SELECTABLE IMPEDANCE
This provides easy configuration of
the voice coils. With Kappa subwoofers,
there are no more confusing series and
parallel connections of voice coils,
and the connection of separate woofers
in multisubwoofer systems is easier.
NEODYMIUM MOTOR WITH
ALUMINUM HEATSINK
An aluminum extrusion provides a heatsink
for the motor’s steel parts. Neodymium
provides more magnetic energy in a smaller
space, which reduces overall weight, and is
inherently magnetically shielded.
THREE-INCH-DIAMETER
VOICE COILS
provide plenty of heat-dissipating surface
area for high power handling. Many other
woofers at comparable prices use smaller,
2-inch coils. Kappa woofers handle more power.
VENTED POLEPIECE
reduces air compression under the dust
cap, minimizing mechanical noise, and
provides more constant mechanical Q for
reduced distortion.
MEDIUM Q DESIGN
provides great performance in sealed,
vented or band-pass enclosures. Sealed
enclosures for Kappa woofers can be ±30
percent of the recommended volume.
Optimum vented boxes do not require
superlong ports.
TESTED TO ENSURE
THEY’LL STAND UP
Infinity subwoofers are tested according
to the strictest and most demanding
reliability-testing regimen ever designed
for car audio speakers. They are shaken,
baked, frozen and dropped, all while they’re
operating, and attempts are even made to
destroy them with signals up to 10 times their
rated power. When they’ve passed those tests,
the subs are subjected to their RMS and peak
power limits for 100 hours. Many competing
subs are tested for only eight hours.
EXTRACT ALL THE POWER
FROM ANY AMPLIFIER
Kappa Series subwoofers are available in
two configurations that provide either a
2-ohm or 8-ohm impedance, or 1-ohm or
4-ohm impedance. That’s enough flexibility
to provide an optimum load to any amplifier.
