Product details
Description
The black AcousticDesign Series QSC AD-S112sw is a 12" surface-mount 8-ohm subwoofer supplied with a yoke mounting system, making it suitable for low-frequency reinforcement in a variety of foreground and background music applications, a well-matched companion for QSC's AcousticDesign full-range loudspeakers.
Outfitted with a 12" weather-treated woofer on a 2.5" voice coil, the AD-S112sw direct-radiating subwoofer offers 300W RMS power handling, a frequency range of 30 to 135 Hz (-10 dB), and a peak maximum SPL of 121 dB. Its TFR (Turbulent Flow Reduction) port optimizes resonance tuning and yields higher output SPLs before turbulence.
The AD-S112sw utilizes a 4-pole Euroblock connector under a sealed input cover for easy wiring and protection from moisture. Featuring a rugged ABS enclosure and a powder coated aluminum grille, the AD-S112sw boasts dust and splash resistance beyond IP54 ratings for worry-free operation indoors or outside.
