12" 4Ω Dual Voice Coil Subwoofer

Experience commanding bass performance with the Diamond Audio HXP124 HEX PRO Series 12-inch dual voice coil subwoofer (4Ω), engineered for competition-level car audio systems that demand extreme output, precision control, and long-term reliability. As part of Diamond Audio’s flagship HEX PRO lineup, this 12" subwoofer delivers powerful, musical low frequencies with advanced engineering built to dominate.

At the core of the HXP124 12-inch subwoofer is Diamond Audio’s patented TDX™ (Thermal Dyne Extreme) Technology, which integrates the motor structure directly into a rugged cast aluminum frame. This innovative design significantly improves heat dissipation, allowing the subwoofer to perform at high SPL levels for extended periods while reducing power compression and enhancing durability.

With an impressive 900W RMS and 1800W MAX power handling, this high-performance car subwoofer is built to handle serious power. Its oversized 3.5-inch high-temperature voice coil combined with an ultra-high energy neodymium motor structure delivers exceptional efficiency, output, and control. Featuring nearly 3 inches of linear excursion, the HXP124 moves massive air, producing deep, hard-hitting bass with remarkable clarity.

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

The dual 4-ohm voice coil configuration offers flexible wiring options, making it ideal for custom amplifier setups and high-output builds.
