The result is smooth, refined sound with extraordinary dynamic range and astonishing clarity.

The Audible Truth About Thin TVs

TV manufacturers are pushing the physical limits of electronics, making TVs thinner than ever at less than 2 inches from the wall. While they look great, creating a thinner TV means compromising on built-in speakers; tiny drivers, cheaper parts, reduced cabinet volume, and placement behind the TV create an unnatural, lifeless sound. Worse yet, these speakers are typically underpowered and easily distort when you turn up the volume. Motion SLM speakers offer a clean, easy-to-install solution to elevate the acoustic experience that has been sacrificed with ultra-thin TV technology.

Slim Profile, Stunning Performance

The secret to the Motion SLM's exceptional performance is its innovative 4-inch ultra-thin fiber cone woofers and dual 4-inch high-velocity passive bass radiators, paired with a Folded Motion tweeter to create a stunning acoustic alchemy typically found in much larger speaker systems. Hidden discreetly beneath the grille, the drivers are held firmly in place by a solid, black-anodized brushed aluminum baffle. The gloss black SLM cabinet is just 1.45 inches thin, for a total wall projection of 1.83 inches with the magnetic grille and included wall mount bracket.

Wall or Shelf Versatility

With keyhole slots on the speaker's rear panel that easily attach to the included wall mount bracket, you'll have the SLM wall-mounted and playing in no time. While we've created Motion SLM speakers to wall-mount next to ultra-flat-screen 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

The folded motion tweeters have an 80° x 80° dispersion pattern, allowing the SLM and SLM XL to sound exactly the same in either a horizontal or vertical orientation, making them perfect for Left-Center-Right (LCR) system applications. The grille logo is magnetic and can move and rotate into the right aesthetically pleasing position in any orientation. The SLM and SLM XL both include a base designed for vertical applications, allowing the speakers to sit on a shelf or equipment cabinet.
