The PreSonus AIR18S Active Sound-Reinforcement Subwoofer is a versatile and customisable subwoofer featuring 1200W of power and enhanced digital tuning functions, well suited for live bands, DJs, clubs, event halls, bars, speaking engagements, and more. It's designed for the AIR10, AIR12, and AIR15 full range speakers, but is quite capable of adding low end to any sound system, regardless of manufacturer. The AIR18S utilises a single 600W (continuous) Class-D amplifier to power the 18" woofer for efficient and clean low end performance with a max SPL output of 129 dB SPL and frequency response of 35 Hz to 150 Hz (-3 dB).
The integrated and easy-to-use digital signal processor (DSP) allows you to customise the subwoofer for a number of applications including Mo'Bass, FOH, Cardioid, and End-fire presets. The cardioid and end-fire presets allow for off axis rejection and a uniform bass response throughout the room. Additionally, the variable low pass filter and variable alignment delay functions allow you properly dial in your subs with any available tops. The Air18S ships with a power cord and a caster kit.
