MartinLogan Motion F20 walnut (pack of 2)

MartinLogan Motion F20 embodies the culmination of decades of expertise in high-end sound reproduction. This 3-way floorstanding speaker combines cutting-edge technology with refined design to deliver an exceptional listening experience. Designed to satisfy the most demanding audiophiles, the Motion F20 stands out for its precision, dynamics, and musicality.

A design combining elegance and functionality

The Motion F20 features sleek, modern lines that blend seamlessly into contemporary interiors. Its meticulously crafted cabinet, available in high-gloss black, satin white, or walnut finishes, reflects a keen attention to detail. With dimensions of 112.7 cm in height, 29.8 cm in width, and 36.2 cm in depth, this floorstanding speaker makes a bold visual statement without overwhelming the space.

The understated and elegant front panel highlights the speakers without unnecessary embellishments. The pleated ribbon tweeter, a visual hallmark of the Motion series, sits at the top of the speaker. It is topped with a carefully designed waveguide to optimize sound dispersion. Below it are the midrange driver and two woofers, seamlessly integrated into the front panel.

The speaker’s base incorporates a downward-firing bass-reflex port, an ingenious solution that reduces placement sensitivity while ensuring ample and controlled low-frequency reproduction. The F.A.S.T. (Frequency Attenuating Stabilization Technology) outriggers provide optimal stability while minimizing unwanted resonances.

Cutting-edge acoustic technology

At the heart of the Motion F20 lies its sophisticated technological arsenal. The Gen2 Obsidian Folded Motion tweeter represents the latest evolution of MartinLogan’s pleated ribbon technology. This unique transducer uses an ultra-lightweight accordion-folded diaphragm, offering a large radiating surface in a compact format. The result is a precise high-frequency reproduction with minimal distortion and exceptional dynamics.

The 14 cm midrange driver features a woven fiberglass cone, a material chosen for its excellent stiffness-to-weight ratio. This diaphragm, mounted in a non-resonant sealed chamber, ensures natural and detailed reproduction of midrange frequencies, essential for faithfully rendering voices and instruments.

For low frequencies, the Motion F20 relies on two 16.5 cm woofers equipped with aluminum cones. This material, both lightweight and rigid, enables a fast and precise response, essential for deep and articulate bass. Molded polymer baskets and the asymmetrical chamber design help minimize unwanted resonances.

The crossover network uses MartinLogan’s exclusive McCracken-Vojtko topology, the result of years of research in acoustic integration. This sophisticated approach ensures a smooth transition between the different drivers, preserving sonic coherence across the entire audible spectrum.

Sound performance that pushes boundaries

The Motion F20 excels in reproducing music with striking realism. Its soundstage is expansive and precise, allowing each instrument to be pinpointed with remarkable accuracy. Vocals are rendered with a presence and texture that make it feel as though the artists are in the room.

In the high frequencies, the Folded Motion Gen2 tweeter delivers exceptional airiness and finesse. The subtlest details are revealed without ever becoming harsh or fatiguing. Cymbals shimmer naturally, and the harmonics of string instruments are reproduced with astonishing accuracy.

The midrange, crucial for faithfully reproducing most instruments, benefits from the quality of the woven fiberglass driver. The richness of timbres and the precision of attacks give acoustic instruments a palpable presence. Vocals, whether male or female, are rendered with remarkable tonal accuracy and expressiveness.

In the bass, the two aluminum woofers demonstrate their ability to combine depth and control. Bass lines are reproduced with articulation and definition, allowing each note to be distinctly followed. Kick drum impacts have a solid foundation without overshadowing the rest of the spectrum.

The Motion F20’s dynamics are another of its strengths. Capable of reproducing the subtlest nuances, it can also deliver impressive crescendos without audible compression. This ability to accurately follow intensity variations greatly enhances the realism of sound reproduction.

Versatility that adapts to all genres

While designed to satisfy the most demanding audiophiles, the Motion F20 demonstrates remarkable versatility. It excels in reproducing acoustic music, revealing the full richness of audiophile recordings. Jazz enthusiasts will appreciate its ability to recreate the ambiance of clubs, while classical music lovers will be transported by the expansive soundstage it delivers.

The Motion F20 is equally adept with more energetic musical genres. Rock and electronic music benefit from its ability to reproduce high sound levels without distortion while maintaining clarity across different sound layers. Hip-hop and R&B fans will appreciate the depth and definition of the bass.

In a home theater setup, the Motion F20 also showcases its potential. Its ability to faithfully reproduce dialogue, combined with its impressive dynamics, makes it an excellent choice as a front speaker for discerning cinephiles. Paired with other models from the Motion series, it allows for the creation of a coherent and high-performing multichannel system.
