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 (dynamic) of Class D power, it provides plenty of detailed bottom end - all the way down to 35 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, 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.

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.

Whatever full-range speaker you choose, aligning the subwoofer to its full-range companion will yield tighter bass response.

Presonus 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.
