The QSC AD-S112-sw-BK AcousticDesign Series 12-Inch 300W Surface-Mount Subwoofer (Black) is a passive, 8-ohm subwoofer designed to deliver powerful low-frequency reinforcement for foreground and background music systems. Supplied with a yoke mounting system, it complements QSC AcousticDesign full-range loudspeakers in commercial audio installations.
Featuring a weather-treated 12-inch paper-cone woofer with a 2.5-inch voice coil, the AD-S112-sw-BK provides 300W RMS power handling, a frequency range of 30 Hz to 135 Hz (-10 dB), and a peak maximum SPL of 121 dB.
Its Turbulent Flow Reduction (TFR) port optimizes enclosure resonance and airflow to help achieve higher output levels before port turbulence becomes audible.
