Ultra-Slim Folded Motion® Speakers

SLM X3

Horizontal, On-wall or Off-wall

Slender Profile and Stunning Performance. The secret to the outstanding performance

of the Motion SLM and SLM XL are the innovative dual 4-inch, ultra-slim fiber cone woofers

and 4-inch high-velocity passive bass radiators, paired with a Folded Motion tweeter. Motion
SLM X3’s 3-channel soundbar design ups the ante with three Folded Motion tweeters and six 4-inch ultra-slim
fiber cone woofers. The result is 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 mounted flush within the speaker’s high-gloss black cabinet. The speakers are less than
2-inches deep when installed on-wall with the magnetic grilles and low-profile wall mount brackets.

The Perfect for Today’s Flat Screen Televisions. Folded Motion tweeters have an 80° x 80°

dispersion pattern, which allows SLM and SLM XL 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. SLM and SLM XL both
include a base designed for vertical applications, allowing the speakers sit on a shelf or equipment cabinet.
For applications where on-wall installation is not an option, SLM, SLM XL, and SLM X3 include “kick-stand”
brackets that attach to the back of the cabinet, allowing them to free-stand beneath a television.
