FBT MITUS 118FSA Active Subwoofer
FBT MITUS 118FSA is a flyable 18-inch active subwoofer with an integrated amplifier and DSP.
It extends the low-frequency range of systems built around MITUS 206LA line-array modules. The FSA version faces forward; FBT specifies a separate FSCA version for the rear-facing element of a cardioid arrangement.
The enclosure contains one B&C neodymium 18-inch woofer with a 3.5-inch voice coil. A 1200 W RMS Class D amplifier and eight DSP presets support flown and ground-stacked configurations.
The rear panel provides XLR input and link, level, preset, delay and phase controls, plus a ground-lift switch. Its integrated suspension hardware works with the MITUS 206LA rigging system.
Main Features
- The 18-inch neodymium woofer with a 3.5-inch voice coil covers 33–100 Hz at the -6 dB point.
- The built-in 1200 W RMS amplifier removes the need for a separate power amplifier.
- Eight DSP presets address flown, ground-stacked and cardioid configurations.
- Rigging compatibility with MITUS 206LA supports a combined subwoofer and full-range array.
- XLR input and link connections carry the signal onward to additional system modules.
- Phase, delay and level controls help align the subwoofer with the other array elements.
- The 15 mm birch-plywood cabinet has a scratch-resistant black finish suited to repeated transport.
