  • (1) Hot Sale Sundown Audio Sml 12" 500w Rms Dual 2 Ohm Subwoofer Sml-12-d2 Tool [5GZXaecv]


The Sundown Audio SML 12" Subwoofer is designed to deliver impressive performance in a compact and durable package. With a 500W RMS power rating, this subwoofer provides deep, responsive bass while maintaining efficiency and control. Its bolt-through motor design ensures maximum longevity, eliminating visible bolts on the back for a sleek look. The black aluminum 2.5" voice coil former enhances heat dissipation, while the high-temperature 4-layer copper voice coil ensures reliable performance under heavy loads. Engineered with a dual-magnet design, vented pole-piece, and multi-vented magnetic gap, the SML-12-D2 is built for optimal airflow and cooling. Whether you're upgrading your daily driver or building a high-performance audio system, this subwoofer offers exceptional sound quality, durability, and low-distortion bass reproduction.


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