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.
Curvilinear Aluminum Cone: The
curvilinear aluminum cone is lightweight and extremely
rigid for low distortion and superior bass response.
High-roll Butyl Surround:
The high-roll butyl surround damps cone resonance and ensures longevity.
The non-resonant cast aluminum basket ensures perfect alignment of the speaker's
Spider: The spider design
provides maximum control over cone motion at the limits of the speaker's
excursion, and reduces even-order harmonic distortion compared to cupped
Vented Pole Piece:
A flared, polished and vented pole piece is used to provide optimum cooling of
the voice coil and minimize turbulence.

Recommended Sealed Box
Volume: Infinity recommends a sealed enclosure with an internal volume
of 1.0 cu/ft.
Box Volume: Infinity recommends a ported enclosure with an internal
volume of 1.75 cu/ft. One 4" diameter x 12.33" long port should be
used with a 1.75 cu/ft enclosure.
Recommended Sealed Bandpass Box
Volume: Infinity recommends a bandpass enclosure with an internal
volume of 3.45 cu/ft. The 3.4 cu/ft enclosure should have a sealed chamber
volume of 2.2 cu/ft and a ported chamber volume of 1.25 cu/ft. One 4"
diameter x 10.7" long port should be used in the ported chamber.
addition to being compatible with sealed, ported and bandpass enclosures, the
woofer can be used in free-air applications. A free-air subwoofer is
designed to be mounted on a baffle board, which separates two areas of the
vehicle. For instance, you could mount this woofer to a board
attached to the rear deck or placed in the trunk against the rear seat. The
trunk acts as the enclosure housing the subwoofer.
