PreSonus AIR18s Active Subwoofer

The PreSonus AIR18s is the larger of the AIR active subwoofers, with an 18-inch transducer driven by 1,200 watts peak of Class D power for deep, detailed low end down to 30 Hz. The rugged tour-grade birch enclosure stays manageable to transport despite its output.

Signal-processing presets cover normal front-of-house use or the low-boosting Mo' Bass mode, and controls for polarity, lowpass crossover, output level, and a defeatable grille LED make it easy to integrate. A variable alignment delay times it to the mains, and cardioid-array tools direct sub energy toward the audience. Ships with a caster kit and includes ground-stacking provisions and dual side handles.
