Distilling nearly forty years of innovative audio design and engineering into a startlingly freshloudspeaker ideal. Renaissance ESL 15A represents a major evolution of our classic electrostatic loudspeaker. All of the familiar elements are here, alongwith 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™Bladeconstruction.

The powerfully dynamic low-frequency experience is rendered with unflinching accuracy and authority courtesy of dual 12-inch low-distortion aluminum cone woofers, each independently powered by a 500-watt Class-D amplifier, and controlled by a 24-Bit Vojtko™ DSP Engine featuring Anthem Room Correction (ARC™) technology.
