Choosing an Enclosure

Decade Series subwoofers are optimized

to perform best in small sealed, vented

and prefabricated bandpass enclosures.

While innite-bae mounting of Decade

Series subs is possible, power handling

will be greatly compromised since there

will be no enclosed volume of air to

prevent the speaker ’s cone from mount-

ing past its limit. For this reason, we do

not recommend innite-bae mounting

for Decade Series subwoofers.

You should choose the enclosure you will

use based on the type of music you listen

to, how much amplier power you will

use for the subwoofer, and how much

space inside the vehicle you can devote

to a subwoofer enclosure.

Because a sealed enclosure provides the

most control over the woofer ’s move-

ment, a woofer mounted in a sealed

enclosure will handle more power than a

woofer mounted in a dierent kind of

enclosure. Sealed enclosures provide

more accurate sonic reproduction than

other enclosure types, so they are well-

suited to all types of music. Sealed enclo-

sure construction is straightforward, and

there are many prefabricated sealed

enclosures available. An optimum sealed

enclosure is always smaller than other

types of enclosures optimized for a par-

ticular speaker, so they require the small-

est amount of space inside the vehicle.

Vented enclosures provide better

eciency in the 40Hz – 50Hz range, but

this eciency comes at the expense of

sound in the lowest octave (below 40Hz)

and at the expense of some control and

power handling. If you are using a small

amplier, a vented box will provide more

bass output from less power. Vented

enclosures are also well-suited to a

variety of music types. Because vented

enclosures require the volume of the

enclosure and the size of the port to have

a specic relationship with the character-

istics of the woofer, the enclosure must

be built exactly to the specications pro-

vided. While there are some prefabricated

vented boxes available, matching a

prefabricated vented box to a particular

woofer is dicult. If you wish to use a

vented enclosure, we strongly recom-

mend having your authorized JBL dealer

build it, or verify that your design is cor-

rect if you wish to build it yourself. An

optimum vented enclosure is always

larger than the optimum sealed box for

the same woofer, and will require more

space inside the vehicle.

Bandpass enclosures often provide the

greatest output available from any ampli -

er and subwoofer combination at the

expense of sonic accuracy. If sheer SPL

(sound-pressure level) is what you desire

most, choose a bandpass enclosure.

Bandpass enclosure design is very tricky

and the aid of a computer and enclosure-

design software is essential. If you are an

experienced installer or have some wood-

working experience, you may wish to

build the enclosure described in the

Specications chart in this manual.

Fortunately, there are many prefabricated

bandpass boxes available, and they are

all optimized to extract the greatest out-

put possible from any woofer. Bandpass

enclosures can be quite large, and may

require a lot of space inside your vehicle.

Thank you for purchasing a new JBL

Decade™ Series subwoofer. Subwoofer

installation often requires woodworking

skills and some experience disassembling

and reassembling automotive interiors. If

you lack the tools or skills necessary,

have your subwoofer installed by an

authorized JBLdealer.

Warning: Playing loud music in an auto -

mobile can permanently damage your

hearing as well as hinder your ability to

hear trac. We recommend listening at

low levels while in your car. JBL accepts

no liability for hearing loss, bodily injury

or property damage resulting from use or

misuse of this product.
