The MITUS 118FSA FSCA is an active, cardioid-arrayable subwoofer engineered for professional sound reinforcement in both touring and fixed installation environments. With its compact hybrid band-pass design, the MITUS 118FSA FSCA delivers the extended low-frequency response and precision required in high-output audio systems. It is purpose-built to complement the MITUS 206LA line array, offering scalable deployment options for ground-stacked or suspended configurations. The unique design allows the enclosure to be configured for either front-firing (FSA) or rear-firing (FSCA) use, supporting efficient cardioid setups with significant rear rejection. This makes it highly suitable for venues where controlled low-frequency dispersion is essential, such as theatres, houses of worship, concert halls, and outdoor stages. The MITUS 118FSA FSCA incorporates a high-excursion 18 inch B&C neodymium driver with a 3.5 inch voice coil, powered by a Class D amplifier delivering 1200 watts RMS. The system includes onboard DSP with eight presets, allowing for adaptable performance configurations including infra and cardioid modes. Housed in a durable 15 millimetre birch plywood enclosure finished with resistant black paint, the MITUS 118FSA FSCA ensures long-term reliability under demanding conditions. Designed to minimise power compression and turbulence through a large laminar-flow port, this subwoofer enables consistent output and efficient airflow, even at high volumes. As a low-frequency extension to the MITUS 206LA, the MITUS 118FSA FSCA is an essential component for audio professionals requiring precision, power, and control in demanding live and installed applications.
