new BRX was specifically developed incorporating technology developed for the Triton Reference in order to achieve reference level performance. Although they don’t have quite the awe-inspiring bass of the floor-standing Tritons, great care has been taken, and extensive technology has been incorporated, to ensure that the BRX and Aons can deliver a remarkably satisfying full range listening experience without the need for a separate subwoofer.
Both the BRX and Aon models incorporate GoldenEar-designed cast-basket bass/midrange drivers with technology derived from the midrange units developed for the Tritons. The BRX driver is actually almost exactly the same as the 6" driver used in the Triton Reference. In addition, they all use extraordinary and costly High Velocity Folded Ribbon (HVFR™) high frequency radiators. And the BRX uses the same tweeter developed for the Triton Reference. Lastly, each BRX and Aon model utilizes two side-mounted planar low-frequency radiators in an inertially balanced configuration in order to properly load the bass/midrange drivers for an open, box-less midrange, while also contributing to their’ remarkably extended bass for such small enclosures.

| With the ElectroMotion ESL, Martin Logan has created the world's most affordable high-performance hybrid electrostatic loudspeaker, with a legendary CLS™ XStat™ transducer and an 8-inch woofer to deliver ideal home theater front/surround sound.
ElectroMotion ESL
The ElectroMotion ESL represents a bold new direction for electrostatic loudspeaker design. Featuring a full-sized 34-inch tall curvilinear XStat™ electrostatic transducer and a superbly integrated high-performance woofer, the new EM-ESL performs more like a mini-flagship than an entry level audiophile speaker. Designed for both 2-channel music enthusiasts and those seeking the worlds most articulate and dynamic multi-channel home theater systems, the EM-ESL is the most compelling 'affordable' audiophile-grade speaker ever brought to market.
The ElectroMotion ESL (EM-ESL) represents a brave new direction for electrostatic loudspeaker design. Featuring a full-sized 34-inch tall curvilinear XStat™ electrostatic transducer the new ESL performs more like a mini-flagship than an entry level audiophile speaker. Long time MartinLogan enthusiasts are sure to describe ElectroMotion ESL as the second-coming of the legendary Aerius electrostatic speaker which debuted in 1992 and went on to sell in record numbers. The new ESL, however, boasts 40 percent more radiating surface, a superbly integrated and authoritative bass performance, and a sensitivity rated at 91dB. In addition, the ESL is capable of being effortlessly powered by both receivers and high-end amplifiers alike.
ElectroMotion ESL's XStat electrostatic MicroPerf panel is housed within a radical aluminum and composite AirFrame™ similar to those found on MartinLogan's flagship products. AirFrame technology rigidifies the electrostatic panel without obstructing playable surface area or interfering with ambience enriching dipole sound radiation. At the same time, an AirFrame provides electrical and acoustical isolation, minimizing intermodulated distortion caused by vibration and resonance while enhancing imaging, low-level sonic detail, accuracy, and efficiency. MicroPerf design optimizes the individual holes of The EM-ESL's electrostatic panel. MicroPerf design substantially increases diaphragm radiating area, compared to early generations—without compromising structural integrity. The resulting increase in output capability and efficiency allows The EM-ESL's panel to enjoy a substantial leap in bandwidth and dynamics without growing larger. For example, The EM-ESL's XStat electrostatic panel features 129 square inches of sound radiating surface on both the front and back and a sensitivity of 91dB into 6 Ohms. The Aerius, well received its day, only had 93 square inches and a sensitivity of 89dB into 4 Ohms.
A unique XStat™ transducer was developed for the ElectroMotion ESL to reduce the gauge thickness of the electrostatic panel's steel stators. The reduced gauge does not alter the performance characteristics of the panel. However, as a natural byproduct of tighter build tolerances, it does increase the visual transparency of the panel. The EM-ESL's new XStat panel is so visually transparent it nearly vanishes when you're sitting and listening.
Controlled Dispersion Sound Radiation
Another key attribute of the ElectroMotion ESL is its naturally dipolar radiation pattern. A true dipole, The EM-ESL radiates sound with equal intensity from the front and back of its diaphragm, but the outputs are in opposite phase. As a result, sound waves rippling out toward the sides meet at the speaker's edge and cancel. That and the relatively large size of the ElectroMotion ESL's electrostatic panel cause output at the sides to be very low relative to that of a conventional loudspeaker, which in turn minimizes side-wall reflections that tend to muddle sonic detail and stereo imaging. While the reduction in output to the sides contributes to the astonishing clarity for which electrostats are revered, the energy reflected off the wall behind the speaker opens up and deepens the sound.
Superb Bass Integration
To seamlessly blend audio output from the high- and mid-frequency electrostatic panel to the low-frequency woofer the ElectroMotion ESL features a proprietary Vojtko™ topology filter utilizing custom air core coil and low DCR steel laminate inductors, polyester film capacitors in series, and low DF electrolytic capacitors in parallel.
A precise 8-inch high-excursion, perfectly balanced, audiophile grade, doped fiber cone woofer was custom designed exclusively for The EM-ESL by MartinLogan's in-house engineering team. This woofer precisely optimizes cone suspension and magnetic flux field to produce high levels of bass output and simultaneous precise midrange. The custom woofer's rigid light-weight diaphragm eliminates cone flexure and minimizes response time to achieve remarkably low-distortion approaching that of MartinLogan's award-winning electrostatic panel design.
Easy Connections, Solid Adjustable Footing
Convenient push-style speaker terminals and curved inserts help guide speaker wire effortlessly into place. The rubber end caps on the terminal are also removable for the use of banana plugs instead of bare wire. The EM-ESL is supplied with sturdy, 3/8-16 ETC™ spikes, which can be used to fine tune vertical wave launch, enhance stability on thick carpets, and create tighter coupling between speaker and floor to provide a tighter and detailed bass performance. Each spike is conveniently covered by removable rubber end caps if you prefer not to use spikes. |
