    MartinLogan ElectroMotion ESL Black Satin Floor Standing Stereo Speaker - EMESLD (Sold As Pair)

    The World's Most Superb Thin Film Transducer Technologies

    The all new ElectroMotion™ Series features both electrostatic and compact Folded Motion™ thin film transducer technologies. This bold loudspeaker series establishes a new benchmark for price verses performance. Pushing thin film transducer technology to its limit, the ElectroMotion Series floorstanding loudspeaker, the ElectroMotion ESL, features the most affordable full-size XStat™ electrostatic transducer ever designed. Voice-matched center and surround speakers will feature the next evolution of Folded Motion technology—MartinLogan's new larger, lower distortion Folded Motion™ XT tweeter.

    Designed for both 2-channel music enthusiasts and those seeking the worlds most articulate and dynamic multi-channel home theater systems, ElectroMotion Series speakers are voice and timbre matched with one another as well as the rest of the MartinLogan line. With audiophile-grade floorstanding electrostatic loudspeakers starting at $1,995 per pair (US), this new series represents the most compelling 'affordable' audiophile-grade speakers ever brought to market.

    XStat™ Electrostatic Panel The front stage for the ElectroMotion Series uses a full-sized 34-inch tall curvilinear XStat electrostatic transducer housed within a radical aluminum and composite Airframe.

    Folded Motion™ XT Our new larger, low distortion Folded Motion XT tweeter boasts a radiating surface 40% larger than those found in the award-winning Motion® Series products.

    CLS™ XStat™ Transducer One of MartinLogan's original breakthroughs, CLS™ (Curvilinear Line Source) technology, has been an essential ingredient of every electrostatic loudspeaker we've produced—and the ElectroMotion ESL is no exception. Proprietary manufacturing methods enable construction of electrostatic panels as cylindrical sections. Their gentle horizontal curvature solves the problem of obtaining good high-frequency dispersion from a large radiating surface without compromising overall sound quality or reliability.

    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 maximizes 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, 1/4-20 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.
