At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Folded Motion Tweeter: MartinLogan's Folded Motion Tweeter
helps give the Motion 2 bookshelf 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
to create a realistic and carefully etched sound stage.
3.5" Poly Cone Woofer: The MartinLogan Motion 2 loudspeaker
features a 3.5" poly cone woofer with a stamped steel basket housed in a
non-resonant asymmetrical chamber. The poly cone woofer uses a rigid structured
dust cap to reduce cone break-up and distortion. This 3.5" cone woofer provides
rich, detailed midbass.
Precision Vojtko Crossover: To seamlessly blend the audio output
from the high frequency driver (tweeter) and the midbass driver (woofer), the
Motion 2 loudspeaker features a precision Vojtko crossover (2800Hz) utilizing custom air
core coil and low DCR steel laminate inductors, polyester film capacitors in
series, and low DF electrolytic capacitors in parallel.
Curved High-Gloss Black Sealed Cabinet: Complementing the Motion 2
loudspeaker's sonic accuracy is its elegant, yet understated styling. A
high-gloss, piano black finish and subtle curves, along with MartinLogan's
signature perforated grille, give the Motion 2 speaker an elegant and timeless
look that will blend into almost any decor. The cabinet is an acoustic
suspension design (sealed) for tighter, accurate midbass.
Spring-Post Connectors: The MartinLogan Motion 2 speaker
features two spring-post connectors to attach your speaker wire. The
spring-posts will accept bare wire (16- to 10-gauge), pin-connectors, and banana
plugs (single only). The rubber caps on the spring-post connectors must be
removed to use banana plugs.
Versatile Mounting Options: The MartinLogan Motion 2
bookshelf loudspeaker can simply be placed on a table-top, stand, shelf, or
other flat surface. Four self-adhesive rubber feet are included for safe and
secure placement. Using the included keyhole-slot bracket, you can wall-mount
the speaker at two different angles. This means you can point sound directly
toward the desired listening area for high or low wall mounting applications. In
addition the Motion 2 is fitted with a 1/4"-20 threaded insert which allows you
to hang the speaker on the wall using optional articulating wall-mount brackets
- If the Motion 2 is being mounted at approximately ear-level, the speaker
should be oriented with the tweeter at the top. This will disperse sound
directly towards the desired listening area.
- If the Motion 2 is be mounted above ear-level, the speaker should be
oriented with the tweeter at the bottom. This will disperse the sound down
at a 20° angle towards the listening area.
