The PreSonus Air18S active PA subwoofer exhibits a powerful, clear, and accurate low-end punch that belies its compact, lightweight form factor. An 18" woofer is powered by 1,200 watts delivered by a super-efficient Class D amplifier. A variable lowpass filter dials in the upper frequency limit from sub-bass to full-range, while DSP presets enable extended low-end performance, so creating ground-stacked or endfire subwoofer arrays is child's play. Great for both mobile use and permanent installations, the PreSonus Air18S active PA subwoofer is the perfect complement to the full-range Air10, Air12, or Air18 PA system.

Manufacture Description

AIR18s: Powerful, clear, accurate low end.

Designed to complement any full-range PA loudspeaker and a perfect companion for the PreSonus® AIR10, AIR12, and AIR15, the AIR18s subwoofer delivers a powerful, clear, and accurate low-end punch. With its 18-inch low-frequency transducer, driven by 1,200 watts of Class D power, it provides plenty of detailed bottom end—all the way down to 30 Hz. Yet it is portable and well suited for mobile applications, as well as installed systems.







Extensive controls enable customized performance.

Since each venue has unique acoustics and each application makes different demands on a sound system, we’ve equipped AIR-series subwoofers with easy-to-use controls and signal-processing presets. Set your subwoofers for normal front-of-house use or get an even bigger low-end with the Mo’ Bass preset. Set them to perform in an array. Reverse polarity, use the lowpass filter to set a crossover frequency, 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.





Equally at home in mobile and installed systems.

Although it has a rugged, tour-grade birch enclosure, the PreSonus AIR18s is much more compact and lightweight than you’d expect from a subwoofer that can deliver this much power. With integrated provisions for the included caster kit, ground-stacking provisions, and ergonomic handles on both sides, it’s easy to transport for mobile applications, while offering the features and performance needed for demanding installs. The AIR18s sports two combo XLR and ¼” 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.



Plays well with others.

Although we recommend AIR-series full-range loudspeakers, AIR18s subwoofers can be used with virtually any full-range loudspeaker. Whatever full-range speaker you choose, aligning the subwoofer to its full-range companion will yield tighter bass response. AIR18s subwoofers make it easy, with a variable alignment delay that 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. AIR-series subwoofers also are equipped with a variable lowpass filter that allows you to dial in the best crossover point for your system. Optimized settings are provided for the AIR10, AIR12, and AIR15 full-range loudspeakers.






Easily create subwoofer arrays.

Most subwoofers are essentially omnidirectional, radiating sound around the entire cabinet, which can cause feedback onstage and make monitoring more difficult. Creating a subwoofer array helps keep excess energy off of the stage and in the audience where it is needed. AIR-series subwoofers provide the tools you need to create these arrays with ease.




Hearing is believing.

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. Hear AIR-series loudspeakers for yourself at your favorite PreSonus dealer.
