3-Channel Passive Soundbar: The slender MartinLogan Motion
SLM X3 soundbar features three advanced resolution Folded Motion tweeters and six
4" high-excursion paper cone woofers for maximum
controlled low-end bass extension; all in an ultra-slim, 3-channel soundbar
design for flat-panel TVs, giving you a complete stereo and center soundstage.
Each channel (Left/Center/Right) features one Folded Motion tweeter and two 4"
high-excursion paper cone woofers. The Motion SLM X3 provides a clean, easy to install solution for elevating the
audio experience that has been sacrificed with flat-panel TV technology.
Innovative Driver Design: The secret to the Motion SLM X3's outstanding
performance is three 1" x 1.4" Folded Motion tweeters paired with six innovative 4" ultra-slim paper cone woofers
to create a stunning 3-channel soundstage.
- 3 Folded Motion Tweeters: Three of MartinLogan's Folded Motion
tweeters help give the Motion SLM X3 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 tweeters work 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.
- Six High-Excursion Paper Woofers: Six 4"
high-excursion paper cone woofers provide rich, detailed midrange and midbass that complement MartinLogan's Folded Motion tweeters perfectly.
Precision Crossovers: To seamlessly blend the audio output
from the high frequency driver (tweeter) and the midbass drivers (woofers), the
Motion SLM X3 features a precision 3000Hz 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 Sealed Cabinet: The Motion SLM X3 features an
ultra-slim sealed cabinet with a high-gloss black finish and comes with a
magnetic black cloth grille. Hidden discretely underneath the magnetic grille,
the drivers are held securely in place by a solid, black-anodized brushed
3 Pair Of Spring-Post Terminals: The SLM X3 is equipped with a set of
spring-post terminals for each channel to connect to your AV receiver's Front
Left, Front Right, and Center speaker output terminals. These spring-post
terminals will accept bare speaker wire from 16AWG to 12AWG. Due to the position
of the spring-post terminals they will not accept banana plugs or
pin-connectors. The SLM X3 is compatible with 4, 6, and 8 ohm compatible
receivers and amplifiers.
Mounting Options: With keyhole slots on the passive soundbar speaker's
back panel that attach easily to the included wall bracket, the SLM X3 can be
wall-mounted under or above your flat-panel TV. While MartinLogan created the
Motion SLM X3 soundbar to wall mount next to flat-panel TVs, that's not its only
application. Included with the passive soundbar speaker are feet that allow it
to sit on a shelf or equipment cabinet.
