It boasts an impressive 2000W RMS and 4000W MAX power handling, ensuring an earth-shattering bass performance that can be felt as much as heard. At its core, the EXL-TRX12.4D features a robust triple-stacked 255oz ferrite magnet motor, providing substantial magnetic force for superior cone control and distortion-free bass.

The subwoofer's construction includes a reinforced non-pressed paper cone with an epoxy coating for added strength and responsiveness, a high-roll foam surround for enhanced excursion, and a crossed spider lead system to stabilize cone movement during extreme SPL conditions. With a wide frequency response ranging from 10Hz to 500Hz, this subwoofer is capable of reproducing the deepest bass notes with authority. The dual 4-ohm voice coil configuration offers significant wiring flexibility, allowing users to optimize performance based on their specific amplifier setup. The EXL-TRX12.4D is designed for versatility and performs exceptionally well in both sealed enclosures (recommended 0.6ft³) and ported enclosures (recommended 1.5ft³ tuned at 30Hz), enabling customization to suit individual audio preferences. It is built for those who demand a powerful low-end rumble that commands attention.
