Overview - Rockville W10K5S4 Subwoofer: The W10K5S4 from Rockville's K5 Series is a 10" single 4-Ohm voice coil subwoofer engineered for high output and reliability. Power handling includes 1200 Watts peak, 600 Watts program, and a CEA rated RMS of 300 Watts. Motor & Voice Coil: This woofer uses a 2" 4-layer black aluminum voice coil wound with OFC (100% Copper) wire. The voice coil wire is imported from Japan for superior quality. The magnetic assembly features a 40 Oz high-quality magnet and a high BL magnetic motor gap. A vented hole on the T-yoke improves heat dissipation. Basket & Cone: Constructed with a cast iron basket finished in black sanded paint, the driver uses a fiber reinforced ultra-stiff black non-pressed paper cone for efficient output. The paper dust cap is lightweight to aid output even with modest amplification. Surround, Reinforcement & Durability: A thick foam surround minimizes distortion while providing robust excursion. Blue stitching reinforces the cone for long-term durability. Chrome-plated binding post terminals accept any gauge wire. Rubber boot magnet covers protect and enhance the woofer's appearance. Rockville-branded mounting gasket helps achieve an air-tight installation. Thermals & Adhesives: The woofer is assembled using a highest-grade black glue rated for extremely high temperatures to help the driver handle power reliably.
