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 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. The groundbreaking integration of this woofer array and MartinLogan’s signature 11-inch wide XStat CLS transducer, coupled with a powerful dual amplifier section, delivers an expressive and dynamic audio experience. It’s an experience of pure audio pleasure.
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. A reinforced electrostatic panel with rigid ClearSpar™ spacers, keeping an exact level of tension on the vacuum-bonded diaphragm without obscuring the beautiful see-through design. Add to these the slender, pointed-arrow design of the new AirFrame™ Bladeconstruction and the result is 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 Impression ESL 11A woofer section, powered by new dual 275-watt Class-D amplifiers, and controlled by a 24-Bit Vojtko™ DSP Engine and ARC™ (Anthem Room Correction).
Using two 8-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 a smart phase-shifting design, 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.
