Got enough juice? Get an amp for your new sub Get the power and precision you want from your subwoofer, with the reliability that comes from a name you trust! Polk's db (Dynamic Balance) series subwoofers are engineered with state-of-the-art technologies, combining the best materials so you get top-notch performance and clean, smooth bass.

The Polk db104 10" subwoofer features a polypropylene cone, shaped like a dish for extra rigidity. The cone is encircled by a tough Santoprene rubber surround that shrugs off the harmful effects of exposure to sun, moisture, and extreme temperature changes — this sub will stand the test of time! The Kapton voice coil former is triple-vented so the sub stays cool when the bass gets hot. And you don't have to limit these speakers to your car — they've passed tough environmental testing that certifies them for marine use as well.

Specification Note

Features

Polypropylene Cone: The cone is made with polypropylene, which provides durability while being lightweight and rigid. The cone is supported by a vented cone/coil coupler, which stiffens the cone for greater mechanical stability and lower distortion.

Santoprene Surround: The Santoprene surround is resistant to extremes in temperature, humidity, and exposure to sunlight for excellent long term reliability.

NOMEX Spider: The flat NOMEX Spider allows extended linear motion while providing highly reliable mechanical and thermal stability.

Triple-vented Kapton Voice Coil Former: Triple venting of the 4-layer Kapton Voice Coil Former, Cone/Coil Coupler and Pole Piece contribute to the high power handling and reliability of the db Series subs.

Marine Certified: Polk db Series speakers are built to withstand exposure to moisture and UV rays, so they work well in boats and cars.

Enclosure Compatibility

Recommended Sealed Box Volume: Polk recommends using this woofer in a sealed enclosure with an internal volume of 0.66 cu/ft.

Recommended Ported Box Volume: Polk recommends a ported enclosure with an internal volume of 1.25 cu/ft. One 4" diameter x 12" long port should be used with a 1.25 cu/ft enclosure.

Specification Note

Power Handling: Per Polk, the label on the woofer magnet incorrectly lists a continuous power handling of 225 watts RMS, and a peak power handling of 450 watts. The manual and box correctly list a continuous power handling of 270 watts RMS, and a peak power handling of 540 watts.
