Kenwood KFC-W3016PS, Performance Series 12" Single 4 Ohm Voice Coil Car Subwoofer, 2000W

Sound Technology Low frequency output has been improved by increasing the cone area without changing the cutout diameter. By adopting a "Stress-free Spider" and a "Thermal Efficient System" the mechanical and thermal durability has also been improved dramatically delivering smooth and strong bass. Square Array Pattern By using a polypropylene woofer cone with a "Square Array" pattern, cone strength is increased and low frequency performance is enhanced.
