15" 4Ω Dual Voice Coil Subwoofer

Command the low end with authority using the Diamond Audio HXP154 HEX PRO Series 15-inch dual voice coil subwoofer (4Ω), engineered for extreme SPL performance, precision bass control, and uncompromising durability. Built for serious car audio enthusiasts and competition-level systems, this 15" subwoofer delivers massive output with refined musical accuracy.

At the core of the HXP154 15-inch subwoofer is Diamond Audio’s patented TDX™ (Thermal Dyne Extreme) Technology, seamlessly integrating the motor structure into a rugged cast aluminum frame. This advanced design maximizes heat dissipation, allowing the subwoofer to maintain peak performance during extended high-output sessions while reducing power compression and enhancing long-term reliability.

With an impressive 1100W RMS and 2200W MAX power handling, this high-performance car subwoofer is built to push serious air. Its massive 4-inch high-temperature voice coil and ultra-high energy neodymium motor structure provide exceptional efficiency, control, and output. Combined with nearly 3 inches of linear excursion, the HXP154 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 performance consistency.

The dual 4-ohm voice coil configuration offers flexible wiring options, allowing configurations down to 2Ω or up to 8Ω, making it ideal for custom amplifier matching in high-output builds.
