Take your surround sound higher with Dolby Atmos and MartinLogan

If you're using MartinLogan speakers in your home theater, you already know just how good they sound. Now MartinLogan offers a way to add even greater richness, clarity, and depth to your surround sound system with their Motion AFX Dolby Atmos enabled speakers. These add-on surround speakers feature technologies designed to work with your MartinLogan speakers and Dolby Atmos soundtracks to re-create an immersive, high-impact listening experience.

Not familiar with Dolby Atmos? It's the latest surround sound technology from the movie- and theater-sound experts at Dolby Laboratories. It adds a height dimension to your home theater, for enhanced immersion and spatial effects. From the soft patter of rain to the roar of a jet flying overhead, you'll enjoy dynamic surround sound that elevates your entire home theater.

Bounce sound off the ceiling for enhanced surround effects

How do these speakers work? Each features a 5-1/4" poly cone woofer and an aluminum dome tweeter located on top of the speaker. These drivers are angled to reflect sound off of your ceiling and back down to your listening positions. The Motion AFX speakers are designed sit on top of your existing floor-standing or bookshelf speakers. Use a pair with your main left and right fronts, or add another pair to the rear surrounds for an even more enveloping experience.

The AFXs are voiced-matched to work in perfect harmony with MartinLogan's Motion series speakers. They can also be used with MartinLogan's electrostatic speakers if placed within three feet of the electrostats, and positioned to allow them to radiate sound directly towards the ceiling. 

Build a complete MartinLogan Dolby Atmos system

Team a pair or two of Motion AFX surrounds with other MartinLogan Motion series 15, 20, 35XT, 40, and 60XT speakers to create a high-impact Atmos home theater system.

Product Research


Dolby Atmos Enabled Speakers: MartinLogan Motion AFX speakers are designed to reflect sound off of the ceiling in a Dolby Atmos entertainment system. The Motion AFX Dolby Atmos enabled speakers create a height layer of sound above the listener that better connects viewers with the richness, detail and clarity of the on screen experience.

Note: In order to enjoy Dolby Atmos, you will also need a Dolby Atmos compatible receiver, a 5.1ch or 7.1ch speaker setup, and Blu-ray Disc content encoded for Dolby Atmos; in addition to the Motion AFX speakers.

Dolby Atmos Surround Sound Technology: Dolby Atmos delivers captivating sound that places and moves audio anywhere in the room, including overhead, to bring entertainment alive all around the audience. Whether you are listening to music, movies, television shows, or playing your favorite video games, Dolby Atmos delivers the full impact of the entertainment experience.

Mounting Options: The MartinLogan Motion AFX is designed to sit on top of floorstanding and bookshelf speakers in MartinLogan's Motion series. These models include the Motion 15, 20, 35XT, 40 and 60XT (all sold separately). The AFX will also work with other brands of speakers with a flat-surface top. Please consider the following when installing your Motion AFX speakers.

  • Add Motion AFX speakers in pairs (2 or 4 speakers). If using only two Motion AFX speakers, they must be placed with your front left/right speakers. If using 4, they must be placed with your front left/right and back surround left/right or side surround left/right if you do not have back speakers.
  • Make sure the Motion AFX speaker's output is not blocked and points at the ceiling and towards the primary listening position.
  • Place the Motion AFX on top of your front or rear surround speakers or within 3' of these speakers, and slightly above ear height.
  • Avoid placing the Motion AFX speakers higher than one-half the height of your ceiling.
  • For optimal performance, use the Motion AFX speakers in a room with a flat ceiling and with a ceiling height of 14' or less, ideally with a height between 7.5' and 12'.
  • To avoid unwanted proximity effects, place the Motion AFX speakers at minimum of 3' from the listening position, or ideally 5' or more.
Note: The Motion AFX is not recommended for use on top of MartinLogan's electrostatic speakers, as the electrostatic panels will block the radiation of the AFX's sound towards the ceiling. The Motion AFX can be used with electrostatic speaker if placed within 3' of the electrostats and in such a way that their sound is capable of radiating directly towards the ceiling.

Two-Way Driver System: Each Motion AFX speaker features a 0.75" aluminum dome tweeter and 5.25" polypropylene cone bass/midrange driver with stamped steel basket inside an acoustic suspension (sealed) cabinet.

Note: When manually setting up bass management in your AV receiver, please set the height channels to small or 120 Hz if small is not available. The Motion AFX is not designed for full-range operation.

Angled Cabinet Design: The shape of the Motion AFX cabinet is specifically designed to angle the drivers towards the ceiling in order to accurately deliver a Dolby Atmos sound experience above the listeners. The cabinet feature a beautiful high-gloss black finish.

Binding Post Speaker Terminals: Each Motion AFX speaker is fitted with a set of binding post speaker terminals that will accept bare wire (up to 12AWG), pin-connectors, spade-connectors, and banana plugs. These speaker terminals will need to connect to your AV receiver's dedicated height channels for Dolby Atmos.

Break-in Period: Allow approximately 72 hours of break-in at 90 dB (moderate listening levels) before any critical listening.

Customer Q&A

Crutchfield asked  
Why did you buy this?

Magazine review. [ Garnot  May 08, 2017 ]
Excellent product for Dolby Atmos [ Benjamin  Feb 03, 2016 ]
Because I already have MartinLogan floor speakers. These will look the same, and fit well on top of them, the way they are supposed to be used. [ Michael  Dec 28, 2015 ]

2 questions already asked

I have not seen any information indicating any other color outside of gloss black. I must admit however the black color looks very nice and oh yeah they sound great too. [ JESSE B  Apr 23, 2018 ]
They would work perfectly with the LX16s. The shape is designed the same as all ML speakers. I use them on top of my Revel P3 F206s. [ Jeff  Nov 25, 2017 ]
I have the afx on my Motion 40 front channels and I bought a second set of these and some LX16 to use as my surround setup for a 5.1.4 system. The motion AFX were slightly wider and the angle was definitely a little weird looking on the lx16. It projected forward a little. My wife was so opposed I ended up getting the motion15 speakers to use with these instead. They fit perfect on the motion 15 and look much better. I ended up keeping the lx16 and using them to setup 7.1.4 so was a win win but if only going with the lx 16 it will look a little off. That said they worked great and if you have those speakers and are looking for Atmos I don't know of other options that would potentially look any better. [ Nicholas  Nov 25, 2017 ]
