The MartinLogan Motion MW4-LCR is one of the most compact and versatile architectural speakers in the Motion CI lineup, engineered to deliver premium performance while occupying minimal wall space. Its true Left, Center, Right (LCR) design allows it to be installed vertically for left or right channels or horizontally as a center speaker, making it an ideal solution for discreet home theater and whole-home audio systems.
At its core is MartinLogan's renowned Folded Motion® Tweeter, paired with dual 4-inch woven fiberglass woofers that provide fast transient response, detailed high frequencies, and clear, natural midrange reproduction. The Folded Motion design moves significantly more air than a conventional dome tweeter while reducing distortion, creating a spacious soundstage with exceptional clarity for both music and movie soundtracks.
The speaker utilizes MartinLogan's precision-engineered Vojtko crossover network to ensure seamless integration between the tweeter and woofers, resulting in smooth frequency response and consistent tonal balance across a wide listening area. Its high sensitivity of 93 dB allows it to deliver impressive output while remaining compatible with a broad range of amplifiers.
Designed for custom installations, the Motion MW4-LCR features a slim profile, shallow mounting depth, and a paintable magnetic grille that blends effortlessly into any décor. Whether used individually, as a complete LCR array behind an acoustically transparent screen, or as surround speakers in an immersive home theater, it delivers the speed, detail, and signature MartinLogan sound expected from the Motion Series.
