Part of Martin Logan's Masterpiece Series, the Impression ESL 11A combines an 11-inch wide XStat CLS electrostatic panel for midrange and treble with dual 8-inch PoweredForce Forward woofers powered by dual 275-watt Class-D amplifiers. It uses a 24-bit Vojtko DSP engine and supports Anthem Room Correction (ARC) for optimized room acoustics. The electrostatic panel delivers unparalleled detail and transparency, while the powered woofers provide impactful, accurate bass down to 24 Hz. The crossover network employs proprietary Vojtko topology for seamless integration and low distortion. The speaker is designed to disappear in the audio chain, revealing pure emotional impact with wide dispersion, low distortion, and a broad frequency response from 29 Hz to 23 kHz ±3 dB. It features advanced MicroPerf stator technology, ClearSpar spacers for panel rigidity, and AirFrame Blade construction to reduce vibrations. The system is compatible with a wide range of amplifiers and includes custom binding posts and adjustable floor spikes.
