Combining a large 44-inch XStat CLS electrostatic panel with dual powered 8-inch woofers, the Impression ESL 11A delivers the remarkable clarity, precise imaging, and effortless dynamics that define world-class high-end audio.

Whether reproducing delicate acoustic performances, powerful orchestral recordings, or demanding movie soundtracks, these speakers reveal every nuance with extraordinary detail and realism.

Legendary Electrostatic Performance

At the heart of the Impression ESL 11A is MartinLogan's 44 × 11-inch XStat CLS electrostatic transducer, providing an impressive 484 square inches of radiating area.

Its ultra-lightweight diaphragm delivers exceptional transient response, natural vocals, and a spacious, three-dimensional soundstage that brings the listening experience remarkably close to a live performance.

Powerful, Controlled Bass

Each speaker features two 8-inch aluminum-cone woofers driven by dedicated 275-watt Class-D amplifiers, delivering a combined 550 watts of built-in bass amplification per speaker.

MartinLogan's PoweredForce Forward bass technology and sophisticated 24-bit Vojtko DSP engine work together to provide exceptional low-frequency accuracy, extension, and control.

Anthem Room Correction

The Impression ESL 11A is compatible with Anthem Room Correction (ARC), allowing its powered bass system to be optimized for the acoustics of your listening room.

With the appropriate optional calibration equipment, ARC helps achieve smoother, more accurate bass response and better integration with your room.
