2.5-Way Center-Channel Loudspeaker: The MartinLogan Motion 50XT
center-channel loudspeaker employs a 2.5-way speaker design and features MartinLogan's
advanced resolution Folded Motion XT tweeter and dual 6.5" aluminum cone
midbass woofers. Combining these three drivers together creates a dynamic full-range
sound with an expansive soundstage.
- Folded Motion Tweeter: MartinLogan's Folded Motion XT
tweeter helps give the Motion 50XT 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 1.25" x 2.4" Folded Motion
XT 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°x30°)
to create a realistic and carefully etched sound stage.
- Dual Aluminum Cone Woofers w/ Bass Port: The MartinLogan
Motion 50XT center-channel loudspeaker features two high-excursion 6.5" aluminum cone
woofers with a cast basket housed in a non-resonant asymmetrical chamber with
a rear-firing bass port. The aluminum cone woofers use a rigid structured
dust cap to reduce cone break-up and distortion. Pairing dual 6.5" woofers
with a rear-firing bass port provides 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 50XT loudspeaker features a precision crossover (900Hz/2.2kHz)
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 MDF Cabinet: Complementing the Motion 50XT
loudspeaker's sonic accuracy is its solidly constructed 3/4" thick MDF cabinet.
The cabinet is finished in either
high-gloss piano black or black cherrywood, and includes MartinLogan's signature perforated grille.
The Motion 50XT speaker's elegant
and timeless look will blend into almost any decor. The speaker cabinet also
features rounded edges and a gently tapered top.
Bi-Wiring/Bi-Amping: Using the dual posts, you can bi-wire
or bi-amp the speaker. Bi-wiring or bi-amping the speaker provides improved bass
& treble performance. If you decide to bi-wire or bi-amp, you must remove the
jumpers between the terminal posts (failure to do this could result in damage to
your amplifier and loudspeakers).
- Bi-Wiring: Bi-wiring can provide noticeable
improvements in the overall transparency of your loudspeakers. Run separate
speaker wires to the low & high frequency drivers from a single amplifier
(the upper set of binding posts are for the high frequency drivers; the
lower set of binding posts are for the low frequency drivers).
- Bi-Amping: Bi-amping allows you to use separate
amplifiers for the high & low frequency sections of your loudspeaker for
greater dynamic range & lower distortion. We recommend that your separate
amplifiers have identical gain to preserve the speaker's voicing balance.
Note: 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 50XT 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 four rubber
self-adhesive feet to help secure it in place, prevent slippage, and reduce
Break-in Period: Allow approximately 72 hours of break-in at
90 dB (moderate listening levels) before any critical listening.
