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.

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.

New  PoweredForce Forward Bass Technology

PoweredForce Forward bass technology combines two MartinLogan audio innovations: PoweredForce, which allows small enclosures to accurately produce massive amounts of bass, and ForceForward, which significantly reduces performance-robbing front-wall bass reflections.

PoweredForce Forward bass technology uses an advanced crossover topology with phase-timed woofers to minimize destructive reflected energy. By virtually eliminating front-wall bass reflections and working in tandem with the panel, PoweredForce Forward Bass Technology gives you more placement flexibility, and enhances the true audio realism of your sound source.

Turning Unused Space Into Better Bass

Masterpiece Series Cabinet Cut-away

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.

Masterpiece Series speaker cabinet dimensions create an ideal relationship between the woofers, cabinet volume, and amplifiers in their PoweredForce woofer systems. By providing ample internal volume for the woofers (two sealed enclosures—one per woofer) along with powerful amplification, Masterpiece Series speakers with powered woofer systems are capable of reaching the lowest registers with authority while preserving bass detail.

With ForceForward bass technology, the farther apart the woofers are from each other the lower in frequency its beneficial effects extend. MartinLogan’s ForceForward technology has solved a problem (found in nearly all speakers) where low bass frequency soundwaves reflect off the wall behind the speakers and interact with the waves traveling towards the listener. These interactions create non-linearity in those frequencies as they arrive at your ears and bass information suffers from both cancelations and excessiveness that is not accurate to the original sound. By selectively adjusting phasing of output from their opposing woofers, powered Masterpiece Series speakers eliminate problematic bass energy from behind the speakers.

ForceForward also simplifies the task of speaker placement by removing bass energy from behind the speaker and creating a uniform bass launch. This allows Masterpiece Series speaker cabinets to go closer to the wall than previous generations of MartinLogan speakers. As a rule of thumb we recommend placing the rear of the speaker cabinet no closer to the wall than the diameter of its woofer (Renaissance ESL 15A: 12-inches, Expression ESL 13A: 10-inches, and Impression ESL 11A and Classic ESL 9: 8-inches). For an added level of control powered Masterpiece Series speakers incorporate two level controls (at 75Hz and 200Hz) to allow for fine tuning of bass integration.

Additionally, due to their dipole nature, electrostatic panels perform best when placed at least 2.5-feet or more from the wall—a distance that is ideal for the front of nearly any high-end speaker, regardless of driver technology. The depth of Masterpiece Series cabinets lends itself to providing electrostatic panels with adequate distance from the wall, guaranteeing a richly detailed, three-dimensional soundstage.

Impression  ESL 11A

MartinLogan’s dedicated in-house design and engineering team created an extremely precise 24-bit Vojtko Digital Signal Processing (DSP) engine to work in conjunction with these powerful new amplifiers. It gives these speakers the ability to deliver detailed low-frequency performance reaching down to 24Hz. Advanced DSP allows complete control and performance optimization over the low pass filters, woofer equalization and limiting functions, all of which are mapped mathematically in the digital domain.

Complete control of the signal, along with instant response, huge amounts of clean power, and efficient, integrated performance, paints an original picture of lifelike audio performance.

Precision-Built Advanced-Topology Vojtko Crossover

Vojtko voiced, the advanced crossover and electronics in Impression ESL 11A add mid-range clarity to this artful composition. Carefully hand-built using only the finest polypropylene capacitors and air-core coils, the crossover employs MartinLogan’s proprietary Vojtko topology for vanishingly low distortion and seamless driver/ESL integration. This precision-tuned network preserves even the most microscopic sonic nuances while handling the full dynamics of any source.

We’ve also considered the signal you will feed your loudspeakers and have engineered Impression ESL 11A to work well with practically any type of electronics. MartinLogan’s state-of-the-art toroidal transformer and electrical interface engineering ensure an absolutely transparent link from amplifier to electrostatic panel and woofer array. This produces sound of unparalleled purity, precision, clarity, and openness — the next best thing to no speaker at all.
