Two-Way Speaker/Passive Radiator Design: The secret to the
Motion SLM-XL ultra-slim speaker's outstanding performance is the innovative dual
4" ultra-slim fiber cone woofers and quadruple 4" high-velocity passive bass
radiators, paired with a Folded Motion tweeter to create smooth, refined sound
with stunning dynamic range and excellent clarity.
- Folded Motion Tweeter: MartinLogan's Folded Motion
tweeter helps give the Motion SLM-XL ultra-slim loudspeaker its natural,
realistic high frequency sound. Lightning fast transient response, combined
with a large surface area (8x that of a typical 1" dome tweeter) creates
clear, dynamic, and precise sound. The 1" x 1.4" Folded Motion tweeter works
by moving air (which creates sound) perpendicular to the folded ridges of
the diaphragm, similar to how an accordion works. This extremely low mass
diaphragm "squeezes" air and requires almost 90% less excursion than the
typical 1" dome tweeter, which drastically minimizes distortion while
providing a lightning fast response time. The increased surface area also
provides a wide, yet controlled sound dispersion (80°x80°)
to create a realistic and carefully etched sound stage.
- Dual Ultra-Slim Woofers + Quadruple Passive Bass Radiators: Two 4"
paper cone woofers are coupled with four 4" paper cone passive radiators to
provide rich, detailed midrange and midbass that complement MartinLogan's
Folded Motion tweeter perfectly.
Precision Crossovers: To seamlessly blend the audio output
from the high frequency driver (tweeter) and the midbass drivers (woofers), the
Motion SLM-XL loudspeaker features a precision 3100Hz crossover utilizing custom
air core coil and low DCR steel laminate inductors, polyester film capacitors in
series, and low DF electrolytic capacitors in parallel.
Ultra-Slim Cabinet: The high-gloss black ultra-slim cabinet
is only 1.875" deep, for a total wall protrusion of 2.0" with the included wall
mount bracket. Hidden discretely underneath the grille, the drivers are held
securely in place by a solid, black-anodized brushed aluminum baffle.
Spring-Post Connectors: The MartinLogan Motion SLM-XL speaker
features two spring-post connectors to attach your speaker wire. The
spring-posts will accept bare wire (16- to 12-gauge) and pin-connectors. The
rubber caps on the spring-post connectors must be removed to use banana plugs.
Applications: The Folded Motion tweeter has an 80° x 80°
dispersion pattern, which allows the Motion SLM-XL ultra-slim speaker to sound
exactly the same in a horizontal or vertical orientation, making them perfect
for Left-Center-Right (LCR) system applications. Or, use them as rear surround
speakers. Because of its ultra-slim design, the Motion SLM-XL is perfect for
wall-mounting next to your flat-panel television.
Note: This speaker is not magnetically shielded and
therefore should not be placed directly beside or atop a CRT television.
Mounting Options: The MartinLogan SLM-XL loudspeaker can be
wall mounted next to your flat-panel TV using the keyhole slot on the back of
the speaker and the included wall-mount bracket. The speaker can be mounted
vertically or horizontally (for center-channel application) on your wall. While
MartinLogan created the Motion SLM-XL to wall mount next to a flat-panel TV, that's
not its only application. Also, included with the ultra-slim speaker is a curved
black base to allow them to sit vertically on a shelf, stand, or equipment
cabinet. In addition, the speaker includes two "kick-stands" that attach to the
back of the cabinet that allow you rest the loudspeaker horizontally on a flat
surface and use it as a center-channel speaker. Dimensions of speaker:
- Wall-Mounted: 6.4375.125" (w) x 34.125" (h) x
- Vertical Base: 10.0625" (w) x 36.625" (h),
- Horizontal Kick Stands: 34.125" (w) x 6.4375" (h) x
Note: The logo on the grille is magnetic and can move and
rotate to the proper atheistically pleasing location in any orientation.
Break-in Period: Allow approximately 72 hours of break-in at
90 dB (moderate listening levels) before any critical listening.
