In-Wall Loudspeaker: The ElectroMotion IW in-wall
loudspeaker features MartinLogan's Folded Motion tweeter and a 6.5" aluminum
cone woofer with cast aluminum basket that provides powerful low-frequency bass
extension. This stealthy in-wall speaker blends seamlessly into any home thanks
to it's ultra-low profile, micro-perforated grille with no visible bezel.
Folded Motion Tweeter: MartinLogan's Folded Motion tweeter
helps give the ElectroMotion IW in-wall speaker 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.
Aluminum Cone Woofer: The ElectroMotion IW in-wall speaker
employs a 6.5" aluminum cone woofer with a rubber surround, concave dust cap,
and cast aluminum basket for detailed midrange and powerful low-frequency bass
Precision Vojtko Crossover: Carefully hand-built using only
the finest polyester capacitors and air-core coils, the crossover employ's
MartinLogan's proprietary Vojtko topology for vanishingly low distortion and
seamless driver integration. This precision-tuned network preserves even the
most microscopic sonic nuances while handling the full dynamics of any source.
Spring-Post Connectors: The MartinLogan ElectroMotion IW
features two spring-post connectors to attach your speaker wire. The
spring-posts will accept bare wire (16- to 12-gauge) and pin-connectors.
Robust Mounting Locks: A robust mounting-lock system allows
quick, trouble-free installation. When not in use, the constant-control mounting
locks are held securely within a self-contained housing. When moved into place
during installation, they couple the speaker's chassis firmly to the wall. And
if the speaker is ever removed, the locks retract and latch themselves back in
Ultra-Low Profile Grille: The MartinLogan EM-IW features an
ultra-low profile, paintable micro-perforated grille with no visible bezel for a
near invisible integration into any wall. A magnetic system secures the grille
easily into place, reducing the risk of warping or damage during installation.
Applications & Placement: The EM-IW is suitable for almost
any application in average to small rooms. Ideal for use in a multi-channel home
theater as a surround speaker, in a kitchen as 2-channel stereo speaker, or in a
hallway as part of a distributed audio system. This MartinLogan in-wall speaker
offers superb imaging and flexible placement in nearly any location. However,
for best performance and imaging place speakers equidistant from one another and
avoid physical obstructions between the speaker and primary listening position.
Installation Dimensions: The in-wall speaker has an overall
measurement of 8.5" (w) x 11" (h) x 3.9375" (d). It requires a cut-out of 7.875"
(w) x 10.25" (h) and a mounting depth of 3.8125" behind the wall surface. The
speaker only protrudes 0.125" from the wall.
Break-in Period: Allow approximately 72 hours of break-in at
90 dB (moderate listening levels) before any critical listening.
