Overview: The Polk Audio DXi1201 is a ported 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
Front Baffle: Instead of a grille, the DXi1201 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.
Driver: The DXi1201 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
rubber surround can withstand humidity, extreme temperatures, and long exposures
to sunlight to give you years of performance.
2Ω Rating: The woofer is wired to present a 2Ω load.
Klippel Optimized: For a driver to reproduce complex sounds
accurately, the cone must move exactly the same distance and manner in both
directions. The Klippel distortion analyzer, a device that uses a laser and
sophisticated software to do large-scale analysis of drivers in motion, lets
Polk optimize the speaker's motor structure, voice coil alignment, and suspension
to yield the best possible performance.
Preconditioning Period: The DXi1201's performance will achieve
optimum performance after a short break-in period. It is recommended to play the
DXi1201 at moderate levels for 20 to 30 hours to reach the highest level of
- Frequency Response: 20-300 Hz
- Power Handling (RMS): 360 watts
- Power Handling (Peak): 720 watts
