SUBline 218SA: the "double 18-inch" choice for FBT systems
The FBT SUBline 218SA fits into the "touring-ready" approach of the SUBline series: a powered subwoofer in wood, designed to effectively complement satellite speakers and build a coherent system for live performances. Its dual 18-inch (46 cm) architecture aims for a clear goal: to provide air volume, depth, and a comfortable level reserve, while remaining easy to integrate thanks to its XLR connectivity and DSP presets.
Intended uses and target profiles
This subwoofer is aimed at service providers, DJs, technicians, and bands looking for a sub capable of handling demanding programs: electronic music, hip-hop, pop, rock, or any context where the low end must remain present without collapsing at high volume. Its omnidirectional dispersion makes it a solid foundation for many setups (front of house, cluster, center fill), and the built-in DELAY facilitates time alignment with the tops according to distance and stage configuration.
