A mini-monitor for music lovers
The Motion 15 uses a 5-1/4" aluminum cone mid/woofer and MartinLogan's innovative Folded Motion tweeter.
A mini-monitor for music lovers
The operative word for MartinLogan's Motion 15 is "beauty." This mini-monitor has it in spades, from its furniture-grade fit and finish to its stunningly natural sound. This member of MartinLogan's award-winning Motion® series features advanced speaker technologies like the Folded Motion™ tweeter. Though small in size, the Motion 15 delivers huge musical enjoyment.
Folded Motion tweeter for detailed sound
MartinLogan's innovative Folded Motion 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.
Bass that keeps pace
The Motion 15 uses a 5-1/4" aluminum cone woofer to supply fast, clean midrange and lower-mid frequencies that blend in seamlessly with the Folded Motion tweeter. A low-turbulence rear-firing port extends bass performance, but keeps it tight and tuneful.
Deceptively good sound
When MartinLogan visited Crutchfield for a day of training, they had a mix of their electrostatic and dynamic models lined up in the front of the room. They started off our session with a few minutes of an atmospheric live track. The sound was strikingly open and immediate — we thought we were listening to one of ML's electrostatic panels. Imagine our surprise when it turned out to be the little Motion 15s. Sometimes it's fun to be fooled.

MartinLogan Motion® 15 reviews
I've temporarily downsized from a large house to a small apartment, requiring a downsizing of my gear. Because it is a temporary situation I didn't want to spend too much money, and I was wary of the compromise in sound quality I thought would result. Well these little babies, driven by a NAD 3045, sound wonderful. The high end is alive but smooth, which is a priority for me. The midrange is quite natural, not nasal or honky, and there is enough bass to feel like you aren't eating just lettuce. Also, Crutchfield took care of a packaging issue very nicely. I'm happy.
Pros: Nicely balanced and satisfying sound. Reasonably priced. Great build quality.
Cons: I don't know how they would perform in a large room.

Excellent service. They will be my go to electronics store from now on. An extreme pleasure to deal with and glad there are companies out that still care about their customers.
Pros: Amazing sound

Full, rich sound in a small package. Perfect for my home office. Stylish, but understated design allow them to melt into the decor, so all you notice is exquisite sound. Pair nicely with the Yamaha R-N303 receiver/ amp.

I purchased these speakers because I thought I had a defective speaker. ADS 570's (have replaced tweeters twice) . I ordered https://www.crutchfield.com/p_839MO2GB/MartinLogan-Motion-2.html?tp=186. I did not like them at all. I sent them back next day . I said the heck with it and purchased the martin Logan motion 15. I then double checked and I had a faulty amplifier channel. After listening to these speakers I decided to keep them anyway because they sounded awesome. I listen to a lot of 60's and 70 music and its like hearing a lot of this stuff for the first time. The clarity etc. I would love to hear the next level up,but I am happy with this speakers .

Love these speakers. For bookshelves they sound amazing and seem to have very good build quality. Vocals sound terrific.

Purchased for listening to music only...pure listening pleasure. The low is is not strong (as expected) which is why I also purchased the ML Dynamo 700W. I am pushing 80W RMS thru a pure direct networked amp.

After 15 years I decided to upgrade my Hi-fi setup to incorporate the latest technology. My plan was to upgrade my 5.1 system to an 11.1 Atmos system (with direct radiator speakers). My original Boston Acoustic speakers are reference quality so I planned to move them to height speakers. This left me to decide what speakers to use as my "floor" 7.1 surround. My room presents difficult acoustic and space issues. The surround speakers needed to be mounted high on the wall focused almost 60º down. After checking into several brands and reviewing my space, I decided that the Motion 15 speakers were the best all-around choice . The matching front, center and surround speakers provide superior brightness, clarity, presence and bass. They rival larger speakers that go for twice the $.
Pros: Excellent sound quality for the relative small size.
Cons: Difficult to find speaker mounts that allow downward angle of 60º.

I have been very happy with these speakers. I use them as rear and side speakers in a 7.1 channel configuration (planning to add more). The sound is very crisp and their red hue looks great in our living room as well.
Pros: Quality of sound and physical appearance.

I drive the speakers with an 25 plus year old Yamaha integrated amp, 25 watts/channel and CD player as only source. They sound very clean, about 8 feet off the floor, 3 feet apart, on a shelf, projecting to the center of an approximately 15 x20 foot room with cathedral ceiling. I hear the full instrumentation of a symphony and can hear overtones and harmonics well with violin and piano duo in a good recording.
Pros: I feel they are an excellent value for the price.
Cons: None for my use.

Ear-opening! In the interest of full disclosure, I'm powering these through a Sonos Connnect:Amp, with iTunes media. I leave the "Loudness" feature turned off to not let any digital trickery get in the way. The difference between my previous speakers--which I thought were rather good, and certainly get rave reviews--and the Motion 15s is astonishing. To be fair, the Motion 15s are more expensive more, but not much larger, and yet the bass is many times bigger. They do astonishing things with acoustic music and smaller-scale rock. I'm not fussy about sitting in the perfect listening position all the time, but still they fill the room and really begin to open up with the Connect:Amp approaching 50%. Depending on the recording, of course, the bass is incredible. There is plenty of thump without being ridiculous, and the mids are still intelligible. Only dirty, low-fi music like Iggy Pop gets garbled, but I think that's the intent of the recording. One minor quibble is that I'm still getting used to the clarity of the folded motion tweeter. It's perhaps a placebo effect because I know it's a very efficient design, but on some songs, the tweeter comes on a bit strong. For example, the tambourine or whatever it is on "I Know" by The Beta Band hits hard. Dialing down the treble in the simplistic Sonos controls takes the edge off. As an aside, I do wish the ML 35XT came in white, as I have a hunch they would sound even "fuller" at lower volumes. If they offer that color I'll upgrade.
Pros: Small, elegant, unique
Cons: Some recordings, but not all, feel very bright, possibly because to the tweeter design.

