Wiring
Use 2-conductor stranded
type, insulated wire to connect
the 08GTi to it’s crossover, and
the crossover to the amplifier.  A
minimum wire gauge of 18AWG
is recommended, with larger size
suggested for wire runs longer
than 10 feet.
The polarity — the positive/
negative orientation of the con-
nections for every speaker to
amplifier connection must be
consistent from left to right chan-
nel to assure proper imaging and
optimum frequency response.
This does not mean that the

08GTi should always be con-
nected in the same polarity as
the midrange however.  It is pos-
sible, that due to the difference
in the distance the sound travels
from the midrange to your ears
compared to the distance from
the tweeters in a typical system,
and the short wavelengths of
sound at the crossover frequen-
cy, that a connection where the
tweeters are connected in
reverse polarity from the other
drivers in the system may actu-
ally result in better sound.
Because there is no way to
accurately predict this before
installation, we recommend that
you try the connection both
ways, and leave it in the polarity
that gives the smoothest audible
transition between the midrange
and tweeter.  The JBL standard
for polarity marking uses the
solid red wire as positive (+) and
the black striped wire as nega-
tive (–).
System Connections:
There are a variety of sys-
tem options available with the
08GTi.  The simplest configura-
tion is to use the 08GTi
