A MASTERPIECE OF DESIGN & ENGINEERING. Distilling nearly forty
years of innovative audio design and engineering into a startlingly
fresh loudspeaker ideal.
MartinLogan unveils the Classic ESL 9, its newest modern Masterpiece.
All the familiar elements of MartinLogan’s flagship ESL series are here,
with some revolutionary refinements. The heart of this exceptional
loudspeaker is its 9.2-inch-wide XStat™ Curvilinear Line Source (CLS™)
vacuum-bonded electrostatic transducer. Advanced MicroPerf stator
technology reveals more of the diaphragm surface area than any other
electrostatic panel in this size class, efficiently increasing the narrow
panel’s output. Ultra-rigid AirFrame Blade construction reduces
performance-robbing vibrations, its shape creating an expressive
alignment with the woofer cabinet. Deep bass is rendered with
unflinching accuracy and authority by dual 8-inch low-distortion, high-
excursion aluminum cone woofers in a beautifully sculpted enclosure.
