TH AN K YOU for choosing an
Infinity'" Kappa'" Series 100,9w or 120.9w
subwoofer, These Kappa subwoofers are
design~d 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 100,9w
or 120,9w subwoofer, Although this manual
does provide general instructions about
installing these Kappa 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 Infinity 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 reference,

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 Infinity speakers when
combined with high-power amplification
may exceed safe levels for extended
listening, Using low volume levels is
recommended when driving. Infinity
Systems accepts no liability for hearing
loss, bodily injury, or property damage as
a result of use or misuse of this product,
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),

VENTED ENCLOSURES
A vented enclosure acts like a sealed
enclosure at frequencies above its tuned
(resonance) frequency, At resonance (which
is defined by the venn, 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 ot
sound output in the lowest octClve (below
40HZ), The use of an infrasonic filter is
recommended with vented enclosures,

Sr,e ClccompClnying datCl sheet for specific
enclosure dimension requirements,
VENTED-ENCLOSURE PERFORMANCE ADVANTAGES
• An optimum vented enclosnre 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 100,9w or 120.9w subwoofer in an
optimum vented enclosure will require
less amplifier power to achieve a given
acoustic output (down to the enclosure's
resonClllce frequency) than in an optimum
serlled enclosure.
VENTED' ENCLOSURE 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 recommended,
to reduce the chance of overdriving
the subwoofer below the enclosure's
resonance frequency,
• An optimum vented enclosure will
Cllways be larger than an optimum
sealed enclosure.
VENT ED- ENCLOSURE CONSTRUCTION
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 characteristics he 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,
THE INFINITY RECOMMENDATION
100,9w and 120.9w 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.

~-,
BAND-PASS ENCLOSURES
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,
BAND-PASS-ENCLDSURE PERFORMANCE
ADVANTAGES
• An optimum band-pass enclosure provirles
higher output over a limited bandwidth
than an optimum enclosure of any other
type.
BAND-PASS-ENCLOSURE PERFORMANCE TRADE-Om
• Band-pass enclosures achieve high output
at the expense of sonic accuracy,
• An optimum band-pass enclosure has a
more limited bandwidth than an optimulll
enclosure of any other type.
• The enclosure's 10W-IJaSS filter character-
istics 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,
BAND-PASS-ENCLOSURE CONSTRUCTION
Band-pass-enclosure construction is more
difficult than vented-box construction and,
as with vented enclosures, the design
parameters for the vented section must
IJe followed carefully, (The sealed section
is more forgiving of small design 3nd
construction variations.) Fortunately,
there are many prefabricated hand-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 hand-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\Jlnnnity
THE INFINITY RECOMMENDATION
Band-pass enclosures are recommended
only tor 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.

MOUNTING THE
SUBWOOFER
The 100,9w and 120,9w subwoofers can be
mounted from the outside of the enclosure
or from the inside of the enclosure, Which-
ever way you mount the subwoofer, use the
included foam mounting gasket to ensure a
leak-free seal between the subwoofer
frame and the enclosure,
CONNECTING THE
SUBWOOFER
SETTING THE IMPEDANCE
The 100,9w and 120,9w subwoofers both
feature the Selectable Smart Impedance'·
(SSI) switch, This exclusive feature lets
you set the subwoofer's impedance to
either 2 ohms or 4 ohms with the flip of
a switch (see illustrations to the right),
This allows you to extract the most from
your subwoofer amplifier in any situation,
2-0hm Setting
4-0hm Setting
The SSI 2-ohm setting increases the
subwoofer's output over the 4-ohm setting
by up to 3dB, depending on the amplifier,
Performance is identical in all other
respects, If the connected amplifier is
rated for 2-ohm operation and its 2-ohm
power ratings are within the subwoofer's
power-handling specifications, setting the
SSI switch in the 2-ohm position will
achieve maximum output,
IMPORTANT: Make sure the
subwoofer amplifier is turned OFF before
setting the SSI switch, Do not change
the switch position while the subwoofer
amplifier is operating. Doing so could
damage the amplifier,

CONNECTING THE AMPLIFIER
The Kappa 100.9w and 120.9w subwoofer
connectors are compatible with bare wire
up to 8 AWG (tinned or untinned) and wire
that is terminated with pin connectors.
Although single banana connectors will fit
into the connector openings, the connection
may not be secure.
