Distilling nearly forty years of innovative audio design and engineering into a startlingly fresh loudspeaker ideal. Renaissance ESL 15A 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 15-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 12-inch low-distortion aluminum cone woofers. Each woofer is independently powered by a 500-watt Class-D amplifier, and controlled by a 24-Bit Vojtko™ DSP Engine featuring Anthem Room Correction (ARC™) technology.
