PreSonus® AIR18s Active Sound-Reinforcement Subwoofer, Black
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 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.

- Ground-stacked and end-fire presets to quickly create a cardioid subwoofer array
Creating Subwoofer Arrays
Two subwoofers in a traditional stereo configuration can cause a buildup of excess energy onstage. AIR subwoofers’ Cardioid DSP preset makes it easy to create a cardioid array with a more direct radiation pattern, keeping energy offstage and in the audience. Or create an end-fire array for even more off-axis rejection, using the Endfire preset.
AIR18s Inputs, Outputs and More
The AIR18s sports two combo XLR and ¼-inch TRS line-level inputs with level control, and throughputs are provided to connect full-range systems or multiple subwoofers in larger systems. You can even defeat the front power-indicator LED for low-visibility installs or set it to illuminate only when the protection limiter is engaged.
System Alignment and Crossover Settings
The AIR18s’ variable alignment delay properly aligns your three-way system, whether the full-range loudspeaker is placed atop the subwoofer, using the sub pole, or is placed a few feet away. A variable lowpass filter enables you to dial in the best crossover point. Optimized settings are provided for AIR-series full-range loudspeakers.
