Expression ESL 13A is the artful presentation of audio focused solely on intensifying your emotional experience. Featuring a 13-inch (CLS) XStat electrostatic transducer, dual 10-inch PoweredForce Forward woofers powered by dual 300-watt Class-D amplifiers, and controlled by a 24-Bit Vojtko DSP Engine and ARC (Anthem Room Correction).

Audio is both real, and imagined. There is the fact of the sound. And there is the feeling that the sound arouses within us.

This feeling is the inspiration behind the new Expression ESL 13A. Like the Expressionist masterpieces, this artful presentation of audio is focused solely on intensifying your emotional experience. It's a virtually transparent audio performance that transports you to a new landscape of the senses.

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.