I decided that I needed something new to fill in the "empty spot" in my home theater and 2.1 stereo listening experience. Up until now, I have been a lifelong Bose believer. My very first set of "real" speakers was a set of 301s that I bought in 1994 with paper route earnings. Every speaker in my house up to this point has been Bose, right down to my headphones that I am listening to as I write this review. I am clearly a lifelong Bose supporter, so I'm not here to bash them. Now don't think for one minute that I haven't read the scathing critiques of Bose over the years (no highs, no lows...) . Of course I have. But I LOVE my 901s and their wide open, extremely spatial imaging. And after listening to music through the brand for over 25 years, it's what music SHOULD sound like, right? Enter the Martin Logan Motion 15s. Martin Logan was wonderful enough to grace my ears with these speakers, and I'm not sure that I will ever understand music the same way again. I now see why SOME people have always had a different take on how music should sound. While it most certainly varies from recording to recording based on the song in question, there is an unmistakable presence in the Martin Logans that my Bose never had. Not EVERY song, but most songs. It almost makes me shudder to think what I would feel about ML if I had splurged the extra $400 and gone with the 35XTs. And I'm not all that certain that in the next few weeks that I won't exercise my return option & get them.
Pros: Incredible sound in a very tight footprint with beauty and elegance to match.
Cons: Maybe I should have gone with the next model up. If these sound so awesome, maybe the 35XTs will blow my mind....?

I had never heard of the Martin Logan brand of speakers until they were recommended to me by Buzz at Crutchfield.com. I needed speakers with a small footprint for a white living bookshelf, but I also want a full, rich orchestral sound to compliment my Harman Kardon 3490 stereo receiver. The Martin Logan Motion 15 speakers were perfect. The sound is stunning - I am hearing clarity of orchestral instruments that is just amazing. The look is very elegant, and one can tell these speakers were designed and made with care. I also appreciate the ability to have a 5-year warranty built into a product as long as it is registered with the company. That is so rare these days unless one purchases a separate extended warranty. I like the confidence this shows in their products. I highly recommend the Martin Logan Motion 15 speakers if you want high-quality sound with a smaller footprint. As usual, the service at Crutchfield.com is 5-star and I will most definitely be back when making my next purchase. I only wish I had heard of the Martin Logan brand earlier - great craftsmanship and an even better sound.
Pros: Excellent sound; relatively small footprint; gorgeous and elegant color and design; easily connected; the initial burn-in period for the speakers is no problem since they sound wonderful right out of the box and are only getting better as the days go on;
Cons: There are no "cons" to these speakers that I can see unless being a tad heavy is a "con". I look at the slight heaviness, however, as a plus since it appears the weight is due to the speakers being well-made, durable, and of very high-quality workmanship.

I hear things on my music collection that I have never heard before. I could not be happier with my purchase. Hunter recommended these speakers and I could not be more satisfied.
Pros: Positive remarks all the way around to the looks of the speakers to the sound of them.

2-Way Bookshelf Loudspeaker: The MartinLogan Motion 15 bookshelf loudspeaker employs a 2-way speaker design and features MartinLogan's advanced resolution Folded Motion tweeter and a single 5.5" aluminum cone midbass woofer. Pairing these two drivers together creates a dynamic full-range sound with an expansive soundstage.
- Folded Motion Tweeter: MartinLogan's Folded Motion tweeter helps give the Motion 15 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.
- Aluminum Cone Woofer w/ Bass Port: The MartinLogan Motion 15 bookshelf loudspeaker features a high-excursion 5.5" aluminum cone woofer with a cast basket housed in a non-resonant asymmetrical chamber with a rear-firing bass port. The aluminum cone woofer uses a rigid structured dust cap to reduce cone break-up and distortion. Pairing the 5.5" woofer with a rear-firing bass port provides higher output and audibly richer, deeper bass performance.
Precision Crossover: To seamlessly blend the audio output from the high frequency driver (tweeter) and the midbass driver (woofer), the Motion 15 loudspeaker features a precision 2,700Hz crossover utilizing custom air core coil and low DCR steel laminate inductors, polyester film capacitors in series, and low DF electrolytic capacitors in parallel.
High-Gloss Cabinet: Complementing the Motion 15 loudspeaker's sonic accuracy is its elegant, yet understated styling. A high-gloss, piano black, white or black cherrywood finish, along with MartinLogan's signature perforated grille, give the Motion 15 speaker an elegant and timeless look that will blend into almost any decor. The speaker cabinet also features rounded edges and a gently tapered top.
Binding Posts: MartinLogan's proprietary tool-less binding posts simplify cable connection and management. The binding posts will accept bare wire (16- to 10-gauge), pin-connectors, spade-connectors, and banana plugs (single only).
Break-in Period: Allow approximately 72 hours of break-in at 90 dB (moderate listening levels) before any critical listening.
Mounting Options: The bookshelf loudspeaker comes with 4 rubber self-adhesive feet to help secure them in place on a flat-surface, prevent slippage, and reduce vibration. The optional PinPoint heavy duty side-grip wall-mounting bracket (121AM40B, sold separately) can be used to wall mount the speakers.
