Presonus AIR18S

18in 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 delivers a powerful, clear, and accurate low-end punch. With its 18-inch low-frequency transducer, driven by 1,200 watts of Class D power, it provides plenty of detailed bottom end—all the way down to 35 Hz. Yet it is portable and well suited for mobile applications, as well as installed systems.
