WalnutThe MartinLogan Sound
Regardless of the environment, MartinLogan speakers achieve high levels of articulation, detail, and realism. Utilizing exotic thin film technologies and Controlled Dispersion, MartinLogan provides unique and special listening experiences not commonly found in the industry.
Gen2 Folded Motion XT Tweeters
The Gen2 Folded Motion XT Tweeter is the flagship variant of MartinLogan’s signature FMT technology. Elevating the signature FMT to new heights with a 40% increase in surface area, providing higher levels of detail and effortless sound.
Motion Waveguide
Enhances the Controlled Dispersion of the Gen2 Folded Motion Tweeter, blanketing the listening area with incredible detail and precision. Avoids performance robbing room reflections and provides a more consistent sound across a wider seating area.
Controlled Dispersion
Room acoustics are vital, as everything in the listening room has an impact on speaker performance. MartinLogan minimizes these harmful effects by focusing the sound into the listening area, increasing flexibility, clarity, and placement options, regardless of the room’s design.
Kevlar-Nomex Midrange
Motion XT’s Kevlar-Nomex Midrange provides an ideal combination of lightweight, high strength, and anti-resonance for maximum fidelity. When paired with Motion XT’s Gen2 FMT XT, the vocal clarity, dialogue, and instrumental accuracy are unrivaled at any volume.
McCracken-Vojtko Crossovers
The culmination of combining extensive anechoic, in-room measurements, and multiple blind listening tests with the low distortion philosophy of MartinLogan’s signature Vojtko Crossover. Through this process each speaker was refined to achieve peak performance.
Enchanced Cabinet Bracing
If a speaker cabinet isn’t braced properly, it will vibrate or resonate, resulting in masked clarity and detail. This 4th generation Motion XT series features specially engineered bracing to maximize sound quality by minimizing unwanted vibrations and resonances.
Secure Lock Grilles
Stealth mounting tabs securely hold the grilles in place allowing the listener to customize the appearance of each speaker. Creating a unique look; leaving the grilles on, off, or even rotating them to change the grain of the fabric providing maximum aesthetic control.
Threaded For Stands
Threaded inserts on the bottom of the speaker allow for secure attachment to MartinLogan’s matching speaker stand, the STAND25.
