Description
- Equally at home in mobile and installed systems, PreSonus AIR18s active subwoofers feature an 18-inch LF driver, driven by 1,200W of Class D power for a powerful, clear, and accurate low-end punch. A variable lowpass filter lets you dial in upper frequency limit for a smooth transition to your full-range system, and DSP presets let you accommodate different applications and quickly create ground-stacked or end-fire subwoofer arrays.

Powerful, Clear Low-end Performance
The PreSonus AIR18s is a compact 18″ subwoofer with 1200W Class D power, delivering deep, clear, and accurate low-end down to 30 Hz, making it a powerful and versatile solution for both mobile performances and installed sound systems.

Ideal for Mobile and Installed Use
The PreSonus AIR18s features a rugged birch enclosure in a compact, lightweight design with built-in handles, caster support, and stacking options for easy transport and mobile use, while offering flexible XLR/TRS inputs, throughputs, and installation-friendly controls for demanding sound systems.

The Perfect Companion
The PreSonus AIR18s features a variable lowpass filter with optimized presets for AIR speakers and an adjustable alignment delay, allowing precise crossover tuning with any full-range system for tighter, more accurate bass and improved overall performance.

Application and Deployment
The PreSonus AIR18s includes a screw-lock pole cup and ground-stacking support, allowing secure top-mounted setups with AIR-series speakers up to 31 inches, while enabling stable configurations like cardioid arrays and double stacking for flexible system setups.
