The MITUS 212FSA is a professional-grade processed active subwoofer engineered for high-output low-frequency reinforcement in flown or ground-stacked configurations. Developed to integrate seamlessly with the MITUS 206LA line array, the MITUS 212FSA features a compact vented band-pass design that ensures efficient bass response within a focused frequency range. Equipped with two 320 mm B&C neodymium magnet subwoofers and 75 mm voice coils, it delivers consistent low-frequency performance across a response range of 45 Hz to 120 Hz. The system is powered by a 1200-watt RMS Class D amplifier, paired with a switch mode power supply and onboard DSP for reliable operation under demanding conditions. The DSP includes eight preset configurations, including cardioid and infra modes, allowing for system flexibility across various live sound, touring, and fixed installation applications. Control and signal options include XLR input and link, volume, delay, phase adjustment, and a ground-lift function for noise management. Housed in a durable 15 mm birch plywood enclosure finished with black scratch-resistant paint, the MITUS 212FSA also features an M20 top mount socket, enabling pole-mounted configurations when required. Its robust design and acoustic performance make the MITUS 212FSA a valuable low-frequency extension solution for professional audio deployments requiring compact format and flyable compatibility.
