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.
The cone is constructed of Polypropylene, giving you lower distortion and a
natural resistance to moisture.
The hi-roll rubber surround offers
superior cone edge suspension and rejects moisture and UV rays. Additionally,
the hi-roll design allows for greater excursion, resulting in deeper bass
Progressive Spider: The progressive spider
offers better control at excursion limits than a linear spider, giving you more
Dual-Stacked Magnets: The dual-stacked
magnet assembly increases efficiency.
Vented Pole Piece: The
vented pole piece allows air to circulate in the voice coil gap; air circulating
in the voice coil gap helps dissipate heat and results in greater power handling
and increased reliability.
Back Plate: The back plate has been stepped
deeper to allow the woofer more room for excursion without bottoming out.
Gold-Plated Binding Posts:
The gold-plated binding posts will accept bare wire, pin connectors, spade
connectors, or banana plugs. Since the binding posts will not accept dual banana
plugs, they are not 5-way.
This woofer can provide extended bass in sealed, vented and
bandpass enclosures. It is
designed to work best in a sealed enclosure with an internal volume of 0.75
cu/ft, or a ported enclosure with an internal volume of 1.75 cu/ft (port
diameter: 3", port length: 9.01", port tuning frequency: 28 Hz). The
recommended bandpass enclosure has a sealed chamber volume of 1.00 cu/ft, and a
ported chamber volume of 1.00 cu/ft (port diameter: 4", port length:
7.87", port tuning frequency: 50 Hz).
