Description
- 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.
Powerful, clear, accurate low-end performance.
Designed to complement any full-range PA loudspeaker and a perfect companion for the PreSonus® AIR-series full-range loudspeakers, the AIR18s subwoofer delivers a powerful, clear, and accurate low-end punch. With its 18-inch low-frequency transducer, driven by 1,200 watts (dynamic) of Class D power, it provides plenty of detailed bottom end— down to 30 Hz. And its compact form factor ake it equally well suited for mobile and installed applications.
Equally at home in mobile and installed systems.
Although it has a rugged, tour-grade birch enclosure, the PreSonus AIR18s is much more compact and lightweight than you’d expect from a subwoofer that can deliver this much power. With integrated provisions for the included castor kit, ground-stacking provisions, and ergonomic handles on both sides, it’s easy to transport for mobile applications, while offering the features and performance needed for demanding installs. The AIR18s sports two combo XLR and ¼” TRS line-level inputs with level control, and throughputs are provided to connect full-range systems or multiple subwoofers in larger systems. You can even defeat the front power-indicator LED for low-visibility installs.
The perfect companion.
AIR15s subwoofers can be used with virtually any full-range loudspeaker thanks to an onboard variable lowpass filter that allows you to dial in the best crossover point for your system. Optimized settings are provided for the AIR10, AIR12, and AIR15 full-range loudspeakers. Whichever full-range speaker you choose, aligning the subwoofer to its fullrange companion will yield tighter bass response. AIR18s subwoofers make it easy, with a variable alignment delay that properly aligns your three-way system, whether the full-range loudspeaker is placed atop the subwoofer, using the sub pole, or is placed a few feet away.
Application and Deployment
The AIR18s is equipped with a screw-lock pole cup to support a top-mounted full-range enclosure for ground-stacked applications. When with full-range AIR-series loudspeakers, PreSonus supports a maximum subpole height of 31 inches. Other configurations have not been tilt-tested for safety and should be managed with caution. Groundstack provisions allow additional stability for cardioid arrays and standard double stacking.
