Impression ESL 11A

Impression ESL 11A reveal the pure emotional impact of the performance, with nothing between your audio and your ears. Featuring a 11-inch (CLS™) XStat™ electrostatic transducer, dual 8-inch PoweredForce Forward™ woofers powered by dual 275-watt Class-D amplifiers, and controlled by a 24-Bit Vojtko™ DSP Engine and ARC™ (Anthem Room Correction).

IMPRESSION ESL 11A

The goal of the loudspeaker is to disappear into its audio performance. Remove the loudspeaker’s effect and you reveal the pure emotional impact of the performance, with nothing between your audio and your ears.

The Impressionist masterpieces removed the barrier between art and emotion, enhancing the potent feelings their art inspired placing emphasis on immediacy and movement. The Impression ESL 11A achieves this effect with an unprecedented level of audio transparency and realism.

The Immediacy of Exceptional Audio

The Impression ESL 11A is part of the Masterpiece Series. It features a dual 8-inch woofer system, with ARC-honed performance, for a perfectly blended low-frequency response.

Achieving the Laboratory Standard in Your Own Room

In the lab, MartinLogan engineers strive for transparency. Outside the lab, there’s one wildcard our engineers can never account for: Your listening room. The unique size and shape of your listening space (and the size and shape of its contents) can make bass waves do unpredictable things, greatly affecting a speaker’s overall performance.

For the first time in electrostatic speakers we are introducing the integration of exclusive Anthem Room Correction (ARC) technology. By engaging ARC to control the low-frequency curve in relation to the output of the ESL panel (as seen in this graph), you will experience performance on par with MartinLogan’s audio test lab.

By minimizing room interactions with PoweredForce Forward bass technology and the advanced room correction capabilities of ARC, along with its unique synthesis of the ESL and bass sections, the Impression ESL 11A produces perfectly-etched imaging and focus; optimum natural reproduction of sound at lifelike listening levels; and agile, full-range operation in open air.

Clearly, it is this level of ultimate performance that separates the merely excellent from a true masterpiece.
