PreSonus AIR18s - 1200W 18-inch Powered Subwoofer with 3-inch Voice Coil and DSP in Black Finish

The PreSonus AIR18s powered subwoofer is engineered to deliver a deep, powerful low-end punch that complements any full-range PA loudspeaker, making it the ideal addition to the PreSonus AIR-series speakers. Its impressive 18-inch low-frequency driver, paired with a 3-inch voice coil and driven by 1,200W peak Class D power, produces crystal-clear, extended bass response down to an incredible 30 Hz, ensuring that every performance resonates with detailed low-end clarity.

Designed for both mobile and installed applications, the AIR18s boasts a rugged, tour-grade birch enclosure that not only provides durability but also facilitates portability. Despite its substantial output and robust performance, the subwoofer remains lightweight and compact, equipped with integrated provisions for a caster kit, ergonomic side handles, and ground-stacking capabilities. This versatility makes the AIR18s perfect for both live performances and permanent installations, ensuring exceptional sound quality wherever it's placed.

The AIR18s is equipped with advanced signal processing features that allow users to easily tailor the subwoofer's performance to their needs. The DSP includes two primary presets: Normal, for typical front-of-house use, and Mo' Bass, which provides extended low-end performance for those who need extra power in their bass frequencies. With a fully variable lowpass filter, users can set the crossover point precisely, and alignment delay and polarity switches further enhance system integration. The subwoofer also includes location-specific adjustment presets for Normal, Cardioid (for ground-stacked cardioid array configurations), and Endfire (for endfire cardioid array setups), allowing users to optimize output for a variety of configurations.

Offering seamless integration with full-range speakers, the AIR18s subwoofer is equipped with 2 combo XLR and 1/4-inch line inputs, as well as two XLR direct outputs, ensuring versatile connectivity with various audio sources. The built-in DSP provides an LCD screen for easy access to EQ and preset settings, allowing users to fine-tune their sound effortlessly. The AIR18s delivers maximum SPL of 129 dB peak, making it a powerful tool for high-output environments, while its frequency response of 30 Hz to 150 Hz ensures that low-end clarity is maintained even at extreme levels.

For added convenience, the AIR18s subwoofer comes with groundstack provisions, caster provisions (with the included caster kit), and a defeatable front-panel LED, making it easy to transport and set up in a variety of settings. Whether for high-energy performances or enhanced low-end reinforcement in an installed sound system, the AIR18s provides the performance and flexibility you need.
