PreSonus AIR18S Powered Subwoofer

Designed to complement any full-range PA loudspeaker and a perfect companion for the PreSonus® AIR10, AIR12, and AIR15, the PreSonus 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 for a more customized performance: Since each venue has unique acoustics and each application makes different demands on a sound system, PreSonus has equipped the 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.

Perfect for installs or mobile applications: Although it has a rugged, tour-grade birch enclosure, the PreSonus AIR15s 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 castor 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 AIR15s sports two combo XLR and 1/4” 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.
