Motion®: Reimagined
Our most ambitious acoustic and aesthetic development in MartinLogan's 40-year history. Motion® Series defines elegance and performance by leveraging exclusive technologies and decades of experience. The result is a loudspeaker collection that is not just an upgrade of its predecessor, but a whole new level of quality and excellence.
Legendary MartinLogan Sound
MartinLogan speakers are known for their exceptional articulation, detail and realism, regardless of the listening environment. By using advanced thin-film technologies and Controlled Dispersion, MartinLogan delivers a unique and unparalleled listening experience that is not commonly found in other speakers.
Gen2 Obsidian Folded Motion® Tweeter XT
The Gen2 Obsidian FMT XT Tweeter has been upgraded with a larger motor to provide higher output and lower distortion. The FMT XT offers the most effortless and detailed sound in the Motion range with a 40% increase in surface area over our signature FMT. Outside of our legendary Electrostatic speakers, these new tweeters provide our cleanest, most detailed and accurate high frequency presentation to date.
Folded Motion® Waveguide
After an extensive evaluation of nearly 50 design options, the Folded Motion® Waveguide profile was meticulously chosen to harmoniously align with the dispersion of the midrange drivers, resulting in enhanced output. The waveguide guarantees consistent sound quality regardless of the listener's position and minimizes unwanted room reflections. Proper waveguide design is crucial as it helps control the sound's dispersion pattern, ensuring that the sound is evenly distributed across the listening area and resulting in optimal sound quality.
Nomex®-Reinforced Kevlar® Midrange
