Description
MartinLogan 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 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. 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.
NEW ULTRA-RIGID AIRFRAME BLADE DESIGN
Impression ESL 11A XStat panels are joined to their speaker cabinets using MartinLogan’s redesigned AirFrame Blade construction, precision manufactured from an aerospace-grade extruded aluminum alloy. This material, and this exclusive manufacturing process, makes the panels extremely rigid.
CURVILINEAR LINE SOURCE (CLS) ELECTROSTATIC PANEL
CLS technology is an essential ingredient of every electrostatic loudspeaker we produce. Through our proprietary manufacturing method, we have built-in the panel’s gentle horizontal curvature. This unique design enhances the high frequency detail produced by the large radiating surface, without compromising overall sound quality. Notice how the gentle modern curve and perforation pattern gives way to the flat grille of the woofer section.
TURNING UNUSED SPACE INTO BETTER BASS
The depth of Masterpiece Series speaker cabinets was carefully chosen to maximize benefits of both PoweredForce and ForceForward technologies, providing powerful bass with extreme detail. Combined with Anthem Room Correction (ARC™), these advanced bass technologies provide a level of low-frequency precision that is truly unique.
