Overview: The Polk Audio DXi112 is a single enclosure, loaded with a
12" DXi subwoofer.
Enclosure Design: The enclosure is made of heavy duty 3/4" MDF
(medium-density fiberboard), internally braced for strength and to eliminate
resonance. The enclosure is covered with high quality, automotive-grade black carpet.
Front Baffle: Instead of a grille, the DXi112 has a heavy duty front
baffle to protect the woofer. The baffle is made of rigid, automotive-grade ABS,
which can be painted to match your vehicle's styling. In front of the baffle is
an Elastomeric damping material to isolate the ABS trim from the baffle, and to
act as a gasket to seal the woofer.
PowerPort: The enclosure's internal PowerPort venting with a
slot-loaded port reduces air turbulence at the mouth of the port. This design
provides high bass output and less noise and distortion than conventional
Driver: The DXi112 is loaded with a single 12" DXi subwoofer. The
polypropylene woofer cone is stiff for quick-responding, punchy bass. It is
built to withstand the demanding automotive environment. The woofer's Santoprene
surround can withstand humidity, extreme temperatures, and long exposures to sunlight
to give you years of performance.
2-ohm Rating: The woofer is rated at 2 ohms to bring out the best
performance from high quality Class D subwoofer amplifiers.
Note: You should make sure your amplifier can operate safely at
very low impedances before bridging the amp to a 2-ohm load.
Woofer Design: The DXi112's woofer is designed using a
state-of-the-art Klippel laser analyzer. The perfect alignment of the voice
coil, motor structure, and suspension provides optimum performance with low
distortion and a flatter response. The high-temperature, 4-layer voice coil is
well ventilated for better power handling. The speaker's flat Nomex spider
allows extended linear motion for higher output and better reliability.
Preconditioning Period: The DXi112's performance will achieve optimum
performance after a short break-in period. It is recommended to play the DXi112
at moderate levels for 20 to 30 hours to reach the highest level of performance.
