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 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 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

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™Blade construction
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.

Achieving the Laboratory Standard in Your Own Room

In the lab, MartinLogan engineers strive for transparency.
Outside the lab, there’s one wildcard our engineers can never account for: Your
listening room. The unique size and shape of your listening space (and the size
and shape of its contents) can make bass waves do unpredictable things, greatly
affecting a speaker’s overall performance.

For the first time in electrostatic speakers we are
introducing the integration of exclusive Anthem Room Correction (ARC)
technology. By engaging ARC to control the low-frequency curve in relation to
the output of the ESL panel (as seen in this graph), you will experience
performance on par with MartinLogan’s audio test lab.

ARC measures low-frequency sound output in your room and
compares it to optimal response curves that account for spatial anomalies. The
advanced algorithms of ARC then effectively remove the anomalies, leaving only
the ideal standard: realistically blended, natural-sounding bass performance in
your listening space.

By minimizing room interactions with PoweredForce Forward
bass technology and the advanced room correction capabilities of ARC, along
with its unique synthesis of the ESL and bass sections, the Impression ESL 11A
produces perfectly-etched imaging and focus; optimum natural reproduction of sound
at lifelike listening levels; and agile, full-range operation in open air.

Clearly, it is this level of ultimate performance that
separates the merely excellent from a true masterpiece.

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

The bold, forward-moving styling of this AirFrame Blade rail
system, narrow and strong in front, broad and forceful from the side, is a
modern design statement. It never obstructs playable surface area or interferes
with the panel’s dipole sound radiation pattern. It also provides electrical
and acoustical isolation, minimizing intermodulation distortion caused by
vibration and resonance. The flowing lines emphasize the groundbreaking
integration of the panel itself with the compact woofer and amplifier section.
The breathtaking AirFrameBlade design enhances imaging, low-level
sonic detail, accuracy, and speaker efficiency.

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

Controlled Dispersion Sound Radiation

The sound we hear from a loudspeaker is a combination of
direct radiation from it to our ears, and reflections off of room
surfaces—walls, floor, and ceiling. How our brains integrate this information
is far from simple. Depending on the angle of incidence to the ears and the
arrival-time difference between direct and reflected sound, reflections can
either blur detail and stereo imaging, or enhance the natural impression of
depth and openness.

Electrostatic panels, which are true dipole speakers,
produce a nearly-ideal controlled dispersion radiation pattern. They send very
little sound to the sides, thereby minimizing side-wall reflections, whose
short arrival times tend to interfere with the perception of the direct sound.
Their strong rear radiation, however, produces a generous amount of natural,
ambience-enriching later-arriving mid- and upper register information.

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

New Powerful Dual 275-Watt Class-D Amplification
with 24-Bit Vojtko™ DSP Engine

The performance of Impression ESL 11A has been reconsidered
from the ground up. Taking full advantage of innovations like PoweredForce
Forward and ARC Technology, and the integration of the electrostatic panel with
the woofer array, required daring thinking about power and efficiency. Our new
dual 275-watt amplifiers produce clean power, in a small space, more
efficiently than ever before. They enable the effortless delivery of
exhilarating dynamic impact, with plenty of overhead. Superior, reliable Class-D
technology means there’s virtually no energy lost between the amplifiers and
the woofers.

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 enhanced 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
