FBT X-SUB 118SA Description

The FBT X-SUB 118SA is engineered for powerful low-frequency reinforcement in professional sound systems. Its 18" high-excursion woofer, paired with a 3" voice coil, is driven by a 1200W Class D amplifier with an integrated universal switching power supply for worldwide voltage compatibility. The result is deep, controlled bass performance ideal for a wide range of live and installed applications. Onboard DSP provides four user-selectable presets, allowing you to tailor the sub’s response to different environments or speaker pairings. The stereo XLR input and output configuration includes hi-pass outputs for satellite tops, and a 0°/180° phase switch ensures optimal alignment with other system components. Built into a rugged 18mm birch plywood enclosure with a scratch-resistant coating, the X-SUB 118SA is designed to withstand the rigors of touring while maintaining sleek aesthetics for permanent installs. Dual aluminum side handles, optional 100mm wheels, and an integrated M20 pole mount add to the system’s flexibility and ease of use.
