Car Audio Fanatics who want Rockford Fosgate quality can rely on the Prime Series 12" subwoofers to get the job done, and the Dual Voice Coil provides awesome installation flexibility. These drivers can pump out the bass due to their mica injected polypropylene cone, and their stamp-cast baskets with spider venting - typically reserved for more expensive models - keep the motor running cool! These R2 subwoofers are optimized for sealed and vented enclosures.
