A Few Words
About Enclosures
The enclosure or box that you
choose for your Power Series
woofer will define the sound that
will ultimately come out of it.
The size of the box and tuning
frequency of port tubes in vented
enclosures dictate the lowfrequency performance and
output capability of your system.
The flexibility designed into the
Power Series subwoofers lets
them make tons of bass in small
sealed, vented and bandpass
enclosures. They will also work
well in infinite baffle applications
where there is no space or budget
to build a box. Be aware that infinite baffle or ”free air“ mounting
will reduce the power handling
Thank you for choosing this
JBL Power Series subwoofer. The
Power Series of automotive subwoofers is designed to be used in
modern car audio systems to
produce extended, powerful bass in
a limited amount of space. Power
Series subwoofers are designed to
suit a broad range of applications
and can be used in a wide variety
of enclosure types. In order to
maximize the performance potential of these subwoofers, it is recommended that installation be left
to a qualified professional. If you
feel you have the ability to properly build an enclosure and install
the subwoofer yourself, the information in this manual will help you
get it right.
Keep your sales receipt with this
manual in a safe place so both are
available for future reference.

coating
to dissipate heat and
increase power handling
•
Unique 5-ohm nominal imped-
ance

The JBL Power Series woofers
are designed to maximize the
sonic potential of any system.
When installed in a proper enclosure they offer smooth frequency
response, excellent transient
response, high-output efficiency,
and high-power handling capa-bility. The result is powerful,
dynamic and accurate sound
reproduction that could only
come from JBL.

Enclosure Calculation and
Building
Recommended box designs
are available from your JBL
Dealer, or at www.jbl.com on the
Internet. You may choose cabinet
dimensions to fit your car, but the
internal volume must not be
changed, since changes in internal volume will change the tuning
frequency of the enclosure.
Please contact your authorized
JBL dealer if you cannot do
the necessary calculations yourself. The JBL Speakershop™
dedicated enclosure-design software program may also be helpful
for experienced car-audio
enthusiasts.
Your Car And
The BASS Made In It
Depending on the size of the vehicle, bass frequencies below 50Hz
or 80Hz are actually boosted by
nearly 12dB per octave as the
frequency decreases. If you
wanted to purchase that kind of
power, you would need an amplifier that was eight times more
powerful than the one you have.
You can either reduce bass level
to compensate for this, or simply
sit back and enjoy the “free”
bass.
Sealed enclosures exert the most
control over the motion of a subwoofer because the air acts like a
spring against the motion of the
woofer cone. Larger boxes allow
for more excursion, thus more
sound output for the amount of
power used. When placed in a
sealed box larger than the rated
compliance (Vas) of the subwoofer, it will react as if it were
in an infinite baffle installation.
Vented and bandpass enclosures
have the lowest amount of excursion for the amount of sound output. This is a result of port tuning
reinforcing the sound output.
Vented boxes will not provide
adequate woofer control when
driven below the port tuning
range, meaning proper design is
important. A fourth-order bandpass box will have the lowest
and the low-frequency response
of a subwoofer. Finally, although
information is available for
Bandpass enclosures from your
JBL Dealer, any variations from
the recommended dimensions
should be made using dedicated
enclosure-design software such as
JBL Speakershop™.
If this type of software is not
available, assistance is available
through JBL‘s Web site at
www.jbl.com or from your authorized JBL dealer.

3. All joints should be glued and
screwed; do not use nails.
”Deck“ or ”Zip“ screws are recommended since they have
coarse threads for better grip
and don‘t require pre-drilling
holes. Once the box has been tested, it should be sealed with caulk
around all interior joints.
4. Apply a 1" thick sheet of polyfill (available at fabric and craft
stores) to all inside walls except
the wall where the subwoofer is
mounted. If this is not done,
increase the recommended box
volume by 10 percent.
5. Use PVC or ABS pipe (cardboard tubing is acceptable if the
walls are over 1/16" thick). Keep
in mind the openings at either
end of the port must be at least
one port diameter away from any
obstructions inside or outside of
the box. Minimum recommended
port size is as follows:
8" Subwoofer – 2"
10" Subwoofer – 3"
12" Subwoofer – 3"
15" Subwoofer – 4"
Tools you will need:
• Straight-edge
• Saw (circular or table)
• Screwdriver (powered or
screwdriver bits in a variablespeed drill are best)
• Sabre saw or keyhole saw
(to cut hole for woofer)
• Measuring tape
• Soldering iron and solder
• Wire cutters/strippers
• Utility knife (to cut carpet)
• Pencil
Materials:
• 3/4" or thicker MDF
• Caulk
• PVC or ABS pipe
• Deck screws
• Carpet
• Carpet Adhesive
(aerosol-type works well)
• Speaker wire (12 or 16 gauge
for woofers)
Take your time and mark the
wood carefully before making
any cuts. The old adage ”measure twice and cut once“ definitely
applies here. Use the straightedge to make sure your lines are
straight, and clamp it to the wood
to use it for guiding the saw if
you are using a circular saw.
This will get you the straightest
edges, the best fit and the best
sound.
overall cone excursion at the
expense of limited bandwidth.
1. Dimensions: Whenever possible, try not to make a box that
has dimensions that are equal to,
or multiples of, each other. For
example, a 10" x 10" x 20" box
would be susceptible to standing
waves that may cancel some frequencies and add to cabinet resonance. A better alternative would
be 18" x 11" x 10".
2. It is recommended that 3/4"
(19mm) MDF be used to build the
enclosure. Particle board is
acceptable, but it is more difficult
to work with. Enclosures for 12"
and larger subwoofers, or small
subwoofers, driven by high power
amplifiers should be constructed
out of 1" (25mm) material.

Possible Perils Pertaining
To Power Handling
The power-handling capability of
any woofer is related to both its
ability to dissipate heat, and the
maximum excursion limits of its
cone. Power handling for subwoofers is directly related to the
type of enclosure that is chosen.
The JBL Power Series subwoofers are designed to meet
their power ratings in properly
designed, sealed, vented, and
bandpass boxes. Please be aware
of the following:
• Voice-coil overheating and
burning is typically caused by
overdriving an amplifier into
”clipping“. This damages more
speakers than any other cause.
Damage occurs because the
amplifier is too small rather than
too large. Bass that sounds broken up and distorted at higher
volumes usually indicates that
the amplifier is being asked to
deliver power beyond its
capabilities.
• Sharp ”popping“ sounds coming
from a woofer indicate that the
voice coil is ”bottoming out“ or
hitting the back of the motor
structure. This can seriously
damage a woofer. Either your
sealed box is too big or leaking
air, the port tuning frequency of
a vented box is too high or your
amp may be overpowering the
woofer. Fix the box, retune the
box or turn the gain down on the
amplifier respectively.
• Infinite Baffle or ”free air“
mounting applications allow for
greater cone excursion than subwoofers mounted in an enclosure.
In order to compensate, the
power rating of the subwoofer
should be reduced to half its
rated power. If the woofer
”pops,” turn down the amplifier
gain.
5 Ohms And System
Optimization
In order to increase flexibility,
the Power Series subwoofers are
designed with a 5-ohm nominal
impedance. This provides an
extra margin of safety for simple
installations, and allows those in
competition or those who are
always pushing the ”edge“ to use
more woofers per amplifier channel safely and efficiently, without
shutting the amplifier down or
exceeding the amplifier‘s SOA
(Safe Operating Area), which
could cause serious damage. In
systems using multiple woofers
per channel, please make sure
your amplifier can drive lowimpedance loads safely and
effectively.
