The db212-2 enclosure features:

  • Internally braced 3/4-inch MDF--the same low resonance material used in the world's finest speaker enclosures.
  • The front baffle is clad in automotive grade ABS trim for rigidity and resistance to impact.
  • A sheet of Elastomeric damping material isolates the ABS trim from the baffle as it acts as a sealing gasket for the woofers. This "trilaminate" sandwich construction prevents unwanted rattles and resonance, ensuring bass that's as tight as it is powerful.
  • Polk Audio's patented Power Port venting technology reduces air turbulence at the port mouth for higher bass output with vastly lower noise and distortion compared to conventional ports.
  • Wheel-style heavy-duty ABS grilles protect the drivers from shifting cargo. Grilles and baffle may be painted to match the vehicle's interior color.

The dual db124 12-inch subwoofers feature:

  • Single Voice Coil 4 Ohm drivers wired in parallel for a net 2-Ohm load, optimum for today's Class D subwoofer amplifiers.
  • Stiff Polypropylene cones for outstanding temperature and tensile strength.
  • Santoprene surrounds stand-up the harshest automotive environments, including extremes in temperature, humidity and exposure to sunlight for excellent long term reliability.
  • Fire-retardant flat NOMEX Spiders allow extended linear motion while providing highly reliable mechanical and thermal stability.
  • Former and pole piece vent the 4-Layer High Temperature Voice Coil Fomer for exceptional power handling and reliability.
  • Voice coil alignment, motor and suspension were optimized using a state-of-the-art Klippel laser analyzer, ensuring superior cone travel linearity for flatter response and lower distortion.
