MartinLogan Renaissance ESL 15A Specification Sheet

A MASTERPIECE OF DESIGN & ENGINEERING. 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.
