MartinLogan's Motion® LX16 bookshelf speaker has been a smash hit with our customers — and for good reason. This compact speaker creates stunningly natural, transparent sound at a great value. Use a pair to create a high-quality stereo music system, or build a multi-channel home theater around them with a matching subwoofer.

A treat for the ears and the eyes

The LX16 doesn't just sound good — it's a visually striking speaker as well. It sports a furniture-grade, high-gloss finish. And its magnetically attached perforated steel grille lends a stylish look to any room you put it in. Though small in size, the Motion LX16 delivers huge musical enjoyment.

Folded Motion™ tweeter for detailed sound

This member of MartinLogan's award-winning Motion series features advanced speaker technologies like the Folded Motion tweeter.

Dave's expert take

Long-time Crutchfield advisor, writer, and audio guru Dave Bar had this to say about the LX16's unique tweeter design:

"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."
—Dave Bar, long-time Crutchfield audio expert

Bass that keeps pace

The Motion LX16 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.

Product Research


Two-Way Bookshelf Loudspeaker: The MartinLogan Motion LX16 bookshelf loudspeaker employs a two-way speaker design and features MartinLogan's advanced resolution Folded Motion tweeter and a single 5.25" black-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 LX16 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 LX16 bookshelf loudspeaker features a high-excursion 5.25" black-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 5.25" 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 LX16 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 MDF Cabinet: Complementing the Motion LX16 loudspeaker's sonic accuracy is its solidly constructed 3/4" thick MDF cabinet. The cabinet is finished in either high-gloss piano black or black cherrywood, and includes MartinLogan's signature perforated grille. The Motion LX16 speaker's elegant and timeless look 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 (121AM41B, sold separately) can be used to wall mount the speaker. A 3/8"-16 threaded insert on the back of the speaker can also be used with 3rd-party wall-mount brackets; however, 3/8"-16 is not a common size bolt used in wall mount brackets.

Why did you buy this?

Consistently excellent reviews. Looks great. Can't beat the price, AND it's from Crutchfield! [ Craig  Nov 02, 2018 ]
i have been interested for awhile in trying a ribbon like tweeter and the prices on the lx16 are an easy and affordable way to check them out. so i finally went for it and crutchfield always has good timely delivery [ joey  Sep 12, 2018 ]
price [ Kenneth  Jul 29, 2018 ]
When a product from a renowned name like Martin Logan updates an item, often the previous model is a good buy. The Martin Logan Motion LX16 at a $250 price from $400 is, I think, a very good buy. The reviews for the item on your website and the audio press, like What Hi-Fi, seem to be in agreement. And Crutchfield itself has a great rep. [ John Duane  Jul 03, 2018 ]

Product got good reviews [ ryan  Apr 26, 2016 ]
impressive clarity on the highs and mids [ Leonardo  Apr 26, 2016 ]
Love MartinLogan. Love the clarity of their hi-end -- the folded motion tweeter is the best, at least what I can afford. Great mids. Adequate bass. Great for the money. I use these as "fillers" in my stereo system with another set of floor standing B&Ws. And they are great on their own. [ HOYT  Mar 26, 2016 ]
Looking for quality small bookshelf speakers for our living room. Listened to these locally and thought they sounded great. The price seamed to make these a great value. [ Daniel  Feb 22, 2016 ]
read reviews and feel this would work well with turntable and bluesound wireless for home office and eventually for wireless speaker system throughout home [ Beth  Feb 21, 2016 ]
Reviews support good value. Will fit well in the space I have available. [ Tim  Feb 15, 2016 ]
Friends recommendation. [ Chad  Feb 07, 2016 ]
Read numerous reviews on this speaker and it seemed the most competent to complete my 7.1.4 Dolby Atmos setup as my rear surrounds [ Reza  Jan 26, 2016 ]
I have many *FULL* sized Martin Logan speakers and needed something small for the den. ML is a name I know is quality. [ James  Jan 23, 2016 ]
They are an excellent value for the money - same components as the Motion 15 but a slightly different cabinet shape and 40% cheaper. [ Elliott  Jan 03, 2016 ]
read the reviews and the price [ Bruce  Dec 30, 2015 ]
Sound and price [ VINCENT  Dec 10, 2015 ]

