The db1240DVC gives you the power handling and the wiring options to configure your sub setup to realize maximum bass for your mobile audio install. Plus the db1240DVC has all the Polk features that make this 12-inch sub one of the best at low-down performance.

db1240DVC Features:

Polypropylene cone with rigid ABS dustcap to stiffen 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. 

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.

Double 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 - db1240

Optional db12G 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.
