The MartinLogan Motion B10 can star in your stereo setup or shine as a front or surround speaker in a Motion home theater system. This stand-mount speaker delivers accurate, detailed sound that matches others in the Motion lineup, based around carefully chosen drivers, precise crossovers, and an acoustically optimized cabinet. And it comes in three gorgeous finishes, so you can choose one that suits your home decor.

Impressive Motion® tweeter

MartinLogan's acclaimed Folded Motion tweeter uses a pleated diaphragm that works similarly to an accordion by "squeezing" air to create sound. The B10's upgraded Gen2 Obsidian version of this tweeter uses larger magnets for greater detail and accuracy. The new design places it inside a custom Folded Motion waveguide that enhances dispersion of high-frequency sound throughout your listening area. 

Because it requires almost 90% less excursion than the typical 1" dome tweeter, response time is drastically reduced along with distortion. The diaphragm's increased surface area also provides wide, yet controlled sound dispersion to create a realistic and highly accurate soundstage. Music sounds detailed, but smooth and effortless, without a trace of harshness.

Accurate midrange and solid bass

The B10 boasts a 5-1/2" woven fiberglass cone woofer that delivers accurate mid/bass performance. The cabinet's rear-firing port helps deliver solid low end that enhances your experience with music, movies, and gaming.

Matching stands are a must-have for hi-fi performance

Placing the B10s on a solid set of speaker stands can minimize sound-muddying vibrations and allow them to perform as designed. Specifically, we recommend using the matching MartinLogan STAND25 so the speakers will fit on the top plates properly and the tweeters will be placed at approximately the same height as your ears, for the best possible sound.

Placement tip: because the B10s are rear-ported, they'll sound better if you can position them with a little extra space between them and the wall.

Unique crossover network

MartinLogan's proprietary Vojtko™ crossovers are named after MartinLogan's chief audio technologist, Joe Vojtko. The latest Motion speakers feature upgraded McCracken-Vojtko crossovers, so named for the influence of the company's other well-known Joe — senior loudspeaker designer Joe McCracken.

No matter what they're called, the aim is always the same: each speaker's drivers are carefully selected or designed to operate within an intentional frequency range and specific performance parameters. That allows the crossover networks — built from high-quality capacitors and resistors — to be clean and uncomplicated, for purer sound.

Features

Thin-Film Technology & Controlled Dispersion: By using advanced Thin-film Technology and Controlled Dispersion, the MartinLogan Motion B10 bookshelf loudspeaker delivers excellent high frequency response from its Gen2 Obsidian Folded Motion Tweeter (FMT) and Folded Motion Waveguide. The Gen2 Obsidian FMT uses a folded thin-film diaphragm to compress and expand air, creating a large surface area that delivers fast, accurate, and detailed high frequency reproduction. The integrated Folded Motion Wave Guide creates Controlled Dispersion to minimizes sound degrading early reflections by controlling the spread of sound from the tweeter into the room, enhancing your listening experience with greater clarity, and expanded placement options in the room.

  • Gen2 Obsidian Folded Motion Tweeter (FMT): The Motion B10 features MartinLogan's latest and greatest Thin-Film Technology, the Gen2 Obsidian Folded Motion Tweeter (FMT) - measuring 1" x 1.4". With an upgraded motor structure, the latest Gen2 Obsidian FMT provides higher output and lower distortion than ever before. The Gen2 Obsidian FMT's internal improvements elevate performance to new heights for a clean, detailed, and accurate high frequency response.
  • Folded Motion Waveguide: The Folded Motion Waveguide profile was meticulously chosen to harmoniously align the tweeter's output with the dispersion of the midrange/bass driver, resulting in enhanced output. The waveguide guarantees consistent sound quality regardless of the listener's position and minimizes unwanted room reflection for Controlled Dispersion of 90-degrees (h) x 90-degrees (v). 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.

5.5" Woven-Fiberglass Cone Woofer: In addition to the 1" x 1.4" Gen2 Obsidian Folded Motion Tweeter & Waveguide, the MartinLogan Motion B10 bookshelf loudspeaker houses a 5.5" Woven-Fiberglass midrange/bass driver with a rubber surround and cast polymer basket. The lightweight and strong Woven-Fiberglass cone driver is perfectly suited for keeping pace with the Gen2 Obsidian FMT, providing crystal clear dialog and vocals, as well as lifelike instrumentals.

McCracken-Vojtko Crossover: Carefully designed using proprietary measurement and simulation software, plus tuned using double-blind listening, the McCracken-Vojtko 2-way crossover perfectly melds the 1" x 1.4" Gen2 Obsidian Folded Motion Tweeter and 5.5" Woven-Fiberglass midrange/bass driver together for a cohesive and beautiful sound.

Bass Reflex MDF Cabinet: The Motion B10 bookshelf loudspeaker employs a solid built cabinet design to eliminate fidelity robbing vibrations. The speaker cabinet is constructed from MDF (medium density fiberboard) with an extra-thick front baffle and additional internal bracing to further reduce cabinet resonance. On the back of the cabinet is a rear-firing port which helps the speaker be more efficient and have better bass performance. The cabinet is available in three finishes - Satin White, Walnut Veneer, or Gloss Black.

Binding Posts: The MartinLogan Motion B10 bookshelf loudspeaker is outfitted with a set of high-quality binding post terminals that will accept bare wire (up to 10AWG), pin-connectors, spade-lugs, and banana connectors (single only).

Mounting & Placement Options: The Motion B10 loudspeaker can be positioned on a bookshelf, tabletop, speaker stand (sold separately - see Accessories Tab), or other flat surface. MartinLogan's STAND25 (sold separately) is the perfect matching speaker stand for the Motion B10 bookshelf speaker, providing an optimized fit and maximum stability. Four feet are included to isolate the speaker from the mounting surface and to protect the mounting surface and speaker from scratches. The feet add approximately 0.25" to the overall height of the speaker.

  • Although the speaker is designed to deliver a superb sonic performance when placed close to a wall, you may notice improved imaging and detail if you are able to place the speaker 2' or more' from the rear wall and 2' or more from the side walls.
  • To achieve the best stereo imaging, a pair of speakers should form an equilateral triangle between each other and the main seated listening position.
  • To enhanced the stereo image even more, you should angle (or "toe-in") a pair of speakers toward the primary listening position.
  • Try to position the speaker so the tweeter is at ear-level in regards to your main listening position when seated.

Note: The Motion B10 does not include any brackets, keyhole-slots, or threaded inserts to wall-mount the speaker.

Motion Series: MartinLogan's Motion Series is inspired by the performance of their top-of-the-line electrostatic speakers and is perfect for music or home cinema lovers. Pairing high-performance Woven Fiberglass midrange/bass drivers with the latest Gen2 Folded Motion Tweeter technology. With a bold new look and a suite of new audio upgrades, the Motion series is ready to impress in your home. Through a rigorous development process involving anechoic chamber measurements, blind listening tests, and in room measurements MartinLogan crafted a more refined sound for the Motion Series that is a whole new level of quality and excellence. The Motion Series consists of two floorstanding loudspeakers (Motion F10/F20), a bookshelf loudspeaker (Motion B10), center-channel speaker (Motion C10), and a Surround loudspeaker (Motion MP10).

Optional Powered Subwoofer: Add on an optional MartinLogan powered subwoofer (sold separately - see Accessories Tab) for bigger and deeper bass response when listening to your movie and music soundtracks.
