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 S
The Gen2 FMT S offers effortless performance, unmatched by conventional technologies. By folding thin film material, MartinLogan is able to pack more surface area into a small space. Large surface area, light weight and low excursion means an incredibly fast and responsive tweeter capable of reproducing the most nuanced content with stunning detail and clarity.

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.

Aluminium Midrange & Bass Drivers
Using trickle down technology from MartinLogan’s own Motion XT and Motion Series, the F2 uses the exceptional properties of Aluminium to maximize clarity, detail, and output from the midrange and bass drivers.
