The AIR18S from PreSonus
is a versatile and customizable subwoofer featuring 1200W of power and
enhanced digital tuning functions, well suited for live bands, DJs,
clubs, event halls, bars, speaking engagements, and more. The subwoofer
is designed to work with 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 utilizes 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 137 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 customize the subwoofer for a number of applications including Mo'Bass, FOH, Cardioid, and Endfire presets. The cardioid and endfire 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.
