Martin Audio Blackline XP118 | 2000W 18-Inch Active Professional Subwoofer
Extreme low-end authority. The XP118 is a compact, high-output subwoofer that extends the low-frequency response of any PA system down to an impressive 42Hz. At its core is a long-excursion 18-inch driver with a 4-inch voice coil, driven by a 2000W Class-D amplifier. The integrated DSP provides crossover functions and essential system protection, while the rear-panel interface allows for easy adjustment of levels and presets. Encased in a rugged birch-ply cabinet with a large-area port to reduce air noise, the XP118 delivers "the Martin sound"—a signature characterized by warmth, punch, and high-fidelity precision that maintains its character even at a staggering 137dB peak SPL.
