The MartinLogan Motion F20 is a premium 3-way floorstanding loudspeaker that strikes an ideal balance between size and performance, making it equally at home in dedicated two-channel systems and reference-quality home theaters. Equipped with MartinLogan's latest Gen2 Obsidian Folded Motion® Tweeter, a dedicated 5.5-inch woven fiberglass midrange driver, and dual 6.5-inch aluminum woofers, the Motion F20 delivers exceptional detail, effortless dynamics, and deep, authoritative bass while maintaining the natural, transparent sound signature that defines the Motion Series.
The advanced Folded Motion® Waveguide has been carefully engineered to match the dispersion characteristics of the midrange driver, providing controlled 90° × 90° coverage for a larger listening sweet spot and more consistent tonal balance throughout the room. Working together with MartinLogan's proprietary McCracken-Vojtko crossover network, the drivers integrate seamlessly to reproduce vocals, instruments, and movie soundtracks with remarkable precision, low distortion, and lifelike realism.
The Motion F20's dedicated sealed-chamber woven fiberglass midrange driver preserves exceptional vocal clarity while the dual aluminum woofers deliver powerful, tightly controlled bass down to 35 Hz. MartinLogan's Floor Bounce Compensation technology and bottom-mounted Single Cannon Bass Port reduce unwanted floor reflections and improve placement flexibility, allowing the speaker to produce consistent low-frequency performance even when positioned closer to walls than many conventional tower speakers.
Designed with both performance and aesthetics in mind, the Motion F20 features premium cabinetry available in Gloss Black, Walnut, or Satin White finishes, along with bi-wire/bi-amp capable binding posts for maximum system flexibility. Whether used for high-resolution stereo music or as the front channels of an immersive surround system, the Motion F20 delivers the speed, transparency, and dynamic authority expected from MartinLogan's latest flagship Motion floorstanding speakers.
