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 Honeycomb cone membrane coated
with fiberglass. The rubber surround is resistant to UV rays for added durability.
Dual 2-ohm Voice Coils: This woofer features dual 2-ohm voice
coils, offering wiring flexibility. When the voice coils are wired in parallel the
woofer presents a 1-ohm load. When the voice coils are wired in series the woofer
presents a 4-ohm load.
Cast Aluminum Basket: The die-cast aluminum basket resists
flexing and resonance (ringing).
Terminals: The woofer features two pair of spring
post terminals. They accept pin connectors or bare wire up to 10-gauge.
Sealed Box: For the best sound quality when you're short on
space, use a sealed enclosure; the optimum internal volume is 0.9 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 1.75 cubic feet with a 4" diameter x 12" long port tube, giving a
tuning frequency of 38 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.
