Built using advanced technology inspired by the flagship HEX PRO lineup, this 12" subwoofer delivers powerful, musical bass with exceptional control.

At the core of the H124 HEX 12-inch subwoofer is a massive 3-inch high-temperature dual voice coil, wound on a reinforced aluminum former to ensure consistent performance under heavy power loads. With 600W RMS and 1200W MAX power handling, this car audio subwoofer produces deep, punchy bass while maintaining clarity and low distortion.

This advanced cooling system effectively dissipates heat, reducing power compression and allowing for extended high-performance listening sessions.

The fiber weave cone, reinforced with a treated paper backing, delivers fast transient response and excellent rigidity. This results in tight, accurate bass reproduction with impressive low-frequency extension, making it ideal for both daily listening and high-output builds.
