The Rockford Fosgate R2SD2-12 2 Ohm 12 Inch Slim Subwoofer with Dual Voice Coils is perfect when needing major power in a small form factor for your bass! These drivers can fit in tight spaces due to an elevated motor structure that reduces speaker depth. Mica injected polypropylene cones make sure bass notes are clean and accurate. Stamp-cast baskets feature spider venting typically reserved for traditional depth mounted models to keep the motor cool! These shallow subwoofers are optimized for sealed enclosures.
