The FBT SUBLine 18SA is a bass-reflex active powered speaker featuring a 1200W RMS woofer and an 18" woofer. It can be utilised to extend the low frequency response of a wide range of FBT speaker systems for live stage, theatre, houses of worship, DJ settings, clubs, and other applications.
A frequency response of 33 to 140 Hz and a 1200W class D power amplifier with a switch mode power supply are among the additional features of the SUBLine 18SA. To allow the sub to be customised with any speaker, the built-in digital signal processor offers 6 presets, 3 equalisation, and 2 LPF crossover settings.
The SUBLine 18SA is housed in a 15 mm birch-plywood enclosure with an anti-scratch paint finish that includes a control panel with dual XLR/jack inputs/outputs, as well as a volume control, EQ settings, a 0 to 180° phase switch, and an LED status indicator on the back panel. Two aluminium integrated carry handles are also included, as well as an M20 stand adapter for mounting a two-way speaker (sold separately). The accompanying AC power cable is used to provide electricity.
