MartinLogan ElectroMotion ESL overview

  • 1Description

Achieve a unique audio experience with the satin black MartinLogan ElectroMotion ESL Floorstanding Speaker. It uses an electrostatic transducer to produce high-range and mid-range audio frequencies and has an 8" woofer with a down-facing bass reflex port for enhanced bass. This speaker will handle 20 to 300W of power and is therefore compatible with most home theater and stereo systems.

CLS XStat Transducer
The slight horizontal curvature of the electrostatic transducer is designed to solve the problem of obtaining good high-frequency dispersion from a large radiating surface without compromising overall sound quality or reliability.
Controlled Dispersion Sound Radiation
A true dipole, the EM-ESL is designed to radiate 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 each other out. Additionally, the relatively large size of the electrostatic panel causes 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 reduced output to the sides enhance the clarity of the speakers, the energy reflected off the wall behind the speaker opens up and deepens the sound.
Enhanced Bass Integration
To blend audio output from the high- and mid-frequency electrostatic panel to the low-frequency woofer, the ElectroMotion ESL features a 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. Its 8" high-excursion, balanced, doped-fiber cone woofer is designed to optimize cone suspension and magnetic flux field to produce high levels of bass output and simultaneous precise midrange. The woofer's rigid, lightweight diaphragm is fashioned to eliminate cone flexure and maximize response time to achieve low distortion.
Designed for Easy Connectivity
Push-style speaker terminals and curved inserts help guide speaker wire into place. The rubber end caps on the terminal are also removable for the use of banana plugs instead of bare wire.
Solid, Adjustable Footing
The EM-ESL is supplied with 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 more detailed bass performance. Each spike is covered by removable rubber end caps if you prefer not to use spikes.
