Inspired by the advanced HEX PRO platform, this 12" subwoofer delivers powerful, musical bass with exceptional control and reliability.

At the heart of the H122 12-inch subwoofer is a massive 3-inch high-temperature dual voice coil, built on a treated aluminum former for superior strength and heat resistance. With 600W RMS and 1200W MAX power handling, this high-performance car subwoofer produces tight, impactful bass while maintaining clarity at high output levels.
