Go ahead, circle the parking lot till your favorite song is over. The bass from this DXi 112 loaded enclosure will make you want to hit "repeat" so you can hear it all over again. Polk uses a high-tech approach and ideal materials to give your tunes an exciting new edge.

Exacting standards — precise engineering where it counts
The enclosure houses a DXi Series 12" sub with a stiff polypropylene cone and Santoprene rubber surround, so you can ride the bass wave for years to come. Engineers at Polk analyze drivers in motion to ensure that cone movement is even and precise, so you'll get impressive thump with minimal distortion. Polk also uses laser imaging to craft woofer cones that are perfectly balanced to resist distortion-causing resonances.

Sturdy housing for your bass beats
The enclosure features advanced internal bracing that reduces distortion-causing resonances so you'll get nice, clean bass. Specially engineered slot ports limit air turbulence and let your sub play louder and stronger when you're in the mood. Pair it with the right amp and wiring, then strap yourself in for a serious low-frequency ride.

Features

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 tube-style ports.

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.

Specifications:

  • Frequency Response: 26 Hz - 200 Hz
  • Power Handling (RMS): 360 watts
  • Power Handling (Peak): 720 watts
  • Efficiency: 100dB
