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.
Cone Design: The woofer uses a rigid sisal fiber cone with
a durable rubber surround. The mechanical advantages of sisal, rigidity and inner
damping, result in faster transients and precise detail.
Cast Aluminum Basket: The die-cast aluminum basket resists
flexing and resonance (ringing).
Terminals: The woofer features a pair of spring post terminals.
They accept pin connectors or bare wire up to 10-gauge.
Sealed Box: Although designed for a ported enclosure, the P8W
subwoofer can also be used in a sealed enclosure. The optimum internal volume is
0.28 cubic foot. Sealed enclosures provide the most control over a woofer, will
handle a lot of power, and provide accurate sonic reproduction, making them suitable
to all types of music.
Ported Box: The recommended ported box has an internal volume
of 0.48 cubic feet with a 3" diameter x 5" long port tube, giving a tuning
frequency of 80 Hz and a -3dB point of 68 Hz. Ported (or vented) enclosures typically
provide better overall efficiency than sealed so they are suitable for use with smaller
amplifiers, giving you more bass output from less power.
Bandpass Box: When using a bandpass enclosure, the sealed rear
chamber should be 0.58 cubic feet and the ported front chamber should be 0.26 cubic
feet with a 2-3/4" diameter x 5-2/3" long port.
