A versatile performer from MartinLogan

MartinLogan's Motion series speakers are known for sound that's realistic and immediate without being overbearing or harsh. The elegant-looking Motion 2 bookshelf speaker is a great way to enjoy signature MartinLogan performance in a wide variety of rooms and systems where space is tight. This versatile speaker is the smallest member of the Motion series, and it fits easily on a shelf or A/V cabinet. Or you can take advantage of its included wall bracket and mount it beside a flat-panel TV. Use a pair for stereo music or for your front or rear channels in a surround sound home theater system.

Folded Motion™ tweeter for detailed sound

MartinLogan Motion 2 tweeter detail

The Motion 2 uses MartinLogan's acclaimed Folded Motion tweeter for smooth, effortless highs.

The distinctive sound of the Motion series starts with MartinLogan's Folded Motion tweeter. Rather than a dome or cone driver, this tweeter uses a pleated diaphragm that works like an accordion by "squeezing" air to create sound. It requires about 90% less excursion than a typical 1" dome tweeter, resulting in quicker response time and much lower distortion. The tweeter's controlled sound dispersion creates a focused soundstage with a real sense of presence. Music sounds amazingly detailed, but smooth and effortless, without a trace of harshness.

A stylish, curved cabinet

The tweeter is coupled here with a low-mass 3-1/2" poly cone woofer that supplies accurate mids and midbass. Both drivers are mounted in an eye-catching curved cabinet that's finished in classic high-gloss piano black. The Motion 2's subtle, modern lines complement just about any décor. If you're mounting this speaker high up on your wall, you can invert it to aim the high frequencies downward toward your listening position.

Be sure you get enough bass

This speaker shines when it comes to accurate mids and highs, but for any kind of bass we strongly recommend a powered subwoofer, like one of MartinLogan's excellent models.

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

Features

Folded Motion Tweeter: MartinLogan's Folded Motion Tweeter helps give the Motion 2 bookshelf loudspeaker its natural, realistic high frequency sound. Lightning fast transient response, combined with a large surface area (8x that of a typical 1" dome tweeter) creates clear, dynamic, and precise sound. The 1" x 1.4" Folded Motion Tweeter works by moving air (which creates sound) perpendicular to the folded ridges of the diaphragm, similar to how an accordion works. This extremely low mass diaphragm "squeezes" air and requires almost 90% less excursion than the typical 1" dome tweeter, which drastically minimizes distortion while providing a lightning fast response time. The increased surface area also provides a wide, yet controlled sound dispersion (80°x80°) to create a realistic and carefully etched sound stage.

3.5" Poly Cone Woofer: The MartinLogan Motion 2 loudspeaker features a 3.5" poly cone woofer with a stamped steel basket housed in a non-resonant asymmetrical chamber. The poly cone woofer uses a rigid structured dust cap to reduce cone break-up and distortion. This 3.5" cone woofer provides rich, detailed midbass.

Precision Vojtko Crossover: To seamlessly blend the audio output from the high frequency driver (tweeter) and the midbass driver (woofer), the Motion 2 loudspeaker features a precision Vojtko crossover (2800Hz) utilizing custom air core coil and low DCR steel laminate inductors, polyester film capacitors in series, and low DF electrolytic capacitors in parallel.

Curved High-Gloss Black Sealed Cabinet: Complementing the Motion 2 loudspeaker's sonic accuracy is its elegant, yet understated styling. A high-gloss, piano black finish and subtle curves, along with MartinLogan's signature perforated grille, give the Motion 2 speaker an elegant and timeless look that will blend into almost any decor. The cabinet is an acoustic suspension design (sealed) for tighter, accurate midbass.

Spring-Post Connectors: The MartinLogan Motion 2 speaker features two spring-post connectors to attach your speaker wire. The spring-posts will accept bare wire (16- to 10-gauge), pin-connectors, and banana plugs (single only). The rubber caps on the spring-post connectors must be removed to use banana plugs.

Versatile Mounting Options: The MartinLogan Motion 2 bookshelf loudspeaker can simply be placed on a table-top, stand, shelf, or other flat surface. Four self-adhesive rubber feet are included for safe and secure placement. Using the included keyhole-slot bracket, you can wall-mount the speaker at two different angles. This means you can point sound directly toward the desired listening area for high or low wall mounting applications. In addition the Motion 2 is fitted with a 1/4"-20 threaded insert which allows you to hang the speaker on the wall using optional articulating wall-mount brackets (sold separately).

  • If the Motion 2 is being mounted at approximately ear-level, the speaker should be oriented with the tweeter at the top. This will disperse sound directly towards the desired listening area.
  • If the Motion 2 is be mounted above ear-level, the speaker should be oriented with the tweeter at the bottom. This will disperse the sound down at a 20° angle towards the listening area.
Note: The MartinLogan logo badge on the Motion 2's grille can be re-position based on how you have the speaker mounted.
