MartinLogan Motion SLM Left/Center/Right Speaker – Gloss Black – Each

What You Need to Know

MartinLogan Sound, Less Than Two Inches Off the Wall

The MartinLogan Motion SLM is the slimmest speaker MartinLogan has ever built—a cabinet just 1.45 inches thin that hangs a mere 1.83 inches off the wall, bracket and grille included. Designed to physically and visually match today’s ultra-thin flat-panel TVs, it delivers the fast, detailed sound of MartinLogan’s celebrated Folded Motion tweeter where a soundbar would normally settle for less.

Finished in high-gloss black and sold individually, one SLM serves as a left, center, or right channel—build exactly the system you need.

The Folded Motion Tweeter

MartinLogan’s signature Folded Motion tweeter works like an accordion, gently squeezing air with a pleated diaphragm several times the surface area of a typical 1-inch dome—using about 90% less excursion. The result is lightning-fast transient response with vanishingly low distortion: the airy, effortless high end that made MartinLogan famous, from a speaker thinner than most picture frames.

Real Bass from an Impossibly Thin Cabinet

Two 4-inch high-excursion, ultra-slim woofers work with two 4-inch high-velocity passive radiators—all mounted in a rigid black-anodized brushed aluminum baffle—to produce output down to 110Hz from a cabinet under an inch and a half deep. A precision 2,600Hz crossover with air-core inductors and film capacitors keeps the handoff seamless.

One Speaker, Any Position

The SLM’s wide 80° x 80° dispersion means it sounds identical mounted vertically or horizontally—purpose-built for left, center, and right duty. The magnetic grille pops off and the logo rotates to suit any orientation, so every channel looks as intentional as it sounds.

Mounts Anywhere in Minutes

A wall-mount bracket is included, backed up by keyhole slots for direct hanging, and low-profile push-style terminals preserve the slim fit against the wall. Off the wall, the included curved base and kick-stand brackets let the SLM sit on a shelf or cabinet as a freestanding center channel.

Building Your System

Start with three SLMs across the front—or five around the room—and add a MartinLogan Dynamo subwoofer to cover the bottom octaves below the SLM’s 110Hz reach. At 94dB sensitivity with just 20 watts required, any AV receiver drives it with ease.

The SLM also blends seamlessly with MartinLogan’s Motion Series towers, and reviewers agree: SoundStage! called it “one of the best wall-mounted speakers I’ve reviewed… an easy recommendation.”

Frequently Asked Questions

How many do I need?
The SLM is sold each, so buy exactly what your system calls for: three for a front LCR stage, five for surround, or a single center channel to match existing speakers.

Do I need a subwoofer?
For movies and full-range music, yes—the SLM reaches down to 110Hz, and MartinLogan’s Dynamo subwoofers are the designed-for match to carry everything below.

How does it compare to the Motion SLM XL?
The SLM XL adds two more passive radiators in a taller cabinet for deeper bass and a visual match with 65-inch-plus TVs. The standard SLM is the choice for smaller displays and tighter spaces.

Who is the Motion SLM designed for?
It’s for the listener who wants genuine audiophile sound—not soundbar sound—from a system that all but disappears against the wall beside a thin flat-panel TV.
