Overview: The Polk Audio DXi108 is a single enclosure, loaded
with a single 8" 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 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.
Port: The enclosure is vented with a slot-loaded port to reduce
air turbulence (and noise) at the mouth of the port.
Driver: The DXi108 is loaded with a single 8" 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.
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 with a 2 ohm load.
Woofer Design: The DXi108'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.
Terminal: The nickel-plated spring post terminal will accept
pin connectors, single banana plugs, and bare wire up to 10-gauge.
Preconditioning Period: The DXi108 will achieve optimum
performance after a short break-in period. It is recommended to play the DXi108
at moderate levels for 20 to 30 hours to reach the highest level of performance.
