Product Description

The slender Motion 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.

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 XL provides a clean, easy to install solution for elevating the aural experience that has been sacrificed with ultra-thin TV technology.

Grille Options

Both Motion SLM & SLM XL have optional paintable metal grille covers (sold separately) that can blend into your room for a stealthy aesthetic.
