2 Rockford Fosgate Prime R2SD4-12 prime stage 500W Max (250W RMS) 12" shallow mount dual 4-ohm voice coils subwoofer

When you have no space for bass, our Prime R2SD4-12 shallow subwoofer will satisfy your needs. This 12” subwoofer handles 250 Watts RMS, and the 4-Ohm Dual Voice Coil design lets you wire them in various configurations. 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.
