The dB Technologies FIFTY 118S Active 18" Subwoofer is a powerful partner for the Fifty Top, rounding out dB Technologies’ scalable Fifty Line PA system. Built on the same DSP and Class-D amplification platform as the Fifty Top, it provides strong low-frequency performance down to 38 Hz in a compact, tour-ready enclosure.
A single 18" driver with a 10.2 cm voice coil, combined with 1600 W RMS / 3200 W peak amplification, delivers up to 135.4 dB SPL. The recommended stacked configuration is 1–2 Fifty Tops over 2 Fifty Subs, creating a flexible system for medium-to-large live events and fixed installations.
