• (1) Sundown Audio SML 10″ 500W RMS Dual 4 Ohm Subwoofer SML-10-D4

The Sundown Audio SML 10″ Subwoofer is built for powerful and reliable bass performance in a compact design. With a 500W RMS power rating, this subwoofer delivers deep, controlled low frequencies while maintaining efficiency and durability. Its bolt-through motor design eliminates visible bolts for a clean, seamless look, while the black aluminum 2.5″ voice coil former enhances heat dissipation for long-lasting performance. The high-temperature 4-layer copper voice coil ensures stability under demanding conditions, and the dual-magnet design, vented pole-piece, and multi-vented magnetic gap optimize airflow for improved cooling. Engineered with precision, the SML-10-D4 produces low-distortion bass with a custom-tooled cone shape that reduces mechanical noise during high excursion. Whether you’re upgrading your car audio system or building a high-performance setup, this subwoofer is designed to deliver exceptional sound quality and durability.

** This motor is bolted through the top so the bolts are not visible from the back like several other models.
