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 Curvilinear Line Source (CLS) XStat 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.
