Placement Options (All Models) - Martin Logan Motion XT XTW6 Mode D'emploi

When choosing placement follow these simple recommendations. Keep in mind these are
just recommendations and your unique installation requirements may dictate otherwise:
• Place a minimum of 12-inches (30cm) from any wall corner.
• Place fronts/centers equidistant between 10–14 feet (3–4.3m) from the listening position.
• XTC8, and XTC8-HT. Install in-ceiling only.

The Motion XT series architectural speakers feature MartinLogan's highest performance
Folded Motion Tweeter, the FMT XT. In addition to the increased performance capabilities
over our standard size FMT, this unique thin film tweeter features an even further controlled
dispersion pattern of 80° by 30°. This controlled "cone of sound" even further reduces
undesirable acoustic interactions and can be extremely useful in avoiding sound reflections
in the room which would otherwise result in diminished sound quality. For optimal
performance, attention should be paid to the mounting location of the speaker to help
ensure that the primary listening area is within the dispersion pattern of the tweeter. Keep in
mind, the farther away the listener is from the speaker, the wider the coverage area of the
tweeter becomes. Because of the unique dispersion of the FMT XT tweeter, the dispersion or
coverage area of Motion XT CI in-wall speakers can be adjusted by positioning the tweeter
either horizontally or vertically. By default the in-wall models ship ready to be installed
with the tweeter in the vertical orientation, providing an 80° Horizontal x 30° Vertical
dispersion pattern. Depending on your unique room layout, seating position, and installation
requirements, the tweeter can be used in either horizontal or vertical orientation to provide
the best coverage for your particular needs. For example, when installing an in-wall speaker
higher up on the wall (well above the seating area height) it may be more beneficial to
orient the tweeter in the "horizontal" position so the dispersion pattern then becomes 30°
Horizontal by 80° Vertical to ensure the primary listening area is within the coverage of
the tweeter. In other words, the FMT XT provides an 80° x 30° dispersion and you can
decide which orientation is more appropriate for your system to provide the best coverage
and performance. The more controlled 30° dispersion side can be used to help eliminate
unwanted sound reflections or help reduce unwanted "sound leakage" into other areas of
the home, especially in open floor plans. Controlled Dispersion is a tool to help deliver better
sound quality where it actually matters, your ears! So feel free to experiment with both
options to help decide which is the right choice for your installation.
