PreSonus AIR18s Powered PA Subwoofer
AIR18s
1 x 18” Active Subwoofer
Equally at home in mobile and installed systems, PreSonus AIR18s active subwoofers feature a 18-inch LF driver, driven by 1,200W of Class D power for a powerful, clear, and accurate low-end punch down to 35 Hz. DSP presets enable extended low-end performance and let you create ground-stacked or endfire subwoofer arrays. A variable alignment delay properly aligns your three-way system. Use the lowpass filter to set a crossover frequency for a smooth transition from sub-bass to full-range, adjust the master output level of the power amplifier, even turn the grille LED off for install applications or set it to illuminate only when the protection limiter is engaged—all at the touch of a button. AIR18s subwoofers also include integrated ground-stacking provisions and a castor kit.
