PreSonus AIR18s

The active PreSonus AIR18s subwoofer is suitable for both mobile applications and permanent installations, delivering powerful, transparent, and precise deep bass reproduction down to 35 Hz with its 18" woofer and robust 1,200 W Class-D amplifier. With the DSP presets, you can configure the system for an extended bass range and set up groundstack or end-fire arrays. The variable alignment array ensures optimal time correction for your 3-way system. Use the low-pass filter to set a crossover frequency for a seamless transition between the subwoofer and full-range system, control the master output level for the amplifier, turn off the LED behind the grille for permanent installations if necessary, or configure it to light up only when the limiter protection circuit is active—all these functions are easily accessible at the push of a button. AIR18s subwoofers come with groundstack provisions and casters.
