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 end-fire subwoofer arrays. A variable alignment delay properly aligns your three-way system. Use the low pass 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.



With flexible connectivity; a rugged, tour-grade enclosure; and plenty of Class D power, the AIR18s delivers the versatility and punch needed for permanent installs. Yet it’s relatively lightweight and portable, making it an excellent choice for mobile use. Although designed to complement AIR-series full-range loudspeakers, the AIR18s is also an excellent companion for third-party loudspeakers. Most important, it sounds great, delivering outstanding low-end clarity and natural music reproduction.
