dB Technologies FIFTY 118S – Active 18″ Subwoofer

The dB Technologies FIFTY 118S (Fifty Sub) is a mighty companion to the Fifty Top, completing dB Technologies’ scalable Fifty Line PA system. Sharing the same DSP and Class-D amplification topology as the Fifty Top, it delivers solid low-frequency reproduction down to 38 Hz in a compact, road-ready cabinet.

A single 18″ driver with 4″ voice coil paired with 1600W RMS / 3200W Peak amplification produces up to 135.4 dB SPL. Ideal stacked configuration is 1-2 Fifty Tops over 2 Fifty Subs – a versatile rig for medium-to-large live events and installs.
