Polk Audio dX12-4 Car Subwoofer
Polk Audio Updated: 2008-11-15 RSSIt's the biggest, baddest, most bass-happy Polk dX Subwoofer, optimized to deliver explosive bass performance in small sealed enclosures (less than 1 cubic foot). Deep, tight, musical bass -- just what you expect from Polk Audio!
dX Subwoofers feature:
* Polymer and graphite composite cones -- the stiffest cones in the autosound industry! Able to withstand the enormous pressures generated inside small enclosures without breakup and distortion.
* High mass cones allow awesome low frequency tuning in small enclosures.
* Thick ABS dustcaps prevent the distortion that can be caused by the build up of air pressure behind the cap.
* High durometer rubber surrounds provide a much tighter and more durable air seal behind the cone than foam, paper, or cloth surrounds; for deep, tight, quick bass. Also, rubber surrounds don't dry rot like the foam surrounds used by other manufacturers.
* Extra long, precision wrapped and vented coils for superior cooling and high power handling.
* Four layer, 2" voice coil handles the heat generated when your amp is really cranking.
* Vented pole piece lets air circulate over the voice coil to keep it cool and in control even when the bass is really thumping.
* 8 Ohm and 4 Ohm versions available: Choose the impedance that suits your personal system design, including exotic isobaric and push-pull types.
If you're serious about your car stereo -- don't bother with cheap-o speakers. Go for the gusto of the dX Series Loudspeakers. They give you the ultimate in performance, flexibility, and control. They contain some amazing technology -- the kind that makes them tough enough to take the heat, and powerful and efficient enough to inspire many a road trip.
