MartinLogan Classic ESL 9 Floorstanding Speaker - pair
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.
A Classic Masterpiece of Sound ReproductionMartinLogan unveils the Classic ESL 9, its newest modern Masterpiece. All the familiar elements of MartinLogans 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 panels output. Ultra-rigid AirFrameBladeconstruction 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. 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 AirFrameBladeconstruction and the result is a powerfully evocative composition creating a harmonious connection between the panel and its woofer cabinet. Classic Elements, Experienced In a New Way:Advanced MicroPerf stator technology, which allows for almost twice the exposed electrostatic diaphragm surface as a traditional electrostatic panel of the same size.

Add to these the slender, pointed-arrow design of the new AirFrameBladeconstruction and 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 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. |
NewUltra-Rigid AirFrame Blade DesignClassic ESL 9 XStat panels are joined to their speaker cabinets using MartinLogans redesigned AirFrameBladeconstruction, precision manufactured from an aerospace-grade extruded aluminum alloy. This material, and this exclusive manufacturing process, makes the panels extremely rigid. The bold, forward-moving styling of this AirFrameBladerail system, narrow and strong in front, broad and forceful from the side, is a modern design statement. It never obstructs playable surface area or interferes with the panels dipole sound radiation pattern. It also provides electrical and acoustical isolation, minimizing intermodulation distortion caused by vibration and resonance. The flowing lines emphasize the groundbreaking integration of the panel itself with the compact woofer and amplifier section. The breathtaking AirFrameBladedesign enhances imaging, low-level sonic detail, accuracy, and speaker efficiency. | ||
