PreSonus Air-XD-Sub-18 1 x 18" Active Extended Definition Subwoofer SKU# 2779100110

The PreSonus Air XD Sub 18 is a high-performance active subwoofer designed for professional use, delivering massive low-end extension and high SPL for large-scale events and installations. Its custom 18-inch low-frequency driver with enlarged voice coil provides efficient power handling and deep, punchy bass with minimal distortion, while advanced tuning options—including variable lowpass filtering, alignment delay, and cardioid/end-fire array presets—ensure precise control of low-frequency performance in any environment.

Powered by 2,000W of efficient Class D amplification, the Air XD Sub 18 delivers clean, consistent output with exceptional headroom for demanding live sound applications. A full-color 2.6” LCD provides intuitive metering, system control, and fast access to DSP presets, EQ, and tuning modes.

Built-in Bluetooth with TWS Bridge Mode enables wireless stereo pairing with Air XD full-range speakers, while flexible routing and direct outputs allow seamless integration into FOH or monitoring setups. Rugged wood enclosures with ergonomic handles, ground-stacking provisions, and built-in caster mounting make the Air XD Sub 18 as portable as it is powerful, whether stacked, flown, or installed permanently.

A full-color display provides clear navigation of system tuning, metering, and setup tools. Advanced onboard DSP includes a variable low-pass filter (60 to 150 Hz) for seamless crossover to tops, along with alignment delay and custom presets for AIR XD loudspeakers. Specialized array modes make it simple to configure ground-stacked or end-fire cardioid arrays for controlled low-end coverage.

Despite its size and output, the AIR XD Sub 18 is designed for portability. Its rugged 15mm wood cabinet features ergonomic handles, integrated caster provisions, and stacking hardware for easy transport and secure deployment. Built-in Bluetooth with TWS Bridge Mode enables wireless stereo playback, making it equally suitable for mobile DJs, touring acts, and professional venues.
