Our take on the MartinLogan Motion® 2i

I'm a minimalist when it comes to my home office — I need an uncluttered space in which to work. But I also love listening to music, and want clear, natural sound without losing desk or floor space. MartinLogan's Motion® 2i is a perfect speaker for that kind of job. 

Excellent fidelity from a compact design

I'm a minimalist when it comes to my home office — I need an uncluttered space in which to work. But I also love listening to music, and want clear, natural sound without losing desk or floor space. MartinLogan's Motion® 2i is a perfect speaker for that kind of job. 

Grab a pair of these wall-mountable speakers for a stereo music system, or as many as you need for a MartinLogan surround sound system.

MartinLogan Motion® 2i bookshelf speaker

MartinLogan's Motion 2i bookshelf speaker uses a Folded Motion tweeter for fast, articulate highs.

An acclaimed tweeter delivers smooth, sweet highs

One of the reasons the Motion 2i sounds so good is its Folded Motion™ tweeter. This unique, accordion-style design is quick, accurate, and very smooth. You'll enjoy clear, natural sound throughout its frequency range. 

Since this speaker is relatively small, you may want to pair it with a powered subwoofer for deeper bass performance.

Versatile design adapts to your room

MartinLogan recommends mounting the Motion 2i "right side up" at ear level, but upside down if it's above ear level. This lets it disperse sound down towards you for optimal sonic performance. It even includes the wall-mount bracket, so you can attach it to your wall for awesome sound that's out of the way.

Building a MartinLogan surround sound system? I recommend using a MartinLogan Motion center channel speaker for voice-matched sound.

Great speakers, modern design

Crutchfield Customer Review (What's this?)

Wow, these are really nice! I have them paired with a Dayton 8" sub in a 2.1 audio system powered by a Yamaha A-S801 and they're really sweet. I've got them wall mounted upside down, angled down just like the instructions say and they work great. The tweeter and mids a just very, very sweet sounding and not harsh at all. The cabinet itself is an odd design; it's curved, so if you mount it at ear level it's supposed to be mounted right side up. But if you mount it above ear level, Martin Login recommends you mount it upside down, angled slightly (20 degrees) downwards. Mine are mounted upside down, and they sound really great in a 25x15 room. I'm not normally blasting these, I'm usually listening at normal levels, but I've cranked them a few times and they sound great at louder levels - no distortion. There's one thing I really like on the front of the cabinets - the custom, curved, metal grill. It has special stamping for the folded tweeter, it's curved to match the rest of the cabinet, and it's magnetic, so it easily snaps on the front of the cabinet. The one (and only) thing I don't like are the posts on the back. To insert the speaker wire you have to snake the wire in through a recessed channel in the rear of the cabinet. It's kind of a pain to get the wire in. But it's a small thing and not a deal breaker. These are very high quality speakers that sound very, very good when paired with a sub. I wouldn't run these without a sub. Recommended - very nice!

Pros: Sound fantastic, high quality cabinets and components

Cons: "Modern" cabinet design might not be for everyone, installing speaker wire into channel not easy

Product Research


Folded Motion Tweeter: MartinLogan's Folded Motion Tweeter helps give the 2i 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 0.94" x 1" 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 2i 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 2i loudspeaker features a precision Vojtko crossover (3800Hz) 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 2i 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 2i 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. The grille is magnetic and detachable.

Spring-Post Connectors: The MartinLogan 2i 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).

Versatile Mounting Options: The MartinLogan 2i 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 2i 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 2i 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 2i 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.
