The FBT ProMaxX 15SA is a 1200W RMS active subwoofer with a 15" woofer in a band-pass design.

It can be used to extend the low frequency response to a wide range of FBT speaker systems for applications such as live stage, theater, houses of worship, DJ setups, clubs, and more.

The ProMaxX 15SA has several other features such as a frequency response of 38 to 120 Hz and a 1200W class D power amplifier that uses a switch mode power supply. The built-in digital signal processor has 8 presets, 2 equalization and 4 LPF crossover settings, to allow the sub to be configured with any speaker.

The 15 mm birch-plywood enclosure for the ProMaxX 15SA, which has an anti-scratch paint finish, features a control-panel that has XLR input and link output jacks; in addition, a volume control, EQ presets, delay, a 0 to 180° phase switch, and a ground-lift switch located on the rear panel. Also built into the enclosure are 2 aluminum integrated carry handles and a M20 stand adapter to mount a two-way speaker (sold separately). Power is supplied using the included AC power cable.
