The FBT X SUB 115SA is a powerful active 15" subwoofer in bass reflex design and the ideal addition to professional sound reinforcement systems. With its 1200 W Class D amplifier, a 15" woofer with 3" voice coil and a maximum sound pressure level of 135 dB peak, it delivers powerful, precise and superior bass for live events, clubs, conference rooms, bands and fixed installations.
Thanks to its frequency response of 42 Hz to 120 Hz, the subwoofer provides a convincing low-frequency extension and fits perfectly with the FBT X LITE and X PRO series. The integrated DSP processor with four presets offers flexible customization options for different applications and speaker setups. Two sound characteristics, each with two different crossover frequencies, enable fast and practical tuning.
The X SUB 115SA also impresses in terms of handling and features: the robust housing made of 15 mm birch multiplex with a scratch-resistant black finish is designed for professional use. Two FBT aluminum handles facilitate transport, while the integrated M20 flange enables the secure attachment of a distance rod for tops.
Stereo combo XLR/jack inputs, link outputs and stereo XLR high-pass filter outputs for satellite speakers are available for maximum connection flexibility. In addition, the subwoofer offers 0°/180° phase inversion, a level control, preset switch and PRT/LMT status LEDs for reliable monitoring during operation.
The FBT X SUB 115SA is therefore a strong choice for anyone looking for a compact, robust and powerful active subwoofer for professional sound reinforcement applications.
