A MASTERPIECE OF DESIGN & ENGINEERING. Distilling nearly forty

years of innovative audio design and engineering into a startlingly fresh

loudspeaker ideal.

Expression ESL 13A represents a major evolution of our classic

electrostatic loudspeaker. All of the familiar elements are here, along

with some revolutionary refinements. At the heart of this exceptional

loudspeaker you’ll find a 13-inch Curvilinear Line Source (CLS™) XStat™

vacuum-bonded electrostatic transducer with advanced MicroPerf™

stator technology and ultra-rigid AirFrame™ Blade construction. The

powerfully dynamic low-frequency experience is rendered with unflinching

accuracy and authority courtesy of dual 10-inch low-distortion aluminum

cone woofers. Each woofer is independently powered by a 300-watt

Class-D amplifier, and controlled by a 24-Bit Vojtko™ DSP Engine featuring

Anthem Room Correction (ARC™) technology.
