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.
Design: This woofer has a
five-sided polypropylene cone. This design stiffens the cone, resulting in lower
distortion and higher power handling.
Foamed Rubber Surround: The
foamed rubber surround provides high power handling, enhanced cone control and
flexibility. "Hash Marks" in the surround provide added stability.
P5 Center Cap: The five-sided
dust cap adds strength to the cone assembly.
Inner Cap: The inner cap at the
top of the voice coil former stabilizes the former's "roundness" and
strengthens the connection between the cone and the former.
Three-layer woven dampers provide enhanced cone control and have the lead wires
woven in to prevent shorting to the frame.
Voice Coil: The
four-layer, edge-wound voice coil provides plenty of copper to pass the current
necessary for high power reliability.
Binding Posts: The gold-plated
binding posts will accept bare wire, pin connectors, spade lugs and banana
plugs. The binding posts are spaced too far apart to accept dual banana plugs.
Enclosure Compatibility: This
woofer can provide extended bass in sealed and ported enclosures (please see the
