Motion MW4-LCR

In-Wall Speaker

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, Centre, Right” speaker that can be used as a front, surround or centre 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 fibreglass 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 utilises 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 Fibreglass Cones

All Motion CI speakers feature lightweight woven fibreglass 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.

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.
