BREAK IN
Allow approximately 72 hours of break-in at 90
dB (moderate levels) before any critical listening.
INSTALLING ON A FLAT SURFACE
If you have a surface that provides a wide, level,
and stable platform, the speaker can be placed
directly on top. When using the speaker in this
configuration, affix the pads to the bottom of the
speaker at the rear contact points (fig. 2). Note:.
This speaker is not magnetically shielded and
therefore should not be placed directly beside or
atop a CRT television.
Toe-In:.When installed on a surface and used as
front channels we recommend aiming your speak-
ers towards the primary listening position.
ConneCtion
WARNING! Turn your amplifier
off before making or breaking any
signal connections!
Use the best speaker cables you can. The length
and type of speaker cable used in your system will
have an audible effect. Under no circumstance
should a wire of gauge higher (thinner) than #16
be used. In general, the longer the length used,
the greater the necessity of a lower gauge, and
the lower the gauge, the better the sound, with
diminishing returns setting in around #8 to #12.
Connections are done at the signal input section
on the rear electronics panel of the Motion 15.
Use spade connectors for optimum contact and
ease of installation. Hand tighten the binding
posts, but do not overtighten—do not use a tool to
tighten the binding posts.
Be consistent when connecting the speaker cables
to the signal input terminals. Take care to assign
the same color cable lead to the (+) terminal on
both the left and right channel speakers. If bass is
nonexistent and you cannot discern a tight, coher-
ent image, you may need to reverse the (+) and
(–) leads on one speaker to bring the system into
proper polarity.
