The FBT SUBline 115SA B-Stock is a compact, tour‑ready active 15-inch subwoofer designed to add authoritative low-end to modern PA systems. Built around an Italian‑engineered Class‑D amplifier delivering 700W RMS (1400W peak), it pairs a high‑excursion 15-inch driver with a 3-inch voice coil to produce a powerful 38–140 Hz response and up to 135 dB SPL. A built‑in DSP offers eight presets, low‑pass options at 90/140 Hz, cardioid array presets, phase invert (0°/180°) and delay settings from 0.25 m to 3.5 m, ensuring fast setup and precise system integration.
Connectivity and control are straightforward via stereo balanced XLR inputs/outputs, level control and clear status LEDs. The robust 15 mm birch plywood cabinet with internal bracing, M20 pole mount and ergonomic aluminium handles keeps weight to just 28 kg while remaining highly durable. Dimensions are 500 x 517 x 570 mm.
This B-Stock unit has been inspected and tested, is in full working order, and may show minor cosmetic signs of use. Ideal for reinforcing compact active tops such as FBT VENTIS 110A/112A, it’s a versatile choice for live sound, AV rental, events and installed audio looking for tight, musical bass.
