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.
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
basket design delivers a decrease in mounting depth while maximizing woofer
Vented Polepiece: The vented
polepiece provides additional cooling of the motor structure. The subwoofer's
thermal capabilities are augmented, 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.
Gold-plated Binding Posts: The
gold-plated binding posts will accept pin connectors, spade connectors, banana
plugs, and bare wire.
Note: The binding posts
are positioned too far apart to accept dual banana plugs.
