FBT SUBLine 218SA - 2400W 2 x 18-inch Powered Bass Reflex Subwoofer with 3-inch Voice Coil in Black Finish

The FBT SUBLine 218SA is a high-performance powered bass reflex subwoofer designed to deliver powerful low-frequency extension and is an ideal complement for the FBT MUSE 210LA line array system or for ground stack applications. Built to meet the rigorous demands of professional audio environments, the SUBLine 218SA features two 18-inch custom-made woofers designed by B&C, each with a 3-inch voice coil, capable of producing exceptional bass response down to 30Hz. With a robust 1200W RMS Class D amplifier, the subwoofer can handle extreme levels, delivering a peak SPL of 140dB for immersive, thundering low-end sound.

The subwoofer is constructed with 0.70-inch Baltic birch plywood, providing both durability and a lightweight design, while the scratch-resistant black paint finish ensures it remains looking pristine despite heavy use in demanding environments. The FBT SUBLine 218SA is equipped with a DSP that offers six different presets, including cardioid and infra configurations, allowing for flexible sound optimization based on the venue and performance needs. The intuitive control panel features stereo XLR input and output connectors, volume control, preset selection, delay adjustment, and phase control (0° to 180°), with three status LED indicators for monitoring the system's status.

With two M20 top-mounted stand adapters, the FBT SUBLine 218SA can be easily paired with speaker stands for vertical placement, or stacked in a ground configuration, depending on the setup. The four aluminum handles provide easy transport, making it suitable for mobile applications, and the subwoofer's excellent SPL capabilities make it an ideal solution for live sound reinforcement, concert events, and installations where high-output bass is required. Manufactured entirely in Italy, the SUBLine 218SA combines advanced engineering, rugged construction, and outstanding performance to meet the highest standards in professional audio.
