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 make 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 ¬" 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.
Easily Create Subwoofer Arrays
The AIR18s subwoofer provides the tools you need to create both cardioid and endfire arrays with ease to keep excess energy off the stage and in the audience where it is needed.
Creating a cardioid subwoofer array forms a more direct radiation pattern and the AIR18s simplifies this with an onboard DSP preset: Just stack two AIR18s subwoofers, with the top subwoofer facing away from the audience and toward the stage, and then set the top subwoofer to use its Cardioid DSP preset. Your two AIR-series subwoofers will then radiate in a directional
cardioid pattern, allowing greater steering control over low-frequency energy.
Alternatively, you may prefer to create an end-fire array for even more off-axis rejection. Simply place two AIR18s subwoofers one in front of the other facing the direction to which you want to steer your sub energy and enable the Endfire preset on the rear AIR18s. Need to make a larger subwoofer array? AIR subwoofers are equipped with a variable delay and polarity invert so you can easily build more complex systems.
Now Hear This
With flexible connectivity; a rugged, tour-grade enclosure; and plenty of Class D power, the AIR18s delivers the versatility and punch needed for permanent installs. Yet it's relatively lightweight and portable, making it an excellent choice for mobile use. Although designed to complement AIR-series full-range loudspeakers, the AIR18s is also an excellent companion for third-party loudspeakers. Most important, it sounds great, delivering outstanding low-end clarity and natural music reproduction.
