Expression ESL 13A is the artful presentation of audio focused solely on intensifying your emotional experience. Featuring a 13-inch (CLS™) XStat™ electrostatic transducer, dual 10-inch PoweredForce Forward™ woofers powered by dual 300-watt Class-D amplifiers, and controlled by a 24-Bit Vojtko™ DSP Engine and ARC™ (Anthem Room Correction).
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. The panel is reinforced with rigid ClearSpar™ spacers, keeping an exact level of tension on the vacuum-bonded diaphragm without obscuring the beautiful see-through design. Add the slender, pointed-arrow design of the new AirFrame™ Blade construction, a powerfully evocative composition creating a harmonious connection between the panel and its woofer cabinet.
Now notice some radical refinements: Inspired by our breakthrough design, we have reinvented the Expression ESL 13A woofer section, powered by new dual 300-watt Class-D amplifiers and controlled by a 24-Bit Vojtko™ DSP Engine and ARC™ (Anthem Room Correction).
Using two 10-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 smart phase-shifting logic, we minimize the wall's effect 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.
