BREAK IN
Allow approximately 72 hours of break-in at 90 dB
(moderate listening levels) before 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 rubber 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.
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.
A variety of cables are available whose manufactur-
ers claim better performance than standard heavy
gauge wire. We have verified this in many cases,
and the improvements available are often more
noticeable than the differences between wires of dif-
ferent gauge. The effects of cables may be masked
if equipment is not of the highest quality.
Connections are done at the signal input section
on the rear electronics panel of the speaker. 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, coherent image, you
may need to reverse the (+) and (–) leads on one
speaker to bring the system into proper polarity.
