Presonus AIR-XD-SUB-18 – AIR XD Sub 18 Active Extended Definition Subwoofer

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.
