MartinLogan SLMX3 Passive 3-Channel Home Theater Sound Bar

"A Bargain at Double the Price"

MartinLogan's Motion SLM X3 three-channel soundbar design gives you a complete stereo and center soundstage, with three Folded Motion tweeters and six 4" ultra-slim fiber cone woofers.

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 stunning dynamic range and jaw-dropping clarity.

"Even if it sold for double its price, I would still consider it a bargain for the sound," raves Francisco Licon in his November 6, 2017 review for Secrets of Home Theater and High Fidelity. "If you need a surround speaker or just better sound for your TV, do not hesitate. Buy it now!"

"In MartinLogan's Motion SLM X3 you get superb sound quality in three discrete channels with separation that's among the best I've heard from anything like a soundbar, and with clarity, compliments of ML's Folded Motion tweeter, that may be unrivaled -- again, for a soundbar," reports Kevin East, SoundstageXperience.com, October 2017.

The Audible Truth About Thin TVs

TV manufacturers are pushing the physical limits of electronics, making TVs that are thinner than ever at less than 2-inches 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 speakers provides a clean, easy to install solution for elevating the aural experience that has been sacrificed with ultra-thin TV technology.

Slender Profile and Stunning Performance

The secret to the Motion SLM's outstanding performance is the innovative dual 4-inch, ultra-slim fiber cone woofers and dual 4-inch high-velocity passive bass radiators, paired with a Folded Motion tweeter to create stunning acoustical alchemy 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 cabinet is only 1.45-inches thin, for a total wall protrusion of 1.83-inches with magnetic grille and included wall mount bracket.

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 wall-mounted and playing in no time. While we created Motion SLM speakers to wall mount next to ultra-flat panel TVs, that's not their only application.

For applications where on-wall installation is not an option, the SLM X3 includes a "kick-stand" brackets that attaches to the back of the cabinet, allowing it to free-stand beneath a television.
