MartinLogan Motion SLM X3

Space-saving way to create a front soundstage for your TV setup

Most sound bars that we offer are completely self-contained, self-powered speaker systems. The MartinLogan SLM X3 sound bar is a different animal. Sure, it sports a slim, low-profile look that fits neatly into a TV setup. But it relies on the power (and TV connections) of a separate home theater receiver.

This passive loudspeaker takes the place of the front three speakers in a traditional home theater setup. The cabinet is under 2″ thick, so you can wall-mount it below a flat-panel TV and maintain a sleek, elegant look. And since MartinLogan didn’t have to pack amplification and extra circuitry inside, they’ve turned all their attention to the high-performance drivers.

Surprisingly full sound from a super-thin design

MartinLogan includes some of their most innovative drivers to make the most of the space they have. The headliners are the three Folded Motion™ tweeters — thin, accordion-like pleated diaphragms “squeeze” air to create sound. These tweeters are favorites here at Crutchfield for their focused and natural sound.

But you could argue that the heavy-lifters are the six 4″ ultra-slim mid/woofers. Somehow within the SLM X3’s thin cabinet, these drivers manage to deliver some serious midrange and bass. The result is full, dynamic sound that makes movies and music more enjoyable and engaging.
