PreSonus AIR XD Sub 18 Active Extended Definition Subwoofer

Designed for both mobile and installed systems, the PreSonus AIR XD Sub 18 delivers up to 130 dB of powerful, accurate low-end with an 18-inch driver, 2000W Class D amp, variable lowpass filter, and DSP presets for seamless integration and advanced array configurations.

Equally suited for mobile systems and fixed installations, the PreSonus AIR XD Sub 18 active subwoofer delivers powerful, accurate low-end performance and integrates seamlessly with any full-range PA—especially the AIR XD-series. Its 18-inch woofer with a 3-inch voice coil is powered by 2000W of Class D amplification, providing deep, punchy bass down to 33 Hz and output levels up to 130 dB.

Advanced onboard DSP makes setup and tuning fast and easy. A variable lowpass filter (60–150 Hz) lets you fine-tune crossover points for smooth transitions to your mains. Presets for AIR XD full-range loudspeakers ensure plug-and-play integration, while onboard alignment delay and array presets allow quick configuration of ground-stacked or end-fire subwoofer arrays. A full-color display offers intuitive navigation, precise metering, and easy control of all settings.

The AIR XD Sub 18 includes two XLR/¼" combo inputs with direct outputs for flexible signal routing. Built-in Bluetooth with TWS Bridge Mode enables reliable wireless audio streaming and stereo pairing with a second speaker—ideal for mobile events, parties, and corporate setups.

Despite its size and output, the AIR XD Sub 18 is compact, portable, and rugged. Its 15mm tour-grade wood enclosure includes ergonomic side handles, integrated caster mounts, and ground-stacking provisions—making it easy to transport and deploy for both touring and installed sound environments.
