The Expression ESL 13A is positioned in the middle of Martin Logan's 'masterpiece' series. With its dual 10-inch woofer system with ARC-honed performance it features a perfectly blended low-frequency response. The groundbreaking integration of this woofer array with Martin Logan’s signature 13-inch wide XStat CLS Transducer, coupled with a powerful dual amplifier section, delivers an expressive and dynamic audio experience, with less colouration. 

The Expressions feature many of the classic Martin Logan electrostatic loudspeaker elements including the advanced microperf stator technology, which allows for almost twice the exposed electrostatic diaphragm surface as a traditional electrostatic panel of the same size. Like many Logans of old, 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.

There are also many new refinements to the Expression which were not found on older Logan models including the 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 the two 10-inch 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, Martin Logan minimise the effect that the wall has on bass information that might bounce back into the listening room.

The standard finishes of the Expression are gloss black, gloss white, dark cherry and walnut with a number of premium finishes also available on demand including red, blue, silver and more.
