FBT Audio X-SUB 115SA 15-Inch Active Powered Subwoofer
The FBT Audio X-SUB 115SA is a professional 15-inch active powered subwoofer designed to add deep, powerful low-frequency performance to portable PA systems, DJ setups, live sound rigs, venues and fixed installations.
Featuring a 15-inch / 380 mm high-excursion woofer, 1200W Class D internal amplifier and bass-reflex cabinet design, the X-SUB 115SA is the ideal low-frequency companion for the FBT X-LITE and FBT X-PRO speaker ranges. It delivers a frequency response of 42Hz - 120Hz @ -6dB and a maximum SPL of 135dB peak, making it suitable for DJs, bands, venues, event production and professional PA applications.
Powerful 15-Inch Bass Performance
The X-SUB 115SA uses a 15-inch high-excursion woofer to deliver strong, controlled bass for music playback, DJ systems and live performance. It provides the low-end extension needed to give PA systems more depth, punch and impact.
1200W Class D Amplification
A built-in 1200W Class D amplifier provides efficient, high-output power while keeping the system practical for portable and installed use. This gives the subwoofer the headroom needed for demanding events and professional sound reinforcement.
Ideal Match for FBT X-LITE and X-PRO
Designed as the perfect low-frequency extension for the FBT X-LITE and FBT X-PRO series, the X-SUB 115SA integrates neatly into FBT PA systems. Use it to support active tops, improve bass response and create a more complete full-range sound system.
DSP Processor with 4 Presets
The built-in DSP processor includes 4 presets, giving users control over low-frequency response and crossover behaviour. These presets provide 2 response options with 2 different cut-off frequencies, allowing the subwoofer to be adapted to different speaker combinations and sound requirements.
Professional Connectivity
The control panel provides two channels with stereo combo XLR / jack inputs and outputs, stereo XLR high-pass filter outputs, level control, preset switch, phase reversal switch and PRT / LMT LED indicators. This makes it easy to integrate into a professional PA system.
Rugged Birch Plywood Cabinet
The X-SUB 115SA is built from robust 15 mm birch plywood with a scratch-resistant black painted finish. The cabinet is designed to satisfy both portable and installation requirements, offering durability, a professional appearance and practical handling.
Practical Transport & Mounting
The subwoofer includes an M20 top-mounted stand adapter for mounting a satellite speaker above the sub, plus two FBT-designed aluminium handles for transport. Four optional 100 mm wheels can also be installed for easier movement between venues and events.
