FBT SUBline 112SA Active Subwoofer
The FBT SUBline 112SA is a compact yet powerful 12-inch active powered subwoofer designed for DJs, live sound, venues, mobile PA systems, bands, performers and fixed installations that need strong low-end performance from a small, easy-to-transport cabinet.
Weighing just 23kg, the SUBline 112SA delivers impressive punch and high SPL from a compact Italian-made birch plywood enclosure. Its 700W RMS Class D amplifier, 12-inch high-excursion woofer and 3-inch voice coil provide deep, controlled bass with a frequency range of 40Hz - 140Hz and maximum SPL of 130 / 133dB continuous / peak.
The SUBline 112SA has been redesigned with a bass-reflex configuration to extend low-frequency response across a wide range of FBT speaker systems. With onboard DSP, stereo XLR inputs and outputs, crossover options, delay control and phase reverse, it is easy to integrate into professional PA systems, mobile DJ rigs and compact event sound setups.
Compact 12-Inch Bass Performance
The SUBline 112SA uses a 320mm / 12-inch high-excursion woofer with a 75mm / 3-inch voice coil, delivering punchy low-frequency output from a cabinet that remains compact and highly portable. It is ideal for users who need professional bass without carrying a large subwoofer.
700W RMS Class D Amplification
The built-in amplifier is engineered and manufactured by FBT, providing 700W RMS and 1400W peak power. The Class D design keeps the subwoofer efficient, powerful and practical for regular professional use.
Built-In DSP with 8 Presets
The onboard digital signal processor includes 8 presets, allowing the SUBline 112SA to be matched to different FBT speaker systems and applications. The DSP includes EQ options, 90Hz or 140Hz low-pass crossover settings, cardioid configuration support, delay adjustment and phase reversal.
Stereo XLR Connectivity and 2.1 System Use
With stereo XLR inputs and outputs, the SUBline 112SA offers excellent input flexibility. It can be used as part of a standard PA setup or as a compact 2.1 system, allowing one subwoofer to feed left and right speakers in stereo for smaller gigs, ceremonies, bars, mobile DJ setups and event systems.
Delay, Phase and System Alignment
The control panel includes volume, EQ presets, an 8-step delay from 0.25m to 3.5m, a 0° / 180° phase reversal switch and 3 status LED indicators. These controls help with system alignment, room setup and integration with different top speakers.
Birch Plywood Cabinet Made in Italy
The SUBline 112SA is built from 15mm birch plywood with internal bracing and a scratch-resistant finish. The cabinet is made in Italy and designed for both portability and durability, making it suitable for mobile DJs, hire companies, venues and professional PA users.
Neutrik powerCON TRUE1 Connection
The Neutrik TRUE1 power connection provides a solid locking power connection and removes the need for a traditional power switch. This helps make setup secure, tidy and professional.
Practical Transport and Mounting
Two ergonomic aluminium FBT handles make the SUBline 112SA easy to carry, while the M20 top-mounted speaker stand socket allows compatible satellite speakers or poles to be mounted above the subwoofer.
