CLS XStat Transducer

CLS™ (Curvilinear Line Source) technology has been an essential ingredient of every electrostatic loudspeaker ML has produced, and the ElectroMotion ESL X 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.

DiPolar Radiation Pattern

A true dipole, The EM-ESL X 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 X's electrostatic panel cause output at the sides to be very low relative to that of a conventional loudspeaker. This 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 dual woofer system, the ElectroMotion ESL X 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.
