Thank you  
for choosing an Infinity Kappa Series subwoofer.  
Kappa 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 performance, we strongly recommend that  
installation be left to a qualified professional. Although these instructions  
explain how to install a Kappa Series subwoofer in a general sense, they  
do not show box-construction details and exact installation methods for  
your particular vehicle. If you do not feel you have 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.

POWER-HANDLING LIMITATIONS  
SPECIFICATIONS  
The power-handling capability of any woofer  
is related to both its ability to dissipate heat and  
the maximum excursion limits of its cone. Once  
the speakers voice coil moves outside the mag-  
netic gap, power can no longer be converted into  
motion and all the amplifiers power is converted  
into heat in the voice coil.This voice-coil heating  
is the largest detriment to speaker longevity, so  
overexcursion should be avoided. Since speaker-  
cone excursion is different for each type of  
enclosure, power handling is different for each  
enclosure.  
Sealed enclosures exert the most control over  
the motion of a subwoofer because the air inside  
the box acts like a spring against the motion of  
the woofer cone. Larger boxes allow for more  
excursion, thus providing more low-frequency  
output for the amount of power used. When  
placed in a sealed box larger than the Vas of the  
subwoofer, it will perform as if it were in an  
infinite-baffle installation.  
Vented and bandpass enclosures have the  
lowest amount of excursion for the amount of  
sound output.This is a result of port output rein-  
forcing the sound output from the woofer.The  
mass of the air contained in the port provides an  
acoustic load on the woofers cone at the tuning  
frequency, and this added mass decreases  
woofer-cone excursion. Vented boxes do not pro-  
vide adequate woofer control when driven below  
the port-tuning range, so proper design is impor-  
tant. A vented bandpass box will have the lowest  
overall cone excursion provided a subsonic filter  
is used.

overexcursion are often caused by overdriving an  
amplifier into “clipping.” A severely clipped  
signal, or squarewave, contains nearly twice the  
power of a clean sine wave at the same level. Bass  
that sounds broken up and distorted at higher  
volumes is usually indicative of an amplifier that  
is clipping and being asked to deliver power  
beyond its rated power.

to compensate, recognize that the power-rating

Study the excursion curves on the enclosed  
Cut-out Diameter:  
Kappa Series data sheet and note the differences  
for different enclosure applications.The type and  
size of box used will produce different excursion  
demands on the enclosed subwoofer and, conse-  
quently, different levels of power handling. As  
long as recommended parameters are used, the  
subwoofer will perform properly in its enclosed  
environment. However, any design deviation may  
result in less than optimum performance, and  
may also subject the subwoofer to overexcursion  
(i.e., where the voice coil leaves the gap) that can  
eventually damage the speaker. For additional  
help with this issue, please contact your autho-  
rized Infinity dealer.
