AIR15s Active Sound-Reinforcement Subwoofer

The PreSonus AIR15s active sound-reinforcement subwoofer is designed to complement full-range PA loudspeakers and pairs especially well with the PreSonus AIR series. Its 15-inch low-frequency transducer is powered by 1,200 watts peak of Class D amplification, delivering clear, accurate low-end punch with extension down to 35 Hz. The result is detailed bass response that supports music reproduction with clarity and natural balance. Despite its output, the AIR15s is built for portability and practical deployment. The compact, lightweight format is housed in a rugged tour-grade birch enclosure, with ergonomic side handles for transport. It is suited to both mobile applications and permanent installs, with integrated provisions for the included caster kit and ground-stacking. Operation is straightforward thanks to easy-to-use controls and onboard signal-processing presets. Users can select normal front-of-house operation or engage the Mo' Bass preset for enhanced low-end impact. Additional controls include reverse polarity, adjustable lowpass filter crossover, master output level, grille LED defeat for installs, and variable alignment delay for properly aligning a three-way system. AIR-series subwoofers also provide tools to help create subwoofer arrays, helping keep excess low-frequency energy off the stage and focused toward the audience.
