The FBT X-SUB 115SA is a professional active 15" bass reflex subwoofer designed to add powerful low-frequency reinforcement to portable and installed sound systems. Built around a 15" woofer with a 3" voice coil and a 1200W Class D amplifier, it provides strong bass performance in a compact cabinet format suitable for mobile DJs, live sound users, venues, schools, houses of worship, hospitality spaces, AV installers and event production companies. As part of FBT’s X-SUB range, the X-SUB 115SA is designed to work as a low-frequency extension for active loudspeaker systems, including FBT X-LITE and X-PRO series speakers. This makes it a strong choice for users who need additional bass impact for music playback, live vocals, DJ sets, presentations, fitness spaces, small stages, function rooms and general sound reinforcement. FBT specifically describes the X-SUB range as designed as the perfect partner for the X-LITE and X-PRO series. The subwoofer uses a bass reflex cabinet design to deliver efficient low-frequency output from a manageable enclosure. Its frequency response is listed at 42Hz to 120Hz at -6dB, giving it useful extension for kick drum, bass guitar, electronic music, DJ playback and full-range programme audio. With a maximum SPL of 135dB half-space, the X-SUB 115SA provides substantial output for a compact 15" active subwoofer. Power is delivered by an integrated 1200W Class D amplifier. This powered format removes the need for a separate amplifier rack, helping simplify system setup and reducing the amount of additional equipment required. For portable users, this means faster deployment and fewer components to transport. For fixed installations, it provides a matched amplifier and loudspeaker solution that is straightforward to specify and integrate. The onboard DSP processor includes 4 presets, giving users practical control over the subwoofer’s response for different applications and speaker pairings. FBT lists the presets as 2 responses with 2 different cut-off frequencies, allowing the subwoofer to be adapted to suit different system layouts. This is useful when pairing the X-SUB 115SA with different top speakers or using it across multiple room types and event formats. The control panel provides stereo combo XLR/jack inputs and outputs, stereo XLR high-pass filter outputs, level control, preset selection, 0°/180° phase reversal and protection/limiter LED indicators. These controls make the subwoofer practical for professional PA systems, allowing signal to be routed cleanly to full-range speakers while giving the operator essential tools for level matching, phase alignment and basic system optimisation. The X-SUB 115SA is built from 15mm birch plywood with a scratch-resistant black painted finish. This gives the cabinet the durability required for portable audio work, live events and fixed installations where equipment needs to withstand regular handling. The cabinet also includes two aluminium handles, helping users lift and position the subwoofer during setup and pack-down. Optional 100mm transport wheels are available for users who need improved mobility. An M20 top-mounted stand adapter is included, allowing a compatible full-range speaker to be pole-mounted above the subwoofer. This supports a clean sub-and-top system layout for mobile DJs, schools, bars, churches, small venues and hire systems. When paired with suitable active top speakers, the X-SUB 115SA can form the low-frequency foundation of a compact but professional PA system. The subwoofer measures 455 x 584 x 570mm and weighs 30.3kg. Transport dimensions are listed as 710 x 650 x 600mm, with a transport weight of 36.5kg. These figures are important for users planning storage, van loading, venue access and manual handling. For customers looking to add controlled low-frequency output to an active PA system, the FBT X-SUB 115SA offers a strong balance of power, portability and professional build quality. With a 15" driver, 1200W Class D amplifier, 135dB SPL, DSP presets, XLR signal routing, birch plywood construction and M20 pole mount, it is a practical subwoofer for portable sound, venue installations and AV systems requiring reliable bass reinforcement.
