Classic ESL 9 is your ticket to a life-changing experience with a masterpiece of audio performance. This completely passive design features a 9.2-inch (CLS™) XStat™ electrostatic transducer, dual 8-inch aluminum-Cone woofers, and custom 5-way bi-wire tool-less binding posts.
Look at the familiar elements of the classic MartinLogan electrostatic loudspeaker: 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. The result is a powerfully evocative composition creating a harmonious connection between the panel and its woofer cabinet.

Now notice some refinements: 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 significantly 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.
