Enjoy your music even more

Go ahead, circle the parking lot till your favorite song is over. The bass from this DXi1201 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 create a sub that'll add serious impact to your tunes.

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 resonances so you'll get nice, clean bass. The enclosure's 2-ohm impedance draws maximum power from a mono amp. Specially engineered slot ports limit air turbulence and help your sub play louder and stronger when you're in the mood to turn it up. Pair it with a good amp and wiring, then strap yourself in for a serious low-frequency ride.

Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

Features

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 carpet.

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 performance.

Specifications:

  • Frequency Response: 20-300 Hz
  • Power Handling (RMS): 360 watts
  • Power Handling (Peak): 720 watts
  • Efficiency: 88dB
