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.

- 1,200W Active PA Subwoofer with 18" LF Driver
- Onboard mixer with 2 XLR/TRS combo inputs and stereo 1/8" input
- Variable lowpass filter dials in your upper-frequency limit from sub-bass to full-range
- Convenient DSP presets enable extended low end for ground-stacked or endfire subwoofer arrays
