PreSonus AIR XD Sub 18

The PreSonus AIR XD Sub 18 is a high-performance active subwoofer designed for professional use, delivering immense low-frequency extension and high sound pressure levels for large events and installations. Its custom-built 18-inch woofer with an enlarged voice coil provides efficient handling and deep, punchy bass with minimal distortion, while advanced tuning options—including variable low-pass filtering, alignment delay, and cardioid/end-fire array presets—ensure precise control of low-frequency performance in any environment. The AIR XD Sub 18 is powered by an efficient Class-D amplifier with 2,000 W, delivering clean, consistent performance with exceptional headroom for demanding live sound applications. A 2.6-inch LCD color display offers intuitive metering, system control, and quick access to DSP presets, EQ, and tuning modes. The integrated Bluetooth feature with TWS bridge mode allows for wireless stereo pairing with AIR XD full-range speakers, while flexible routing and direct outputs facilitate seamless integration into FOH or monitoring setups. Thanks to its sturdy wooden enclosure with ergonomic handles, the ability to stack on the floor, and built-in wheel mounts, the AIR XD Sub 18 is as portable as it is powerful, whether stacked, flown, or permanently installed.
