The Classic ESL 9 features all the familiar elements of MartinLogan’s flagship ESL series 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.
Advanced MicroPerf stator technology, which allows for almost twice the exposed electrostatic diaphragm surface as a traditional electrostatic panel of the same size. A reinforced electrostatic panel with rigid ClearSpar™ spacers, keeping an exact level of tension on the vacuum-bonded diaphragm without obscuring the beautiful see-through design. Add to these the slender, pointed-arrow design of the new AirFrame™ Blade construction and the result is a powerfully evocative composition creating a harmonious connection between the panel and its woofer cabinet.

We have reinvented the Classic ESL 9 woofer section. We use two 8-inch laser-engineered low-distortion aluminum cone woofers, balanced in an opposing array, one forward- and one rear-firing. This design greatly reduces cabinet vibrations inherent in same-direction woofer positioning, specifically in the 34Hz to 100Hz range for uniform frequency response resulting in realistic bass effects you can feel.
