Automotive Tweeter Owner’s Manual GTO15T
GTO SERIES
Introduction
Thank you for choosing the JBL
GTO15T. These tweeters have been
designed to provide smooth highfrequency reproduction, high power
handling and ease of installation.
Please read this manual thoroughly
before you begin your installation.
It includes information that will
make your installation as simple
and trouble-free as possible. Also,
don’t forget to send in your warranty
registration card, and keep your
sales receipt somewhere safe in
case you need warranty service.
About These Instructions
Installation of automotive stereo
components can require extensive
experience with a variety of mechanical and electrical procedures.
Although these instructions explain
how to install GTO15T tweeters in a
general sense, they do not show the
exact installation methods for your
particular vehicle. If you feel you do
not have the experience, do not
attempt the installation yourself,
but instead ask your authorized JBL
car audio dealer about professional
installation options.
Loud Music and Hearing
Playing loud music in an automobile
can permanently damage your hearing, as well as hinder your ability to
hear traffic. The maximum volume
levels achievable with JBL speakers,
combined with high power amplification, may exceed safe levels for
extended listening. We recommend
using low volume levels when driving.
JBL accepts no liability for hearing
loss, bodily injury, or property damage as a result of use or misuse of
this product.
About the Crossover
Passive-crossover design involves
precise circuit design and component selection. Moreover, a welldesigned crossover circuit provides
an intended electrical response,
when combined with the electrical
properties of the speaker, to provide
a particular acoustic response.
Each enclosed crossover has been
optimized to provide a flat response
when used with a GTO15T tweeter.
Do not use another brand or type
of passive crossover, or connect
more than one tweeter to a
crossover. Doing so may damage
the tweeter.
About Placement
Figures 1 and 2 show possible
speaker placements with Figure 1
being more desirable. We recommend using the kick panel for
mounting to obtain the best staging
and imaging in most vehicles.
