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

V EENTED NCLOSURES

A vented enclosure acts like a sealed

enclosure at frequencies above its tuned

(resonance) frequency. At resonance

(which is defined by the vent), the vent

produces the majority of sound – the

subwoofer cone is nearly stationary while

the air inside the vent vibrates. This

provides greater mechanical power

handling at and above resonance, but

reduced mechanical power handling below

resonance. Since the subwoofer cone and

voice coil don’t move much at resonance,

airflow across the voice coil is minimized

and thermal power handling is reduced

slightly at resonance.

Vented enclosures provide better

efficiency in the 40Hz – 60Hz range, at

the expense of sound output in the lowest

octave (below 40Hz). The use of an

infrasonic filter is recommended with

vented enclosures. An optimum vented

enclosure for a Club Series subwoofer is

larger than an optimum sealed enclosure.

See accompanying data sheet for specific

enclosure dimension requirements.

V E PENTED- NCLOSURE ERFORMANCE

ADVANTAGES

• An optimum vented enclosure has

greater efficiency and higher output in

the 40Hz – 60Hz range than an optimum

sealed enclosure.

• An optimum vented enclosure provides a

greater sensation of bass than an

optimum sealed enclosure.

• A Club WS1000 or WS1200 subwoofer in

an optimum vented enclosure will

require less amplifier power to achieve

a given acoustic output (down to the

enclosure’s resonance frequency) than

in an optimum sealed enclosure.

B -P EAND ASS NCLOSURES

Band-pass enclosures can provide the

most output from any amplifier and

subwoofer combination over a limited

band of frequencies, but that additional

output comes at the expense of sonic

accuracy. Band-pass enclosures combine

a sealed or vented enclosure that houses

the subwoofer along with a vented

chamber into which the subwoofer

outputs its sound. The vented chamber

acts as an acoustic low-pass filter which

attenuates high frequencies in the

subwoofer’s output. That attenuation of

high frequencies can make it very

difficult to hear amplifier and speaker

distortion; consequently, you may not be

able to determine when the subwoofer is

in danger of being damaged.

See accompanying data sheet for specific

enclosure dimension requirements.

B P E PAND- ASS- NCLOSURE ERFORMANCE

ADVANTAGES

• An optimum band-pass enclosure

provides higher output over a limited

bandwidth than an optimum enclosure of

any other type.

B P E PAND- ASS- NCLOSURE ERFORMANCE

TRADE-OFFS

• Band-pass enclosures achieve high

output at the expense of sonic

accuracy.

• An optimum band-pass enclosure has a

more limited bandwidth than an

optimum enclosure of any other type.

• The enclosure’s low-pass filter

characteristics can make it difficult to

hear if the subwoofer is in danger of

being damaged.

• An optimum band-pass enclosure is

usually larger than an optimum vented

enclosure.

B P E CAND- ASS- NCLOSURE ONSTRUCTION

Band-pass-enclosure construction is more

difficult than vented-box construction

and, as with vented enclosures, the

design parameters for the vented section

must be followed carefully. (The sealed

section is more forgiving of small design

and construction variations.) Fortunately,

there are many prefabricated band-pass

enclosures that are designed to extract

the most output possible from nearly any

subwoofer. Prefabricated band-pass

enclosures are strongly recommended if

you must have a band-pass enclosure. If

you choose to build your own band-pass

enclosure, use medium-density fiberboard

(MDF), glue and screws to construct the

enclosure,and be sure to seal all joints

with silicone caulk.

T JBL RHE ECOMMENDATION

Band-pass enclosures are recommended

only for enthusiasts who want high

sound-pressure levels (SPL) without

regard for sonic accuracy. If high SPL

AND great-sounding bass are your goals,

choosing a vented enclosure is

recommended instead.

V EENTED- NCLOSURE PERFORMANCE

TRADE-OFFS

• Reduced output in the lowest octave

(below 40Hz).

• Reduced mechanical power handling

below the enclosure’s resonance

frequency. The use of an electronic

infrasonic filter is strongly recommend-

ed, to reduce the chance of overdriving

the subwoofer below the enclosure’s

resonance frequency.

• An optimum vented enclosure will

always be larger than an optimum

sealed enclosure.

V E CENTED- NCLOSURE ONSTRUCTION

Vented-enclosure construction is more

difficult than the construction of a sealed

enclosure. The enclosure volume and port

dimensions have a specific relationship

with the physical and electromechanical

characteristics of the subwoofer,

requiring that the recommended

enclosure volume and port characteris-

tics be strictly observed. As with sealed

enclosures, 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

vented enclosures are recommended for

enthusiasts who prefer accentuated bass

response, for those who have plenty of

cargo space to devote to a subwoofer

enclosure and for those who will use a

less powerful amplifier to drive their

subwoofer. The volume and port

dimensions indicated on the included

technical data sheet must be followed

precisely to ensure optimum

performance.
