Expression ESL 13A
What makes a masterpiece? Is the “Mona Lisa” just a picture of a woman smiling, or is there more to it?
We consider something a masterpiece when uncommon skill and artistry shapes familiar elements in an unexpected way, revealing an essential truth.
For MartinLogan, the essential truth revealed by our skill and artistry is audio realism. Fittingly, our next generation of electrostatic loudspeakers debuts with the new> Renaissance ESL 15A. Three decades of audio design and engineering innovation, distilled into a startling fresh loudspeaker ideal.

The Art of Emotion in Audio
The Expression ESL 13A is part of the Masterpiece Series. It features a dual 10-inch woofer system with ARC-honed performance, for perfectly blended low-frequency response. The groundbreaking integration of this woofer array with MartinLogan’s signature 13-inch wide XStat CLS Transducer, coupled with a powerful dual amplifier section, delivers an expressive and dynamic audio experience, with less coloration. It reveals the pure emotional impact of your audio.
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. The panel is reinforced with rigid ClearSpar™ spacers, keeping an exact level of tension on the vacuum-bonded diaphragm without obscuring the beautiful see-through design. Add the slender, pointed-arrow design of the new AirFrame™ Blade construction; a powerfully evocative composition creating a harmonious connection between the panel and its woofer cabinet.
Now notice some radical refinements: Inspired by our own breakthrough design, we have reinvented the Expression ESL 13A woofer section, powered by new dual 300-watt Class-D amplifiers, and controlled by a 24-Bit Vojtko™ DSP Engine and ARC™ (Anthem Room Correction).
Using two 10-inch laser-engineered low-distortion aluminum cone woofers in independently enclosed compact chambers, exclusive PoweredForce Forward™ bass alignment technology controls the interaction between the rear-firing woofer and the wall behind that woofer. With smart phase-shifting logic, we minimize the effect that wall has on bass information that might bounce back into the listening room. This uniform frequency response results in realistic bass effects you can feel. It’s one more way MartinLogan innovation improves your listening experience in any room.
