The Presonus AIR18s is an 18" powered subwoofer that delivers a powerful, clear, accurate low end via way of the 1200w Class D power section. The AIR18s will complement any full-range PA loudspeaker and is a perfect companion for the PreSonus AIR10, AIR12, and AIR15 speakers.
Presonus have equipped the AIR18s with easy to use controls and signal processing presets allowing it to be used for each application. 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.
Thanks to its compact lightweight design, the AIR18s can not only be used for installed systems but also for mobile applications. It comes with a caster kit, ground-stacking provisions and ergonomic handles on both sides for easy handling and transportation.
When it comes to connectivity, the AIR18s features 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.
Although recommended for use with the AIR full-range speakers, the AIR18s will happily function with any loudspeaker. It features 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. In addition, an adjustable lowpass filter allows you to dial the best crossover point.
With flexible connectivity; a rugged, tour-grade enclosure; and plenty of Class D power, the AIR15s delivers the versatility and punch needed for permanent installs. Yet it’s relatively lightweight and portable, making it an excellent choice for mobile use too.
