12" 2Ω Dual Voice Coil Subwoofer

Unleash relentless bass performance with the Diamond Audio HXP122 HEX PRO Series 12-inch dual voice coil subwoofer (2Ω), engineered for high-output car audio systems that demand extreme power, precision control, and long-term durability. As part of Diamond Audio’s flagship HEX PRO lineup, this 12" subwoofer delivers competition-grade output with refined musical accuracy.

At the core of the HXP122 12-inch subwoofer is Diamond Audio’s patented TDX™ (Thermal Dyne Extreme) Technology, integrating the motor structure directly into a rigid cast aluminum frame. This advanced design maximizes heat dissipation, allowing the subwoofer to perform at high SPL levels for extended periods while reducing power compression and increasing reliability.

With 900W RMS and 1800W MAX power handling, this high-performance car subwoofer is built to move serious air. Its oversized 3.5-inch high-temperature voice coil and ultra-high energy neodymium motor structure provide exceptional efficiency, output, and control. Combined with nearly 3 inches of linear excursion, the HXP122 produces deep, hard-hitting bass with outstanding clarity and precision.

The proprietary composite hex cone, reinforced with a NBR surround and dual progressive poly-aramid spiders, ensures superior strength and linear cone movement under extreme conditions. Integrated radial venting and a vented pole piece further enhance cooling and consistent performance.

The dual 2-ohm voice coil configuration allows flexible wiring options and improved amplifier efficiency, making it ideal for custom high-output builds and competition-level systems.
