Our Product Research Team
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 30 center channel 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 Aluminum Cone Woofers w/ Rear-Firing Port: Two 5.5" aluminum cone
woofers with a cast polymer basket housed in a non-resonant asymmetrical chamber
flank the Motion 30 center channel speaker's Folded Motion tweeter. The aluminum
cone woofers use a rigid structured dust cap and butyl rubber surround to reduce
cone break-up and distortion. The two 5.5" woofers are paired with a rear-firing
bass port to deliver higher output and audibly richer, deeper bass performance.
Precision Crossover: To seamlessly blend the audio output
from the high frequency driver (tweeter) and the two midbass drivers (woofer),
the Motion 30 loudspeaker features a precision crossover utilizing custom air
core coil and low DCR steel laminate inductors, polyester film capacitors in
series, and low DF electrolytic capacitors in parallel.
High-Gloss Cabinet: Complementing the Motion 30
loudspeaker's sonic accuracy is its elegant, yet understated styling. A
high-gloss, piano black or black cherrywood finish, along with MartinLogan's
signature perforated grille, give the Motion 30 speaker an elegant and timeless
look that will blend into almost any decor. The speaker cabinet also features
smooth, rounded edges.
Binding Posts: MartinLogan's proprietary tool-less binding
posts simplify cable connection and management. The binding posts will accept
bare wire (16- to 10-gauge), pin-connectors, spade-connectors, and banana plugs
Placement: The MartinLogan Motion 30 should be centered below or above
your television on flat-surface; such as a table-top, stand, cabinet, or shelf.
The center channel speaker comes with 4 rubber self-adhesive feet to help secure
it in place, prevent slippage, and reduce vibration.
Break-in Period: Allow approximately 72 hours of break-in at
90 dB (moderate listening levels) before any critical listening.
