The FBT X-SUB 118SA provides low-frequency reinforcement for mobile DJs, live bands and installed PA systems. Designed to complement FBT X-LITE and X-PRO speakers, it combines an 18-inch woofer and 3-inch voice coil with a built-in 1200W Class-D amplifier.

Its bass-reflex enclosure delivers a frequency response of 38Hz–120Hz at -6dB, with a maximum peak SPL of 136dB in half-space conditions. This makes it a practical choice for adding weight to kick drums, bass instruments and dance music playback.

Four DSP presets help tailor the bass response to your system, alongside level adjustment and a 0°/180° phase switch. Stereo inputs, link outputs and high-pass filtered outputs provide flexible routing to active main speakers or external amplifiers.

Built from 18mm birch plywood, the cabinet has a scratch-resistant black finish for regular use in venues and on the road. Two aluminium handles assist handling, while the M20 top mount accepts a compatible speaker pole. Optional 100mm wheels can be fitted for easier transport.
