FBT SUBLINE 118SA — 1×18″ Active Powered Install Subwoofer
SUBLINE 118SA Overview
The FBT SUBLINE 118SA is a professional active subwoofer built for installations and sound reinforcement applications where authoritative, precise low-frequency reproduction is essential. At its core is an 18″ high-excursion woofer with a 3″ voice coil, driven by a 1200W Class D amplifier for efficient, high-output bass performance. The integrated amplification eliminates the need for external processing, simplifying system design and reducing rack overhead. This subwoofer is well suited for system integrators, installed sound engineers, and venues requiring consistent, high-impact bass reinforcement.
The SUBLINE 118SA’s self-contained active design streamlines deployment in fixed installations, reducing cabling complexity while delivering the headroom required for demanding acoustic environments.
