Constructed from 15 millimetre birch plywood with a durable black paint finish, the cabinet includes an M20 stand adapter, dual aluminium handles designed by FBT, and compatibility with optional 100 millimetre transport wheels. The control panel features stereo combo XLR and jack inputs and outputs, stereo high-pass XLR outputs, level adjustment, a preset selector, phase inversion switch, and LED indicators for protection and limiting. The FBT X SUB 115SA is built for reliable, high-performance use in professional sound reinforcement applications.
