FBT SUBLINE 112SA

SUBline: a "live" approach to bass by FBT

The FBT SUBline 112SA is designed as a powered subwoofer for live performance: a 12" format easy to integrate, a wooden enclosure for a cleaner response in real conditions, and headroom reserve to maintain dynamic range. It positions itself as a low-end reinforcement solution for mobile setups, while remaining robust enough for regular gigs.

Who is it for, and what for: sound reinforcement, DJs, bands, events

This subwoofer is particularly suitable if you want to add bass to an existing system: 10"/12" front speakers, small column speakers, versatile monitors used as front speakers, etc. Its specified frequency response (at -6 dB) from 42 Hz to 140 Hz makes it relevant for amplified music, vocals with accompaniment, electronic music at moderate volume, or event performances where you want to feel the low end without distorting the mix.

Thanks to its design and max level, the SUBline 112SA is suitable for both mobile DJs and bands, service providers, concert bars, and multipurpose venues that want more present bass while keeping size and weight manageable (23 kg ).

DSP, connectivity, and integration: an easy-to-tune subwoofer

DSP with presets: tailor the bass to your setup

The built-in DSP offers 8 programs to adapt the subwoofer's behavior according to usage (music type, level, pairing with main speakers). This is a real time saver during setup: instead of multiple external adjustments, you select a coherent preset to get tighter, deeper, or more "percussive" bass depending on the context.

DELAY function: coherence and clarity in the low end

The presence of a DELAY allows aligning the SUBline 112SA with your main speakers, improving the clarity of attacks (kick drum, bass) and avoiding the impression of "out-of-sync" bass. This is especially useful when the subwoofer is placed differently from the rest of the system (front of stage, under riser, offset to one side, etc.).

XLR connectivity and output with Hi/Link switch

The SUBline 112SA features XLR inputs and XLR outputs with a Hi/Link switch, convenient for cleanly chaining your signal and adapting routing according to your system. The goal: simple integration in stereo or mono without complicating things on stage or in the control room.

Stage design: wood, transport, and M20 socket

The wooden enclosure provides solid performance for live use. The carrying handles facilitate handling, and the M20 socket allows installing a pole to place a satellite speaker above the subwoofer, achieving more homogeneous coverage and a more compact floor setup.
