THANK YOU for choosing
an Infinity@ Reference Series subwoofer.
Reference Series 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 ensure maximum
subwoofer performance, it is strongly
recommended 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
that 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 that both are
available for future reference,
WARNING
Playing loud music in an automobile can per-
manently damage your hearing, as well as
hinder your ability to hear traffic. The maxi-
mum volume levels achievable with Infinity
speakers, combined with high power amplifi-
cation, may exceed safe levels for extended
listening. Using low volume levels when dri-
ving is recommended. Infinity Systems
accepts no liability for hearing loss, bodily
injury or property damage as
a result of use or misuse of this product.
YOUR CAR
AND BASS
REPRODUCTION
Depending on the size of the vehicle's
interior listening space, reproduced bass fre-
quencies below 80Hz are boosted by nearly
12dB per octave as frequency decreases in
the car. NOTE: This effect, known as the vehi-
cle'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,
CHOOSINGAN
ENCLOSURE
Reference Series subwoofers are optimized
to perform best in small sealed, vented and
prefabricated band-pass 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 speak-
er's cone from moving past its limit. For this
reason, infinite-baffle mounting
is not recommended 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 straightforward 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 efficiency
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 vent-
ed enclosure, it is strongly recom-mended
that you have 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,
