    MartinLogan Ultra-Slim Motion SLM XL Black Speaker, Model SLMXL (Sold As Each)

    The slender Motion SLM & SLM XL speakers feature an advanced resolution Folded Motion™ tweeter, two 4-inch high-excursion fiber cone woofers and two passive bass radiators for maximum controlled low-end bass extension - all in an ultra-slim profile designed expressly for super-thin TVs.

    For even greater low-end bass extension, step up to the Motion SLM XL which adds two extra 4-inch passive radiators and aesthetically matches 65-inch and larger TV sizes.

    Inspired by MartinLogan's ultra-high-end electrostatic loudspeakers, the Motion Series was created to provide stunning sound for your ultimate-performance home theater or stereo. MartinLogan's dedicated in-house engineers carefully crafted the Motion Series to create an extremely affordable and compact product line that seamlessly blends our exquisite Folded Motion transducers with powerful, compact bass technology. The result is a smooth, refined sound with stunning dynamic range and jaw-dropping clarity.


    • 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 & SLM XL 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 wall-mounted and playing in no time. While we created the Motion SLM to wall mount next to ultra-flat panel 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.
    • The Perfect LCR System
      The Folded Motion tweeter has an 80° x 80° dispersion pattern, which allows the Motion SLM to sound exactly the same in a horizontal or vertical orientation, making them perfect for Left-Center-Right (LCR) system applications. The logo on the grille is magnetic and can move and rotate to the proper atheistically pleasing location in any orientation.
      Each speaker includes "kick-stand" brackets that attach to the back of the cabinet, allowing them to free-stand for center channel applications. The stands are easily adjustable with the provided screw feet.
