THANK YOU

for purchasing a JBL

Grand Touring

Series subwoofer.

Subwoofer installation requires woodworking skills and some

experience in disassembling and reassembling automotive

interiors. If you lack the tools or necessary skills, have your

subwoofer installed by an authorized JBL dealer.

CHOOSING AN ENCLOSURE

WARNING: Playing loud music

in an automobile can permanently

damage your hearing as well as

hinder your ability to hear trafﬁc.

We recommend listening at low

levels while driving. JBL accepts no

liability for hearing loss, bodily injury

or property damage resulting from

use or misuse of this product.

Grand Touring Series subwoofers

are optimized to perform best in

small, sealed, vented and prefabri-

cated band-pass enclosures. While

inﬁnite-bafﬂe mounting of GTO subs

is possible, power handling will

be greatly compromised because

there’s no enclosed volume of air

to prevent the speaker’s cone from

moving past its limit. For this reason,

we do not recommend inﬁnite-bafﬂe

mounting for GTO subwoofers.

You should choose the enclosure

you will use based on the type of

music you listen to, how much

ampliﬁer 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 movement, a woofer

mounted in a sealed enclosure will

handle more power than a woofer

mounted in another enclosure type.

Sealed enclosures provide more

accurate sonic reproduction than

other enclosure types when

mounted inside a vehicle, so they

are well suited to all types of music.

Sealed-enclosure 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 particular speaker, so they

require the smallest amount of

space inside the vehicle.

Vented enclosures provide better

efﬁciency in the 40Hz – 50Hz range,

but this efﬁciency comes at the

expense of sound in the lowest

octave (below 40Hz) and at the

expense of some control and power

handling at the lowest frequencies.

If you are using a small ampliﬁer,

a vented box will provide more

perceived 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 speciﬁc relationship with the

characteristics of the woofer, the

enclosure must be built toexactly

the speciﬁcations provided. While

there are some prefabricated

vented boxes available, matching

a prefabricated box to a particular

woofer is difﬁcult. If you wish to

use a vented enclosure, we strongly

recommend having your authorized

JBL dealer build it or verify that your

design is correct 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.

Band-pass enclosures often provide

the most output available from any

ampliﬁer and subwoofer combination,

at the expense of sonic accuracy.

If sheer SPL (sound-pressure level)

is what you desire most, choose a

band-pass enclosure. Band-pass-

enclosure design is very tricky and

the aid of a computer and enclosure

design software is necessary. If you

are an experienced installer or have

some woodworking experience,

you may wish to build the band-pass

enclosure described in the enclo-

sure design sheet included with this

woofer. Fortunately, there are many

prefabricated band-pass boxes

available and they are all optimized

to extract the most output possible

from any woofer. Band-pass

enclosures can be quite large and

may require a lot of space inside

your vehicle.
