Designed using advanced technology inspired by the HEX PRO Series, this 15" subwoofer delivers deep, hard-hitting bass with remarkable clarity and consistency.

At the core of the H154 HEX subwoofer is a massive 3-inch high-temperature dual voice coil, wound on a reinforced aluminum former for superior heat resistance and long-term reliability.
