Cone: The KFC-W3013PS uses a polypropylene cone and rubber
surround for added durability.
Heat Transfer System: A dual ventilation system design
helps keep the motor structure cool, improving power handling and longevity.
Long Stroke Design: The pole piece has been extended to
provide a more linear magnetic field for woofer operation. This lowers distortion
and provides the woofer with better low frequency response.
Double Stacked Magnet: The stacked magnet assembly is used
to create a powerful linear motor with increased excursion capability for superior
Spring Terminals: The spring post terminals on one side of the
woofer connect to your amplifier's wiring. The posts will accept pin connectors,
single banana plugs, or bare wire up to 10 gauge.
Sealed Box: Kenwood recommends a sealed enclosure with an
optimum internal volume of 1.25 cubic feet (from 0.75 to 1.75 cubic feet is
acceptable). 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: Kenwood recommends a ported enclosure with an
internal volume of 2.0 cubic foot (from 1.5 to 2.5 cubic feet is acceptable)
using an 12-3/4" x 1-1/2" x 21-1/2" slot port. 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. However, this efficiency comes at the expense of very low frequency output.
