THANK YOU for choosing an Infinity Reference

Series subwoofer. Reference Series subwoofers

are designed to suit a broad range of mobile-

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 ensure maximum subwoofer perfor-

mance, we strongly recommend that installation

be left to a qualified professional. Although these

instructions explain how to install a Reference

Series subwoofer in a general sense, they do not

show box-construction details or exact installation

methods for your particular vehicle. If you do not

feel you have the necessary experience, do not

attempt the installation yourself, but instead ask

your authorized Infinity dealer about professional

installation options.

Remember to keep your sales receipt with this

manual in a safe place so both are available for

future reference.

WARNING: Playing loud music in an automobile

can permanently damage your hearing, as well as

hinder your ability to hear traffic. The maximum

volume levels achievable with Infinity speakers,

combined with high power amplification, may

exceed safe levels for extended listening. We

recommend using low volume levels when

driving. Infinity accepts no liability for hearing

loss, bodily injury or property damage as a result

of use or misuse of this product.

Y COUR AR AND BASS REPRODUCTION

Depending on the size of the vehicle’s interior lis-

tening space, reproduced bass frequencies below

80Hz are boosted by nearly 12dB per octave as

frequency decreases in the car. NOTE: This effect,

known as the vehicle’s transfer function, plays

an important part in shaping the overall in-car

response and is displayed graphically along with

freespace response on the enclosed data sheet

for your Reference subwoofer.

CHOOSING AN ENCLOSURE

Reference Series subwoofers are optimized

to perform best in small sealed, vented and

prefabricated bandpass enclosures. While

infinite-baffle mounting of Reference Series

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

Reference Series 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, so they are well suited to all types of

music. Sealed-enclosure construction is straight-

forward and there are many prefabricated sealed

enclosures available. Optimum sealed enclosures

are 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 ef– ficiency 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

amplifier, 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

specific relationship with the characteristics of the

woofer, the enclosure must be built exactly to 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

Infinity 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.

Bandpass 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 bandpass

enclosure. Bandpass-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 enclosure

described in the enclosure design sheet included

with this woofer. Fortunately, there are many

prefabricated bandpass boxes available and

they are all optimized to extract the most output

possible from any woofer. Bandpass enclosures

can be quite large and may require a lot of space

inside your vehicle.
