Polk has done all the work for you. All you do is mount and wire in the db1212 enclosure and turn up the bass. All the Polk technology that makes it a db subwoofer is here, plus the attention to detail that create the legendary Polk reliabiity.

db1212 Features:

High power handling 360 Watts continuous and 720 Watts peak.

Side vented slot port provides thunderous bass and allows greater air displacement then round port designs while keeping the enclosure slim.

Extensively braced trapezoidal MDF enclosure eliminates performance-robbing box flex.

Nickel plated heavy duty input terminals accommodate speaker wire up to 8 AWG or twisted pairs of 12 AWG.

Viscoelastic isolation damping between the baffle and cabinet prevent any unwanted vibrations or buzzes when the subwoofer is driven hard.

Rugged automotive grade black carpet provides an attractive and durable enclosure finish.

Heavy duty automotive grade ABS grille provides awesome looks but also protection for the woofer.

Paintable grille and baffle look great as is, or may be matched to your vehicle’s color.

2 ohm impedance maximizes amplifier power.
