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.

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 X3 wall-mounted and playing in no time. While we created Motion SLM X3 soundbar to wall mount next to ultra-flat panel TVs, that's not their only application. Included with each speaker is are feet that allow them to sit on a shelf or equipment cabinet.
