PreSonus - AIR18s (Active Sound-Reinforcement Subwoofer)
Designed to complement any full-range PA loudspeaker, and a perfect companion for the PreSonus AIR-series, the AIR18s active subwoofer delivers a powerful, clear and accurate low-end punch. With its 18-inch low-frequency transducer, driven by 1,200 watts (peak) of Class D power, it provides plenty of detailed bottom end, all the way down to 30 Hz.
Despite its power, the AIR18s is portable, compact and lightweight, with a rugged, tour-grade birch enclosure. It's easy to transport and suitable for mobile applications, as well as installs, with integrated provisions for the included caster kit, ground-stacking provisions and ergonomic handles on both sides.
AIR-series subwoofers feature easy-to-use controls and signal-processing presets. Set them for normal front-of-house use or boost the low-end with the Mo' Bass preset. Reverse polarity, use the lowpass filter to set a crossover frequency, adjust the power amp's master output level, even turn the grille LED off for installs - all at the touch of a button. A variable alignment delay properly aligns your three-way system.
Most subwoofers are essentially omnidirectional, which can cause feedback onstage and make monitoring difficult. Creating a subwoofer array helps keep excess energy off of the stage and in the audience. AIR-series subwoofers provide the tools you need to create these arrays with ease.
Most important, the AIR18s sounds great, delivering outstanding low-end clarity and natural music reproduction.
