THANKYOU
for choosing an JBL Club
WS1000 or Club WS1200 subwoofer. These
Club subwoofers are designed to suit a
broad range of car audio applications and
can be used in a wide variety of enclosure
types to produce extended, powerful bass
in a limited amount of vehicle space. To
get the most performance from your new
subwoofer, it is strongly recommended
that you have a qualified professional
install your WS1000 or WS1200
subwoofer. Although this manual does
provide general instructions about
installing these Club Series subwoofers, it
does not include enclosure construction
details or exact installation methods for
any particular vehicle. If you do not feel
that you have the necessary experience,
do not attempt the installation yourself,
but instead ask your authorized JBL dealer
about professional installation options.
Remember to keep your sales receipt in a
safe place, along with this manual, so
that both are available for future Club.

WARNING
Playing loud music in a vehicle can hinder
your ability to hear traffic and
permanently damage your hearing. The
maximum volume levels achievable by JBL
speakers when combined with high-power
amplification may exceed safe levels for
extended listening. Using low volume
levels is recommended when driving. JBL
Systems accepts no liability for hearing
loss, bodily injury, or property damage as
a result of use or misuse of this product.
the subwoofer cone. The result is a
stiffer suspension when compared to the
subwoofer operating in free air. This
means that the subwoofer’s cone will be
harder to move at low frequencies, a
condition which protects the subwoofer
from physical overexcursion, but
requires more power than other designs
to achieve a given acoustic output.
See accompanying data sheet for specific
enclosure dimension requirements.

DVANTAGES
• The in-vehicle performance will have
the flattest overall frequency response.
• The in-vehicle response will have the
widest bandwidth. (Usable low-frequency
response inside the vehicle will be
below 20Hz.)
• An optimum sealed enclosure will always
be smaller than an optimum enclosure of
another type.

RADE-OFFS
• An optimum sealed enclosure will have
lower overall efficiency than an
optimum enclosure of another type.
• A Club WS1000 or WS1200 subwoofer in
an optimum sealed enclosure will require
more amplifier power to achieve a given
acoustic output than in an optimum
enclosure of another type.

ONSTRUCTION
Sealed-enclosure construction is straight-
forward and forgiving of errors in volume
calculation, but air leaks should be
avoided. Use medium-density fiberboard
(MDF), glue and screws to construct the
enclosure, and seal all joints with silicone
caulk.

ECOMMENDATION
Club WS1000 and WS1200 subwoofers in
sealed enclosures are recommended for
enthusiasts who prefer accurate music
reproduc-tion and flat frequency
response, for those who have a smaller
space to devote to a subwoofer
enclosure, and for those who have plenty
of amplifier power devoted to driving the
subwoofer. The sealed-enclosure design
indicated on the technical data sheet
accompanying this manual represents the
best compromise between low-frequency
extension and flat response.
REPRODUCING
BASS IN VEHICLES
Depending on the size of your vehicle’s
interior listening space, reproduced bass
frequencies below 80Hz will be boosted
by nearly 12dB per octave as frequency
decreases. This phenomenon, known as
the vehicle’s transfer function (or cabin
gain), plays an important role in shaping
the subwoofer’s frequency response in
your vehicle. The enclosed technical data
sheet includes frequency response graphs
that show both the subwoofer’s “in-car”
response (which factors in this vehicle
transfer function) and its “out-of-car”
response (which does not).
SUBWOOFER
ENCLOSURE TYPES
Club WS1000 and WS1200 subwoofers are
designed to perform best in moderately
sized sealed enclosures, vented
enclosures and prefabricated band-pass
enclosures. Infinite-baffle mounting is
possible, but the subwoofer’s mechanical
power handling will be reduced because
there will be no volume of air to stiffen
the subwoofer’s suspension and prevent
overexcursion. If you choose infinite-baf-
fle mounting, consider the RMS and peak
power-handling ratings to be half of what
is listed in the specifications in this
manual.
You should choose an enclosure type
based on the amount of cargo space you
can devote to the enclosure, the amount
of power you will use to drive your
subwoofer(s), and your listening habits.

NCLOSURES
The air trapped inside a sealed enclosure
is compressed when the subwoofer moves
rearward and is rarefied when the
subwoofer moves forward. In both cases,
the air inside and outside the box will
seek equilibrium by pushing and pulling on
