PreSonus AIR18s 18-Inch Powered Subwoofer

Designed to complement any full-range PA loudspeaker, the AIR18s subwoofer delivers a powerful, clear, and accurate low-end punch and is a perfect companion for the PreSonus® AIR10, AIR12, and AIR15 loudspeakers. With its 18-inch low-frequency transducer, driven by 1,200 watts (dynamic) of Class D power, it provides plenty of detailed bottom end—all the way down to 30 Hz. Yet it is portable and well-suited for mobile applications, as well as installed systems.

Since each venue has unique acoustics and each application makes different demands on a sound system, PreSonus has equipped AIR-series subwoofers with easy-to-use controls and signal-processing presets. Set your subs for normal front-of-house use or get an even bigger low-end with the Mo' Bass preset. Set them to perform in an array. Reverse polarity, use the lowpass filter to set a crossover frequency, 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.

About Powered Speakers at Sound Productions

Get all the features you need right out of the box with powered speakers from Sound Productions! All speakers need a sort of amplifier to function. Powered speakers (also known as active speakers or self-powered speakers) have built-in amplifiers, so they’re ready to connect to your audio source without any other required accessories—making them great for environments where space is limited.

Powered speakers are typically the go-to choice for portable use because they’re affordable, easy to set up, and simple to use as standalone sound systems. They’re great for achieving an immersive audio experience with the minimal amount of hassle—perfect for delivering a polished performance in smaller venues that may not have their own sound system installed. With fewer components to pack, they’re also a great choice for traveling events, such as mobile DJ performances or adding music to an outdoor event. Many models include other built-in features such as effects, compressors, and more to make one powered speaker virtually a standalone PA system!
