Set of (2) Rockville W10T4-S4 10\" Shallow Mount 2400 Watt 4-Ohm Car Audio Subwoofers

Overview: Two Rockville W10T4-S4 10" shallow-mount car subwoofers, CEA compliant and built with a single 4-Ohm voice coil. Power Handling (CEA Rating): 1200 Watts Peak Power / 600 Watts Program / 300 Watts RMS. Designed for compact installs, these subs combine high output with a space-saving shallow basket. Driver Construction & Components: Ultra-stiff paper composite cone with a 3D molded high-gloss acrylic dust cap. The frame is an ultra-slim, expanded and rolled steel basket. Suspension uses a high-density laminated butyl rubber surround. Motor and thermal components include a high-power strontium magnet with an ultra-saturated, high BL motor gap, a vented core magnet motor structure, and a high-temperature aluminum voice coil former. Magnet protection is provided by a rubber band and connection is via dual nickel-plated spring-loaded push terminals. Mechanical & Acoustic Specs: Impedance: SVC 4 Ohm. Cutout Diameter: 9.1 Inches.
