And Polk certifies this sub for marine applications, so they're a great choice for your boat too.

To drive this subwoofer, we recommend a mono subwoofer amplifier that can put out between 200 and 400 watts RMS at 4 ohms. For more information please refer to our article on How to Match Subwoofers and Amplifiers.

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 fire-retardant 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.

Klippel Laser Analyzed: The Polk db woofer's voice coil alignment, motor, and suspension are optimized using a state-of-the-art Klippel laser analyzer for superior cone travel linearity, resulting in a flatter response with lower distortion.

Break-In Period: Polk db subwoofers will achieve even greater performance once they are thoroughly broken-in. To break in a new db Sub, play music through it for 20 to 30 hours at moderate levels.

Enclosure Compatibility

Recommended Sealed Box Volume: Polk recommends mounting this woofer in a sealed enclosure made out of 3/4" MDF with an internal volume of 0.66 cu/ft.

Recommended Ported Box Volume: Polk recommends a ported enclosure made out of 3/4" MDF with an internal volume of 1.25 cu/ft using a 4" diameter x 12" long port.

Recommended Bandpass Box Volume: Polk recommends a bandpass enclosure made of 3/4" MDF with a total internal volume of 1.65 cu/ft. The bandpass box should have a 0.80 cu/ft sealed rear chamber and a 0.85 cu/ft ported front chamber with 4" diameter x 9" long port.

Q
What is the driver volume spec on this sub and is .66 for enclosure with or without that spec ?
[ Saul  Sep 11, 2014 ]
2 answers
A
The specs that they have on their website are a minimum allowed by the manufacturer. So .66 cubic feet would be a minimum allowed for that speaker. And to answer your question, yes, the .66 already includes the speaker displacement. If I were you, I'd make the box, or get a box that has closer to .75 cubic feet of air space inside.
