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.
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 Deep-draw I-beam Basket:
The deep-draw I-beam design allows room for a longer motor structure, which
provides increased bass output. This basket is also more rigid and has a lower
Vented Polepiece: The vented
polepiece provides additional cooling of the motor structure. The subwoofer's
thermal capabilities are augmented, 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.
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.
