PreSonus AIR15s 15-inch Active Subwoofer

Designed to complement any full-range PA loudspeaker and a perfect companion for the PreSonus® AIR series, the AIR15s active subwoofer delivers a powerful, clear, and accurate low-end punch. With its 15-inch low-frequency transducer, driven by 1,200 watts (peak) of Class D power, it provides ample detailed bass, all the way down to 35 Hz. Despite its power, the AIR15s is portable, compact, and lightweight, with a rugged, tour-grade birch enclosure. It’s easy to transport and well-suited for mobile applications, as well as for installation, with integrated provisions for the included caster kit, ground-stacking provisions, and ergonomic handles on both sides. AIR-series subwoofers are easy to set up—use controls and signal-processing presets. Set them for normal front-of-house usage or pump up the low end with the Mo' Bass preset. Invert the polarity, use the lowpass filter to dial in a crossover frequency, adjust the main output level of the power amplifier, even turn off the grille LED for installed applications, all with the touch of a button. A variable alignment delay properly aligns your three-way system. Most subwoofers are essentially omnidirectional, which can cause feedback on stage and make monitoring difficult. Creating a subwoofer array helps keep excess energy off the stage and audience. AIR-series subwoofers provide the tools you need to create these arrays with ease. Most important, the AIR15s sounds great, delivering outstanding bass clarity and natural musical reproduction. 15-inch low-frequency driver with 3-inch voice coil 1,200W (peak) Class D power amplifier Maximum SPL 126 dB peak with 35 Hz to 160 Hz frequency response 2 combo XLR and ¼-inch line inputs and two XLR direct outputs Easy-to-use DSP performance presets: Normal (typical FOH use) and Mo' Bass (extended low-end performance) Position adjustment presets: Normal (no array), Cardioid (ground-stacked cardioid array), and Endfire (endfire cardioid array) Fully variable lowpass filter (sets crossover point) with presets for AIR15, AIR12, and AIR10 Alignment delay (adds time delay relative to full-range speaker) and polarity switch (inverts summed input signal) 2 comfortable ergonomic side handles, ground-stacking provisions, provisions for casters (caster kit included), and defeatable front-panel LED Rugged, tour-grade birch enclosure with textured finish, 17-gauge steel grille
