Legendary MartinLogan Sound

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.
F.A.S.T. Outrigger Feet
The tower models in the Motion® range are designed with tool-less height adjustability in mind, using the included rubber feet or spikes, which enables the user to effortlessly level the speaker for optimal stability on any floor. Additionally, the built-in anti-vibration properties reduce the transfer of energy from the speaker to the floor, resulting in lower distortion and coloration, providing a more accurate and detailed sound.
Nomex®-Reinforced Kevlar® Midrange
The Nomex®-Reinforced Kevlar® Midrange in the Motion® XT Series offers a perfect balance of lightweight, strength, anti-resonance and anti-ringing properties for unparalleled sound quality. When combined with the Gen2 Obsidian FMT XT, the clarity of vocals, dialogue and instrumental accuracy is unmatched at any volume. The seamless integration with Motion® XT CI products makes creating custom solutions effortless.
Aluminum Bass Drivers
