Gen2 Obsidian Folded Motion Tweeter S
The Gen2 FMT S offers effortless performance, unmatched by conventional technologies. By folding thin film material, MartinLogan can pack more surface area into a small space providing incredible detail and clarity sure to bring your favorite content to life.
Folded Motion Waveguide

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.
Aluminium Midrange and Bass Drivers
Using trickle down technology from MartinLogan’s own Motion XT and Motion Series, the Motion Foundation Series uses Aluminum cone woofers to maximize clarity, detail, and output.
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.
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.
