MartinLogan Motion MW4-LCR In-Wall Speaker (EACH)

Description

One of the most compact in-wall speakers in MartinLogan
history, the MW4-LCR expertly blends high performance and maximum flexibility.
The MW4-LCR is a true “Left, Center, Right” speaker that can be used as a
front, surround or center channel wherever high quality sound and a small
footprint are desired.

All MartinLogan Motion CI Series speakers feature our
signature Folded Motion Tweeter or FMT. This innovative piece of audio
technology provides incredible detail, precise clarity, clean output and high
efficiency in a small but mighty package. Pairing this tweeter with lightweight
woven fiberglass woofers means that Motion CI delivers a clean and balanced
sound that is perfectly suited for any application. Whether you listen to
music, movies or a little bit of everything, Motion CI gives you a true high-end
audio experience at an affordable price. To round out the assortment,
pre-construction brackets are available for all models, and all in-ceiling
models have square grilles and retrofittable back enclosures available
separately.

The Sound of Invisibility:

Folded Motion^® Tweeters

MartinLogan’s signature Folded Motion Tweeter utilizes an
extremely low-mass diaphragm that “squeezes” air, thus requiring
significantly less excursion than the typical 1-inch dome tweeter. Its folded
design allows for a much larger surface area (compared to that of a regular
1-inch dome tweeter), controlled dispersion characteristics, and vanishingly
low distortion. It’s a miracle of audio engineering that delivers much of the
high-frequency detail, speed and response of a large, dynamic electrostatic panel
in a small space.

This thin-film transducer design packs all the accuracy and
delicacy of an electrostatic panel into a small space. Folding the dramatically
lightweight film into an accordion-like structure increases the surface area,
giving Folded Motion tweeters eight to ten times greater surface area than
typical tweeters. This ideal combination of light and large produces superior
accuracy, extended frequency bandwidth and higher output capability; all with a
faster, more efficient transient response, and virtually zero distortion. In
these characteristics, the Folded Motion Tweeter design can mimic the
performance of a large electrostatic panel in the confines of a more
traditional loudspeaker enclosure.

Woven Fiberglass Cones

All Motion CI speakers feature lightweight woven fiberglass
cones specifically engineered for their application to blend seamlessly with
the lightning speed of our signature Folded Motion Tweeter. No matter which
Motion CI speaker you choose for your room, rest assured they are designed to
provide a consistently high level of performance and can easily be used with
other MartinLogan speakers to make creating the perfect system for your unique
listening space that much easier.

The MartinLogan Sound

MartinLogan Motion CI speakers sound great in any room.
Regardless of the environment, our speakers just sound better, more articulate,
more detailed, and more realistic. With Controlled Dispersion and one of the
most responsive tweeters in the industry, our in-wall and in-ceiling models can
compete with and often exceed the performance of traditional cabinet speakers. MartinLogan

Spring-Loaded Binding Posts

With easy pre-installation access, our spring-loaded binding
posts feature a large 4.5mm wire access hole and connect via banana plug, pin,
or 12AWG bare wire.

Micro-Perforated Grilles

MW4-LCR features an ultra-low profile, paintable,
micro-perforated grilles with no visible bezel for a near-invisible integration
into any wall or ceiling. A series of powerful magnets hidden inside the
speaker quickly secure grilles into place, reducing the risk of warping or
damage during installation.

Proprietary Vojtko^™ Crossover Networks

Vojtko Crossovers are named after MartinLogan’s chief audio
technologist, Joe Vojtko.

His unique approach to crossover design is just as crucial
to MartinLogan’s Truth in Sound as are our innovative electrostatic and Folded
Motion thin-film driver technologies. A Vojtko Crossover isn’t just a set of
design requirements; it’s a philosophy.

Vojtko Crossovers are hand-built from the highest quality
components and avoid overly complex topologies. This crossover has a
straightforward objective: breathtaking realism.

Hand-Selected Components

In designing each crossover topology, we take the drivers
themselves into consideration. Carefully selected drivers, engineered for
specific performance characteristics, are kept within their optimal frequency
range by the custom Vojtko Crossover.

Each crossover is handcrafted using exceptional
polypropylene and polyester capacitors, custom wound and large steel laminate
low-DCR inductors, and double thick PCBs. This precision-tuned network
preserves even the most microscopic sonic nuances while handling the full
dynamics of any source. It’s a recipe for vanishingly low distortion and
seamless driver integration.

The most critical aspect of a Vojtko Crossover design is the
final voicing, always conducted in a real-world environment. This uniquely pragmatic
approach guarantees that even the most amazing MartinLogan loudspeakers deliver
Truth in Sound in any room, including yours.
