The slender Motion SLM 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.
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 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.
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.
