Unleash pure, unrelenting bass with the DS18 EXL-TR15.4D—a competition-grade subwoofer engineered for those who crave the deepest, cleanest, and most powerful low-end possible. Built to dominate in both performance and durability, this 15-inch beast is the next evolution in DS18’s legendary EXL line.

Delivering a massive 2500W RMS and 5000W MAX power handling, the EXL-TR15.4D is made for high-output builds that push limits. Its triple-stacked 295oz ferrite magnet motor produces incredible magnetic force, giving you explosive bass response with pinpoint accuracy and thunderous volume.

The EXL-TR15.4D features a curvilinear, non-pressed paper cone reinforced with epoxy coating, ensuring both flexibility and rigidity for distortion-free output at high SPL levels. A 4-inch black aluminum voice coil wound with CCAW material delivers exceptional heat resistance and maintains power flow under heavy load, while crossed spider leads provide consistent motion stability during extreme excursion.

Engineered with precision, this subwoofer achieves a one-way Xmax of 20mm, giving you the dynamic cone movement needed for deep, rolling bass that hits hard and clean. Thanks to DS18’s improved heat dissipation system and vented aluminum basket, the EXL-TR15.4D stays cool no matter how intense the session gets.

Versatility is key — optimized for both sealed (1.25ft³) and ported (2.5ft³ tuned to 30Hz) enclosures, the EXL-TR15.4D adapts seamlessly to your sound preference. Whether you’re after tight, accurate bass or room-shaking resonance, this sub delivers consistent, competition-quality performance.

With its dual 4-ohm voice coils, this subwoofer gives you complete wiring flexibility, while its 6-gauge push terminals make installation simple and secure. From professional SPL setups to high-end daily drivers, the EXL-TR15.4D is the subwoofer that commands respect — both in sound and in strength.

Built to last. Tuned for perfection. Designed to destroy the competition. The DS18 EXL-TR15.4D isn’t just a subwoofer—it’s the bass revolution you’ve been waiting for.
