What’s included: 1x Rockville W12K6D4 V2 12" car subwoofer and 1x Rockville RSV12 single 12" vented subwoofer enclosure (1.22 cu.ft., 3/4" MDF). Also included are 10 drywall wood screws (note: ‘wood screws’ refers to the screw type; the screws are metal), 12 feet of 14 AWG blue speaker wire, and 2 spade terminals. Power & motor specs: Peak power handling of 2400 Watts, program power 1200 Watts, and CEA rated RMS of 600 Watts. The motor uses a double-stacked 100 Oz high-quality magnet and an air-tight high BL magnetic motor gap. Vented hole on the T-yoke improves heat dissipation. Voice coil & wiring: 2.5" 4-layer black aluminum voice coils wound with OFC (100% copper) wire — the wire is made in the USA. XMAX is 22 MM (one way). Impedance: dual 4-Ohm voice coils. Cone, surround & basket: Fiber-reinforced ultra-stiff black non-pressed paper cone with a polypropylene (PP) dustcap. Thick foam surround and red stitching cone reinforcement provide long life and reduced distortion. The basket is cast aluminum with a black sanded finish for improved efficiency. Terminals & protection: Two chrome-plated binding post terminals accept any gauge wire. Special custom rubber boot magnet covers protect the magnet and enhance appearance. Includes a custom Rockville mounting gasket for an easier, airtight install. We use a high-grade black adhesive that resists very high temperatures to help the woofer handle greater power than its rating. Physical & acoustic specs: Sensitivity is 85dB.
