Martin Logan ESL9

Our next generation of electrostatic loudspeakers with three decades of audio design and engineering innovation, distilled into a fresh and surprising loudspeaker ideal.

MartinLogan is a renowned American manufacturer of high-end loudspeakers, known for its electrostatic and hybrid models. Founded in 1979 by Gayle Martin Sanders and Ron Logan Sutherland. In 1979, Gayle Martin Sanders and Ron Logan Sutherland created MartinLogan to design a reliable and practical electrostatic loudspeaker, solving the problems of safety, space, bass and durability. In 1981, the MartinLogan Monolith became the first commercially viable electrostatic loudspeaker, winning numerous awards and patents. During the 1980s and 1990s, MartinLogan launched iconic electrostatic models such as the CLS , Aerius , SL3 , Quest and reQuest , and expanded its line into home theater.

Classic ESL 9

Consider the Classic ESL 9 your ticket to a life-changing experience with a masterpiece of audio performance. Classic ESL 9 lets you enjoy a life-changing experience with a masterpiece of audio performance. This completely passive design features a 9.2-inch XStat electrostatic transducer (CLS), two 8-inch aluminum Cone woofers, and custom 5-wire, tool-free binding posts. Advanced MicroPerf stator technology reveals more membrane surface area than any other electrostatic panel in this class, effectively increasing narrow panel output. The AirFrame Blade 's ultra-rigid construction reduces performance-robbing vibrations, its shape creating an expressive alignment with the subwoofer.

MartinLogan classic electrostatic technology

Advanced MicroPerf stator technology, which allows for double the exposed surface area of ​​the electrostatic diaphragm compared to a traditional electrostatic panel of the same size. An electrostatic panel reinforced with rigid ClearSpar spacers, allowing an exact tension level to be maintained on the vacuum-bonded diaphragm without obscuring the beautiful transparent design. Add to this the sleek, pointed arrow design of the new AirFrame Blade construction and you have a highly evocative composition that creates a seamless connection between the panel and its subwoofer.

Improvements

We've reinvented the Classic ESL 9 woofer section. We use two 8-inch laser-designed, low-distortion aluminum cone woofers, balanced in an opposing array, one in the front and one in the rear . This design significantly reduces the vibrations inherent in positioning the woofer in the same direction, especially in the 34 Hz ​​to 100 Hz range for an even frequency response, producing realistic bass effects.
