Introduction
Thank you for purchasing the JBL P-20t
Power Series™ component tweeter.
We’ve organized this manual to make
your installation as simple and trouble-
free as possible. We suggest you read
through it completely before proceeding.
If, after having read it, you decide that
you would rather leave installation to a
professional, consult your JBL Power
Series Dealer.
Autosound at its Best
Your JBL P-20t tweeters are built to meet
the same rigorous standards of construc-
tion and performance that have long
established JBL’s renowned home and
professional speaker systems. The P-20t
incorporates advanced materials and con-
struction especially suited to the unique
acoustic environment of modern vehicles.
They are engineered to provide excellent
dispersion, frequency response, and
power handling, along with minimum
size. Angle- and flush-mounting options
are included for optimizing placement
within the vehicle. Your P-20t tweeter has
been designed using a combination of
technologies that bring high value to high
performance.
The dome used in your P-20t is manufac-
tured from a proprietary material known
as Titanium Composite. This material
combines the control and damping of an
advanced polymer with the reinforcing
stiffness of vapor-deposited titanium to
prevent breakup at high levels.
The P-20t utilizes a powerful neodymium
magnet structure. Neodymium not only
improves the P-20t's performance, but
allows that performance to be built into a
small package, increasing installation
possibilities.
By following the installation recommen-
dations and suggestions included in this
manual, you will be assured of many
years of trouble-free enjoyment from
your Power Series components.
Important Paperwork
Before proceeding, be sure to put the
sales receipt from your JBL P-20t tweeter
purchase in a safe place. It is necessary
to validate your Limited Warranty.
Having access to the receipt is also
valuable for insurance purposes
and when it comes time to resell
your vehicle.
Installation
The tweeter has been supplied with both
surface- and flush-mount brackets.
Figures 1 and 2 show the proper way to
flush- and surface-mount the tweeter.
The mounting hole diameter of the
flush-mount frame is 1-7/16".

System Design
The P-20t, with its built-in in-line
crossover, is designed to provide added
high-frequency performance to any
mobile audio system.
The P-20t may be used as the primary
tweeter in a system or as an add-on
tweeter or super tweeter used to improve
the high-frequency response of an
existing system.
The in-line crossover acts as a high-pass
filter as well as a protection device that
keeps the tweeter from being overexerted
by low frequencies that it was not
designed to reproduce.
Under normal circumstances this
crossover should not be bypassed or
removed for any reason. Bypass the
installed capacitor only when using an
outboard active crossover or a custom-
built passive crossover set above 5kHz.
Component Placement
Because of the P-20t’s small size and
extremely versatile mounting options,
there is an almost infinite number of
placement options to achieve excellent
sound quality in any vehicle. Please
consider the following statements to
help you get the most from your system.
1. The most spacious stereo image is
achieved when the P-20ts are placed
as far apart as possible.
2. The best center image will be achieved
when the distances from the left
speaker and the right speaker are as
equal as possible from your listening
position. This is most easily achieved
by placing the P-20ts as far forward as
possible.
3. Treble is directional in nature. This
means that high frequencies are
reduced as you move off the tweeter’s
axis. The angle mounts will allow the
P-20ts to be pointed across the car to
the listener on the opposite side (as
shown in Fig. 3). This will make each
listener slightly off-axis to the tweeter
that is closer to that listener, which
helps to compensate for the fact that
the listener is always closer to one
tweeter than to the other.
4. The best system integration is
achieved when the tweeter is mounted
close to the midrange speaker. This
helps smooth the transition from the
midrange and tweeter crossover point.
Choosing mounting locations that satisfy
all the above criteria will provide the most
satisfying performance.

Tweeter Output Level
The P-20t is a very efficient tweeter. If
there is a need to lower the tweeter out-
put, a 4-ohm / 5-watt resistor can be
connected in series (before capacitor)
with the P-20t, as shown in Fig. 4.

To avoid short circuits, make
sure that heat-shrink tubing or
electrical tape is used to cover all
exposed wiring.
Installation
Warnings and Tips
Be careful not to cut or drill into fuel
tanks, fuel lines, brake or hydraulic lines,
vacuum lines or electrical wiring when
working on your vehicle. Inspect behind
panels before you cut or drill.
Do not use the P-20ts unmounted.
Failure
to secure this product could result in
damage or injury, particularly in the event
of an accident.
Always disconnect the ground wire from
the battery before doing any work on the
vehicle.
