Incredible Sound, Affordable Price

The compact db840DVC comes with all the Polk goodies that make this a great entry level mobile audio subwoofer for installs on land or sea. And because its a dual voice coil configuration, you have lots of wiring options for matching your amplifier’s capabilities.

db840DVC Features:

“Dish” polypropylene cone supported by a vented cone/coil coupler stiffens the cone for greater mechanical stability and lower distortion.

Marine Certified Polk db Series speakers are built tough to withstand the toughest environments so they are perfect for use in boats of all types. That’s why Correct Craft offers Polk speakers in their award-winning Nautiques ski and wakeboarding boats.

Santoprene surround is impervious to extremes in temperature, humidity and exposure to sunlight for excellent long term reliability.

Fire-retardant flat NOMEX® spider allows extended linear motion while providing highly reliable mechanical and thermal stability.

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.

As with all Polk subwoofers, the voice coil alignment, motor and suspension were optimized using a state-of-the-art Klippel laser analyzer. The result is superior cone travel linearity for flatter response and lower distortion.

Single voice coil version also available - db840

Optional db8G grille is available.

All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry’s most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk  loudspeakers are built to perform for a lifetime.
