MartinLogan Motion MC4

The MartinLogan Motion MC4 is the most compact in-ceiling speaker in the Motion CI Series, combining advanced acoustic technology with a discreet design that integrates seamlessly into any room. Its versatile performance makes it an excellent choice for distributed audio systems, dedicated home theaters, and immersive height-channel applications.

At its core is MartinLogan's signature Folded Motion® Tweeter (FMT), an innovative thin-film transducer engineered to deliver exceptional high-frequency detail, accuracy, and controlled sound dispersion. Its folded diaphragm provides a larger radiating surface than conventional dome tweeters, resulting in fast transient response, high efficiency, and remarkably low distortion.

The tweeter is paired with a 4-inch woven fiberglass cone woofer, specifically engineered to complement the speed and precision of the Folded Motion technology. This combination produces clean, balanced audio with detailed highs and natural midrange reproduction.

The Motion MC4 also incorporates MartinLogan's proprietary Vojtko™ crossover network, which uses carefully selected components to ensure seamless integration between drivers and preserve musical detail across the frequency spectrum.

One of its key advantages is its integrated back enclosure, which helps contain rear sound radiation and reduce unwanted noise transmission into adjacent rooms or floors above. Its low-profile, paintable micro-perforated magnetic grille allows the speaker to blend almost invisibly into the ceiling.

With its compact dimensions and versatile performance, the Motion MC4 is an ideal solution for premium whole-home audio installations, surround sound systems, and Dolby Atmos or DTS:X height channels.
