Ultra-Slim Folded Motion® Speakers
The slender Motion SLM speakers feature an advanced resolution Folded Motion™ tweeter, two 4-inch high-excursion fiber cone woofers and two passive bass radiators for maximum controlled low-end bass extension - all in an ultra-slim profile designed expressly for super-thin TVs.  For even greater low-end bass extension, step up to the Motion SLM XL which adds two extra 4-inch passive radiators and aesthetically matches 65-inch and larger TV sizes.  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.

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.

Grille Options
Both Motion SLM & SLM XL have optional paintable metal grille covers (sold separately) that can blend into your room for a stealthy aesthetic.

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 wall-mounted and playing in no time. While MartinLogan created Motion SLM speakers 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 (* SLM or SLM XL only).

The Perfect LCR System
Folded Motion tweeters have an 80° x 80° dispersion pattern, which allows SLM and SLM XL to sound exactly the same in a horizontal or vertical orientation, making them perfect for Left-Center-Right (LCR) system applications. The logo on the grille is magnetic and can move and rotate to the proper aesthetically pleasing location in any orientation. SLM and SLM XL both include a base designed for vertical applications, allowing the speakers sit on a shelf or equipment cabinet.
