FBT Audio SUBline 115SA 15-Inch Active Powered Subwoofer
The FBT SUBline 115SA is a compact yet powerful 15-inch active subwoofer designed for DJs, live sound, venues, bands, clubs, hire companies and mobile PA systems. With a 700W RMS Class D amplifier, high-output 15-inch woofer, onboard DSP and up to 135dB peak SPL, it delivers deep, punchy low-end performance in a portable Italian-made cabinet.
Loaded with a 15-inch high-excursion woofer and 3-inch voice coil, the SUBline 115SA provides impressive low-frequency output from a compact cabinet. Its built-in amplifier means no external power amp is required, making it ideal for fast setup PA systems, DJ rigs and portable event sound.
Whether you are upgrading a DJ PA system, adding low-end support to a live sound setup or building a compact venue sound system, the FBT SUBline 115SA 700W RMS active subwoofer is a reliable, powerful and great-sounding choice.
Powerful 15-Inch Bass Performance
The SUBline 115SA is built around a 15-inch high-excursion woofer with a 3-inch voice coil, giving it the punch and depth needed for DJ sets, dance music, live bands and venue sound systems. It adds serious low-end weight while remaining compact enough for regular mobile use.
700W RMS Class D Amplification
The built-in 700W RMS Class D amplifier provides strong, reliable output without the need for an external amplifier. This makes the SUBline 115SA easy to integrate into mobile PA systems, active speaker setups and compact event sound rigs.
Built-In DSP Control
The onboard digital signal processor gives users flexible control over the subwoofer’s performance. With 8 presets, EQ options, low-pass crossover settings, delay adjustment and phase reverse, the SUBline 115SA can be tailored to work with active PA tops, compact line array systems or full-range loudspeakers.
Stereo XLR Connectivity
The SUBline 115SA includes stereo XLR inputs and outputs, making it easy to connect from a mixer or controller and route signal through to active tops. This makes it suitable for stereo PA systems, DJ rigs, band setups and professional event sound.
Compact and Portable Design
Despite its powerful bass performance, the SUBline 115SA remains portable at around 28kg. This makes it a strong choice for mobile DJs, hire companies and venues that need serious bass without moving a huge cabinet.
Italian-Made Birch Plywood Cabinet
The enclosure is made from Baltic birch plywood and manufactured in Italy, giving it the strength and durability required for regular professional use. The cabinet is designed for mobile sound, venues, hire stock and professional PA applications.
