Classic ESL 9

Martin Logan

The new Motion 9 ESL electrostatic speakers are the starting point of the Martin Logan 'Masterpiece' range. This model has all the major features of the reference standard ESL speakers but with a number of intelligent 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 aluminium cone woofers in a beautifully sculpted enclosure.

Martin Logan We have redesigned the Classic ESL 9 woofer section using two 8-inch low-distortion aluminium cone woofers, balanced in an opposing array, one forward firing and the other rear. This design significantly decreases cabinet vibrations inherent in same-direction woofer positioning, specifically in the 34Hz to 100Hz range for uniform frequency response, this gives realistic bass effects you can feel.

Classic ESL 9 XStat panels are attached to their speaker cabinets using Martin Logan’s re-designed 'AirFrame Blade' construction, precision manufactured from an aerospace-grade extruded aluminum alloy. This design doesnt obstruct the playable surface area or interferes with the panel’s dipole sound radiation pattern. It also provides electrical and acoustical isolation, minimizing intermodulation distortion caused by vibration and resonance. 

The Classic 9s are available in 3 finishes, dark cherry, walnut and gloss black.
