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.
