The FBT SUBline 115SA B-Stock is a compact, tour‑ready active subwoofer built to deliver tight, musical low end from a small footprint. Its Italian‑engineered Class‑D amplifier provides 700W RMS (1400W peak) to a high‑excursion 15-inch driver with a 3-inch voice coil, producing a confident 38–140 Hz frequency response and up to 135 dB SPL. A built‑in DSP streamlines setup with eight presets, selectable low‑pass points at 90 or 140 Hz, cardioid array presets, phase invert (0°/180°) and delay from 0.25 to 3.5 metres for precise alignment.
Connectivity is straightforward via stereo balanced XLR inputs and outputs, with level control and status LEDs for clear, quick operation. The rugged 15 mm birch plywood cabinet features internal bracing, an M20 pole mount and ergonomic aluminium handles, delivering durability at just 28 kg. Dimensions are 500 x 517 x 570 mm.
This B-Stock unit has been inspected and tested, is fully functional, and may show minor cosmetic signs of use. Ideal for pairing with compact active tops, it suits live sound, AV rental, events and installed audio where powerful, controlled bass is required.
