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.

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.

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 we 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.

Press For Motion SLM

MartinLogan Motion SLM On-Wall Loudspeakers and Dynamo 700w Subwoofer

"I see it as a gateway speaker to the MartinLogan brand... it’s one of the best wall-mounted speakers I’ve reviewed. They’re beauties to look at, with a high-gloss finish to match that of any flat-panel TV. The Folded Motion Tweeter is more refined than those used in other wall-mounts I’ve heard, and the Motion SLMs produced much better depth of image than other on-walls... All in all, an easy recommendation."

Great speaker, I already had two Motion SLM XL and fell in love with them, I was looking for a center channel speaker and after buying other two I finally choose the SLM, the high frequency drive has no competitor unless you pay a lot more, folded motion, the best relation quality price ever. Super slim design, no tower on the floor, easy set up, modern look, incredibly loud at 94 dB, you won't believe this sound pressure level is coming of this flat on wall speaker (you has te option of using the stand),. You are going to need a subwoofer to went below 110 Hz but if you are buying this beauty, you can pay $150 for a Polk Audio subwoofer at least, and upgrade your sub later if you want more bass. I'm not buying a speaker with a high frecuency drive if it is not a folded motion one, forget the manufacturer advertising, listen to the speaker if you can before buying it, compare and then choose the one you like. For the price it is hard to find a beter slim/flat speaker, it is not cheap, but compared to where the prices can clime, I'll buy Martin Logan forever.
