Q 118SA

The Q 118SA Processed Active Subwoofer delivers high-performance low-frequency reinforcement, making it suitable for a wide range of professional audio applications. Featuring an 18-inch woofer with a 4-inch voice coil, the Q 118SA is powered by a 1200W RMS Class D amplifier with a switch mode power supply for efficient energy use. Its onboard DSP offers six selectable presets including GENERAL, DEEP, PUNCH, and INFRA, each optimised for distinct frequency responses and dynamic needs. The DEEP and INFRA modes enhance low-frequency extension down to approximately 40Hz, while PUNCH concentrates output in the 60 to 95Hz range. Cardioid configuration presets support effective rear sound rejection in two or three-subwoofer setups. The subwoofer includes a digital six-step delay, stereo XLR inputs and links, phase and level controls, and a powerCON TRUE1 power system. Constructed from 18mm Baltic birch plywood with a durable coating, the Q 118SA also features M20 top mount sockets and four aluminium handles for ease of deployment.
