CLUB SUBWOOFERS

WS1000 and WS1200

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.

S E PEALED- NCLOSURE ERFORMANCE

ADVANTAGES

• 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.

S E PEALED- NCLOSURE ERFORMANCE

TRADE-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.

S E CEALED- NCLOSURE 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.

T JBL RHE 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.

S EEALED 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
