The MartinLogan Motion B10 is a bookshelf speaker that combines advanced technology with refined design. Compact, it features a next-generation folded ribbon tweeter and a woven fiberglass mid/bass driver. Its glossy black finish allows it to blend seamlessly into modern interiors while delivering precise and immersive sound reproduction.
A refined design for all interiors
The Motion B10 stands out with its modern and sleek aesthetic. Its straight lines and sharp angles give it a decidedly contemporary look. The glossy black finish adds a touch of sophistication and subtly reflects light, creating a striking visual effect. The compact dimensions of the speaker (31.8 cm in height, 17.8 cm in width, and 24.8 cm in depth) make it easy to integrate into various spaces, whether on a shelf, desk, or low cabinet.
The removable magnetic grille, covered with acoustically transparent fabric, protects the drivers while preserving sound quality. When removed, it reveals the folded ribbon tweeter and mid/bass driver, showcasing the cutting-edge technology inside this speaker.
The heart of the Motion B10 lies in its Folded Motion Gen2 tweeter, an evolution of MartinLogan’s iconic technology. This folded ribbon tweeter uses an ultra-lightweight accordion-folded diaphragm, offering an impressive diaphragm surface area of 59.4 cm². This design enables exceptional transient response and minimal distortion, resulting in highs of remarkable clarity and precision.
The Folded Motion waveguide, the result of extensive research among nearly 50 design options, optimizes sound dispersion. It ensures tonal consistency over a wide listening angle and minimizes unwanted reflections, creating a broad and precise soundstage.
Woven fiberglass mid/bass for controlled bass
The 14 cm driver dedicated to mid and low frequencies uses a woven fiberglass cone. This material combines lightness and rigidity, enabling fast and precise movements. The result is a natural and detailed reproduction of voices and instruments, with excellent articulation of low frequencies.
The high-resilience polymer basket contributes to the mechanical stability of the assembly, reducing unwanted resonances and ensuring pure, uncolored sound reproduction.
Sound performance
Despite its compact size, the Motion B10 delivers impressive sound performance. Its frequency response of 56 Hz to 25 kHz (±3 dB) covers a wide portion of the audible spectrum, ensuring faithful reproduction of most musical sources. The high sensitivity of 92 dB allows for comfortable sound levels, even with moderately powered amplifiers.
The 90° sound dispersion, both horizontally and vertically, ensures an extended listening area. This feature, combined with the precise stereo imaging offered by the Folded Motion tweeter, creates an immersive and realistic soundstage.
Remarkable installation versatility
The Motion B10 adapts to various listening configurations. Its compact size allows it to be placed on a shelf, desk, or low cabinet. For those who prefer a stand-mounted setup, MartinLogan offers the optional STAND25 stand, which screws directly under the speaker for optimal stability.
The speaker is also compatible with multi-channel home theater systems. Its tonal neutrality and precision make it an excellent choice for front or surround channels in a high-end home theater setup.
MartinLogan’s audiophile heritage
The Motion B10 benefits from decades of MartinLogan’s acoustic expertise. Known for its high-end electrostatic speakers, the brand has successfully translated its know-how into this compact speaker. The McCracken-Vojtko crossover, the result of extensive research, ensures a smooth transition between the tweeter and the mid/bass driver.
The custom 5-way binding posts accommodate various types of connectors (banana plugs, spades, bare wire) and ensure a stable, high-quality connection with the amplifier.

Frequently Asked Questions
What is the main difference between the Motion B10 and the previous generation?
+
The Motion B10 features the Folded Motion Gen2 tweeter, an evolution of the previous model. This new generation offers higher efficiency and lower distortion thanks to an improved motor structure. Additionally, the waveguide has been redesigned to optimize sound dispersion and improve coherence with the mid/bass driver.
Can the Motion B10 be used in a home theater system?
+
Absolutely. The Motion B10 is perfectly suited for home theater use, whether as a front, center, or surround speaker. Its tonal neutrality and precision make it an excellent choice for faithfully reproducing movie soundtracks and surround effects.
How should these speakers be positioned for the best performance?
+
For optimal stereo listening, place the speakers equidistant from the listening position, forming an equilateral triangle. Keep them at least 30 cm away from walls to avoid excessive bass emphasis. Experiment with the toe-in angle (inward orientation) to refine stereo imaging according to your preferences and your room’s acoustics.
