Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Features
High-efficiency Polypropylene
Woofer Cone: This lightweight and popular material is used to ensure maximum
woofer efficiency. The benefit is high output with modest amplifier power.
Large-roll Rubber Surround: The
large-roll rubber surround provides optimum cone-edge suspension and absorbs
distortion that may travel up the cone edge, ensuring clean, tight bass.
Proprietary Basket: The unique
in-board motor structure reduces the overall mounting depth, without limiting
enclosure options.
Vented Polepiece: The vented
polepiece provides additional cooling of the motor structure, thus increasing power handling.
Progressive Spider: The
subwoofer uses a progressive spider, which provides better control at excursion
limits than more commonly used linear spiders. The result is reduced distortion
at high output levels.
Enclosure Compatibility
Sealed Box
Volume: Infinity recommends a sealed enclosure with an internal volume
of 0.75 cu/ft. Sealed enclosures provide the most control over a woofer, will
handle more power, and provide more accurate sonic reproduction, making them
suitable to all types of music.
Ported Box
Volume: Infinity recommends a ported enclosure with an internal volume
of 1.75 cu/ft with one 3" diameter x 4.75" long port. Ported (or vented)
enclosures provide better efficiency in the 40-50Hz range, and are suitable for
use with small amplifiers, giving you more bass output from less power. However,
this efficiency comes at the expense of sound quality at low frequencies (40Hz
and below), and control.
Bandpass Box Volume: Infinity recommends a bandpass enclosure
with an internal volume of 2.0 cu/ft. The enclosure has a sealed chamber volume
of 1.0 cu/ft and a ported chamber volume of 1.0 cu/ft with one 4" diameter x
7.875" long port. Bandpass enclosures often provide the most output
available from any amplifier and subwoofer combination at the expense of sonic
accuracy. If sheer SPL is desired most, a bandpass enclosure is recommended.
