Electrostatic Sound at Its Finest

Its exceptionally lightweight diaphragm reproduces vocals and instruments with remarkable speed, clarity, and natural tonal balance, creating an expansive three-dimensional soundstage.

MartinLogan's rigid AirFrame Blade construction provides structural stability while preserving the panel's open, transparent sound.

Each Renaissance ESL 15A incorporates four 12-inch aluminum-cone woofers powered by two dedicated 500-watt Class-D amplifiers.

With 1,000 watts of built-in bass amplification per speaker, the Renaissance ESL 15A delivers effortless low-frequency performance extending to an impressive 22 Hz.

MartinLogan's PoweredForce Forward technology, combined with sophisticated 24-bit Vojtko DSP processing, helps minimize unwanted room interactions while maintaining exceptional bass accuracy and impact.

Anthem Room Correction

The Renaissance ESL 15A supports Anthem Room Correction (ARC), allowing its powered bass system to be optimized for the unique acoustics of your listening environment.

With compatible calibration equipment, ARC helps deliver smoother, more accurate bass response and improved integration with the electrostatic panel.
