Designed to complement any full-range PA loudspeaker, the AIR18s subwoofer delivers a powerful, clear, and accurate low-end punch and is a perfect companion for the PreSonus® AIR10, AIR12, and AIR15 loudspeakers. With its 18-inch low-frequency transducer, driven by 1,200 watts (dynamic) 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.

Since each venue has unique acoustics and each application makes different demands on a sound system, PreSonus has equipped AIR-series subwoofers with easy-to-use controls and signal-processing presets. Set your subs 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.
