| Content | The K.12.2 powered 2-way loudspeaker operates from a 2000 watt power module. This module delivers ample burst and continuous power for the loudspeaker’s premium drivers. Dynamics processing was built to protect the drivers from damage and keep distortion from the performance. Low-noise fan cooling design of the module allows the enclosure to be used in quiet settings.
Operation is easy right out of the box with an extensive list of factory preset EQ contours including Live, Dance, Monitor, and more. For other applications you want quick access to, use savable/recallable Scenes feature. This can store information such as user EQ, Delay, and input configuration settings for you to cue up at your convenience.
Loudspeaker has two balanced combo XLR/F plus 1/4-inch TRS connectors with independent gain control. The first has selectable MIC/LINE level input, the second has selectable HI-Z/LINE level input. Both inputs connect directly to a pair of XLR/M throughput connectors, allowing signals to be daisy-chained to another audio device. Connect sources such as smart phones, computers, and MP3 players with the included 3.5 mm TRS input jack. Line-level output with mixed signal from all inputs is provided.
Coverage is extremely accurate and handles well in a variety of acoustic spaces with little or no equalization thanks to Directivity Matched Transition and Intrinsic Correction. Directivity Matched Transition ensures uniform response across the coverage area by matching the coverage angle of the woofer at the cross-over frequency with the horn pattern. Intrinsic Correction techniques work to create smooth power response.
Rugged ABS enclosure protects elements of the loudspeaker while giving it a professional and unobtrusive look. Use as either a main PA or floor monitor. Speaker also has ergonomic handles and heavy-duty grille with fabric lining, dual pole cups for 0 or 7.5 degree downward tilt, and integrated M10 fittings to accommodate suspended applications.

| 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. | IsoAcoustics' Aperta Support plate can increase the surface area of speaker stand tops to accommodate the length and width of isolation stands or speakers. IscoAcoustics recommends and provides double sided tape to fasten their support plate but they can also be drilled to any surface if desired. |
