No one’s music is really all there without a dedicated subwoofer to add the thump that gives a performance its raw, in-your-face feeling. If you’re serious about your music, you want to take a serious look at our subwoofers for filling out the low notes. And Polk subwoofers are styled to make an install a real contender on the show circuit. All at a price that’s hard to beat.

db1222 Dual 12” Sub Enclosure

Dual 12-inch driver high performance sub enclosure

We’d like to say we won’t bore with the details. But sometimes making a sub better is all about the details. Such is the case with our dual 12-inch sub enclosures. We took what we knew worked from our db212, did a little refining to make this next generation more impressive, then added even more blow-you-away performance. The result is just plain nasty. Which is good.

Front loaded slot port provides thunderous bass and allows greater air displacement then round port designs.

Extensively braced trapezoidal MDF enclosure eliminates performance-robbing box flex. dB1222 is 32-inches W x 14-inches H x 15-inches D at the top and 18-inches D at the bottom and weighs 88 lbs.

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 grilles provide awesome looks but also protection for the woofers.

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

2 ohm impedance uses subwoofer amplifier power most effectively.

Klippel optimized components using a state-of-the-art Klippel distortion analyzer, Polk engineers were able to optimize the woofer’s motor structure, voice coil alignment and suspension for the best possible performance, even at extreme listening levels.

Dynamic Balance® composite woofer cones feature tremendous stiffness-to-mass ratio. Lower mass means faster transients and finer detail.
