HXP124 -HEX Pro 12" 4 Ω Dual Voice Coil Subwoofer

 The HXP124 HEX PRO Series 12-inch subwoofer from Diamond Audio is engineered for enthusiasts and professionals who demand uncompromising bass performance, extreme durability, and precision sound control. Built as part of Diamond Audio’s flagship HEX PRO lineup, the HXP124 delivers competition-level output with advanced thermal management and musical accuracy.

At the core of the HXP124 is Diamond Audio’s patented TDX™ (Thermal Dyne Extreme) Technology, where the motor structure is seamlessly integrated into a rigid cast aluminum frame. This innovative design maximizes heat dissipation, allowing the subwoofer to play louder for longer at high SPL levels while reducing power compression and extending component life.

Featuring nearly 3 inches of linear excursion, the HEX PRO Series subwoofers are capable of producing massive low-frequency output while maintaining tight control and clarity. This high-excursion design enables deeper bass extension and a broader low-frequency range, delivering bass that is both aggressive and musical.

With a dual 4-ohm voice coil configuration for flexible wiring options, the HXP124 is ideal for high-performance car audio systems seeking extreme bass, reliability, and long-term performance. Experience bass engineered to dominate.
