Key Features

Ultra-Slim Folded Motion® Speakers
The slender Motion SLM X3's 3-channel soundbar design gives you a complete stereo and center soundstage, with three Folded Motion tweeters and six 4-inch ultra-slim fiber cone woofers.

Inspired Sound
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.

Slender Profile & 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.

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 X3 wall-mounted and playing in no time. While we created Motion SLM X3 soundbar to wall mount next to ultra-flat panel TVs, that's not their only application. Included with each speaker is are feet that allow them to sit on a shelf or equipment cabinet.
