Presonus - AIR18s

18" 1200W Active Subwoofer

 

Designed to complement any full-range PA loudspeaker and a perfect companion for the PreSonus AIR10, AIR12, and AIR15, the AIR18s subwoofer is driven by 1,200W of Class D power, providing detailed, clear, accurate sub-lows all the way down to 35 Hz.

 

Equally at home in mobile and installed systems, PreSonus AIR18s active subwoofers feature an 18-inch LF driver, driven by 1,200W of Class D power for a powerful, clear, and accurate low-end punch. A variable lowpass filter lets you dial in upper frequency limit for a smooth transition to your full-range system, and DSP presets let you accommodate different applications and quickly create ground-stacked or end-fire subwoofer arrays. 

 

Equally at home in mobile and installed systems, PreSonus AIR18s active subwoofers feature a 18-inch LF driver, driven by 1,200W of Class D power for a powerful, clear, and accurate low-end punch down to 35 Hz. DSP presets enable extended low-end performance and let you create ground-stacked or end-fire subwoofer arrays. A variable alignment delay properly aligns your three-way system. Use the lowpass filter to set a crossover frequency for a smooth transition from sub-bass to full-range, adjust the master output level of the power amplifier, even turn the grille LED off for install applications or set it to illuminate only when the protection limiter is engaged—all at the touch of a button. AIR18s subwoofers also include integrated ground-stacking provisions and a castor kit.