4 questions already asked

I think you would be fine - I run my pair of LX16s (and a motion center channel) on a Yamaha RX1800 which has similar specs. Sounds great and runs cool - my amp has a lower ohm setting and I use that. Plenty loud for a 5" bookshelf - tweeter is awesome and bass is very tight. [ Jonathan  Dec 24, 2017 ]
In the real world, 1 ohm will not make any difference. With that said, you may have an option in your receiver's settings to select various speaker loads (ohms) but I wouldn't think twice about it being problematic. Use good speaker wire and interface cabling, polarity matters and good eq matters. A real time analyzer to adjust eq for your listening space matters (you may have one built in your receiver). Enjoy! [ Paul  Dec 22, 2017 ]
I'm pretty sure they will work with your amp But call Crutchfield tech-support to be 100 percent sure [ Bruce  Dec 21, 2017 ]
Can't honestly answer that my receiver is rated to 4 ohms you should ask someone with a similar receiver good luck they are nice speakers [ TIMOTHY  Dec 21, 2017 ]
You'll be fine . If you look at the Martin Logan literature for the lx 16 they are compatible. The lower the ohms on the speakers means they draw more power from the receiver. Good luck [ RAMON  Dec 21, 2017 ]
Sorry but do not have that type of Amp. But with a medium price Solid state they sound fantastic. They don't seem to be power hungry. [ JEFF  Jan 18, 2016 ]
As they have a small woofer, the bass would be a little weak unless, like me, you have a subwoofer. They are efficient but not extremely so. You would not be able play these at a high volume level with a small amp. They are an accurate speaker but seem to be more suited for jazz and classical music. [ Gordon F.  Jan 18, 2016 ]
8 watts of power will produce 101db @ 1 meter (if you believe the 92db sensitivity rating). So, as long as you're in a smaller space they should get plenty loud on 10 watts. If you like to listen really loud though 10 watts may not be enough juice. As for how these handle classic rock.... they're awesome! The folded diaphragm tweeter really does something magical with vocals. I imagine some good Led Zeppelin or Stones recordings will sound great. The only drawback, and this may not be a huge issue for classic rock, is these don't go really low. I would say 60hz is where they start to fall off and I actually cross mine over at 100hz with a sub. Hope this helps! [ Andrew  Jan 17, 2016 ]
Used with NAD C740 35W. Did Bowie dedication on Sunday. I recommend these speakers. [ BRUCE  Jan 17, 2016 ]
I would describe the sound I have obtained from the LX16's as "crisp." Not as clean, airy and precise as my M-L electrostatics (Ascents), but generally pleasant and fit tonally with the Ascents and Cinema center speaker as rear channel speakers in my surround system (the LX16's are not ideal as rear surrounds but I have very limited placement limitations for the rears) . Before putting in the surround sound system, I used them as stereo speakers in my office, 6-8' from listening position, and found them pleasant if a bit limited in bass response. Only negative for me has been that with some source material they are brutally and unpleasantly revealing but that's not the speaker's fault. [ William  Oct 19, 2015 ]
I never got those installed sorry [ GHAZALA  Sep 20, 2015 ]
Guess you could but I would not. [ JEFF  May 08, 2015 ]
Yes - not really designed for use on the side but the folded tweeter sounds so good in the voice range, which is what center channel is mostly used for, that I would definitely use it for the center, space allowing. [ JOHN F  May 06, 2015 ]
The Martin Logan Motion 6 is designed for center - it has 2 mid range speakers and that incredible tweeter that will make voices and the high end sparkle. [ JOHN F  May 06, 2015 ]
It's not really designed for this, but it would probably work very well. most center speakers are oblong with a speaker in the center. This is typical woofer on bottom tweeter on top so putting it on its side moves away from the norm. But, Depending on your space, if you have room below TV to place it there, it will deliver great sound. I haven't tried it with TV, Im just listing to music right now. For stereo it delivers the vocals as good as any speaker I've ever heard. Since center speakers are seemingly designed to deliver voice, this speaker should handle the job perfectly. [ JOHN F  May 06, 2015 ]
I will not recommend as it will not only look odd esthetically and the placement of the tweeter will not give an optimal sound quality expected from a center channel. These speakers are not optimized to work as center channel. However, technically you can connect it to a center channel output. [ Amitabh  May 04, 2015 ]
Hello Greg. I don't know very much about setting up surround sound type systems, however I can say that I am very pleased with the high and mid range clarity produced by the LX16. Lots of detail comes out of these speakers. They are awesome. Also, I don't think it would matter much if the speaker was upright or sideways. My guess is that it would still sound pretty much the same, at least to my ears. Good luck. [ brian  May 04, 2015 ]
you can, but the dispersion may not be correct from the tweeter... it would be 90 degrees from normal [ James  May 04, 2015 ]
Yes. I have 3 of these handling F C L duty w/ the center channel on its side. Lobing can occur but this is only a concern if you are sitting pretty far off center. [ Andrew  May 04, 2015 ]
The only problem I see would be the ribbon tweeter not being positioned the way Martin Logan designed. The size of the speaker is consistent with other center channel designs so I dont think fit would be a problem. I would try it but I picked up a Motion CC2 center as an open box buy and am real happy with the sound. The Motion center does have two woofers with a ribbon tweeter in the middle. Not sure how one woofer would affect the sound. I wouldn't hesitate to try it as a center if I didn't already have the Motion center channel. I kind of had to disassemble the top of my TV stand to place my center channel speaker in the right place so I can not change them out very easily or I would offer to try it and get back with you. [ PEDRO  May 04, 2015 ]
I guess, but its not designed that way? They are great speakers though. [ stephanie  May 04, 2015 ]
