"Best Sounding at Anywhere Near the Price"
The slender Motion SLM XL speaker is the newest addition to MartinLogan's award-winning Motion® Series. It features an advanced resolution Folded Motion™ tweeter, two 4" high-excursion fiber cone woofers, and four passive bass radiators for maximum controlled low-end bass extension. And it has an ultra-slim profile designed expressly for super-thin TVs.
"The Motion SLM-XL speakers are the best-sounding on-wall speakers I've heard at or anywhere near their price," raves Myron Ho, HomeTheaterReview.com, June 2014. "If you are looking for a great pair of low-profile speakers to match with your flat- panel TV, you owe it to yourself to take the SLM-XLs for a spin and see if they're right for you."
Inspired by High-end Electrostatics
Inspired by MartinLogan's ultra-high-end electrostatic loudspeakers, the Motion Series was created to provide stunning sound for your ultimate-performance home theater or stereo. MartinLogan's dedicated in-house engineers carefully crafted the Motion Series to create an extremely affordable and compact product line that seamlessly blends our exquisite Folded Motion transducers with powerful, compact bass technology. The result is a smooth, refined sound with impressive dynamic range and jaw-dropping clarity.
The Sound Truth About Thin TVs
TV manufacturers are pushing the physical limits of electronics, making TVs that are thinner than ever at less than 2" from the wall. While they look great, creating a thinner television means making compromises to the built-in speakers. Tiny drivers, cheaper parts, reduced cabinet volume, and placement behind the TV create unnatural, lifeless sound. Worse yet, these speakers are usually underpowered, and easily distort when you turn up the volume. Motion SLM XL provides a clean, easy-to-install solution for elevating the sonic experience that has been sacrificed with ultra-thin TV technology.
Slender Profile and Stunning Performance
The secret to the Motion SLM-XL's outstanding performance is the innovative dual 4", ultra-slim fiber cone woofers and four 4" high-velocity passive bass radiators, paired with a Folded Motion tweeter to create big sound typically found in much larger speaker systems. Hidden discretely underneath the grille, the drivers are held securely in place by a solid, black-anodized brushed aluminum baffle. The high-gloss black SLM-XL cabinet is a mere 1.89" thick with magnetic grille.
Folded Motion Tweeter
The 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 percent less excursion than the typical 1" dome tweeter, which drastically minimizes distortion while providing a lighting fast response time. The increased surface area also provides a wide, yet controlled sound dispersion to create a realistic and carefully etched sound stage.
Lightning fast transient response, combined with a large surface area (several times that of a typical 1" dome tweeter) creates clear, highly dynamic, and precise sound.
On-Wall or On-Shelf Versatility
With keyhole slots on the speaker's back panel that attach easily to the included wall bracket, you'll have the SLM-XL wall-mounted and playing in no time. While MartinLogan created the Motion SLM to wall mount next to ultra-flat panel TVs, that's not their only application. Included with each speaker is a curved black base to allow them to sit on a shelf or equipment cabinet.
The Perfect LCR System
The Folded Motion tweeter has an 80-degree x 80-degree dispersion pattern, which allows the Motion SLM-XL to sound exactly the same in a horizontal or vertical orientation. This makes it perfect for Left-Center-Right (LCR) system applications. The logo on the grille is magnetic and can move and rotate to the proper atheistically pleasing location in any orientation.
Each speaker includes "kick-stand" brackets that attach to the back of the cabinet, allowing them to free-stand for center channel applications. The stands are easily adjustable with the provided screw feet.

"The Motion SLM-XL speakers are the best-sounding on-wall speakers I've heard at or anywhere near their price. The speaker's versatility for use as a center channel and/or surround -- as well as its ability to be placed on the wall, desktop, or floor -- make it a superb value. If you are looking for a great pair of low-profile speakers to match with your flat- panel TV, you owe it to yourself to take the SLM-XLs for a spin and see if they're right for you."
