Martin Logan ESL Expressions 13A in gloss black. These were purchased as a secondary set for my office. They are about 7 months old. They are not getting any use out of them to justify the cost. I have all original boxes and packaging.
A MASTERPIECE OF DESIGN & ENGINEERING. Distilling nearly forty
years of innovative audio design and engineering into a startlingly fresh
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
