The MartinLogan Motion SLM is an ultra-slim on-wall speaker designed to deliver premium home theater performance while complementing today's ultra-thin televisions. Measuring less than two inches deep, it combines MartinLogan's renowned Folded Motion® Tweeter with dual 4-inch woofers and dual passive radiators to produce detailed highs, natural vocals, and impressive bass performance from an exceptionally compact enclosure. Its elegant design makes it ideal for installations where traditional speakers would be too large or visually intrusive.
At the heart of the Motion SLM is the Folded Motion® Tweeter, which moves air far more efficiently than a conventional dome tweeter to deliver faster transient response, lower distortion, and remarkable clarity. Combined with MartinLogan's precision-engineered crossover network, the speaker creates a spacious soundstage with accurate imaging and consistent tonal balance for both music and movies. The 80° × 80° dispersion pattern ensures excellent performance whether the speaker is installed vertically as a left or right channel or horizontally as a center speaker.
The Motion SLM is engineered for installation flexibility. It includes both a low-profile wall-mount bracket and a tabletop stand, allowing it to integrate seamlessly into virtually any entertainment setup. A magnetic grille with a repositionable MartinLogan logo ensures a clean appearance regardless of speaker orientation, while the ultra-slim cabinet blends effortlessly into modern living spaces.
Whether used individually for stereo playback or as part of a complete left-center-right home theater system, the Motion SLM delivers the signature MartinLogan sound in an elegant architectural form. Its combination of slim styling, installation versatility, and high-performance audio makes it an excellent choice for listeners seeking premium sound without sacrificing aesthetics.
