Presonus AIR-XD-SUB-15 – AIR XD Sub 15 Active Extended Definition Subwoofer

Designed for both mobile setups and permanent installations, the PreSonus AIR XD Sub 15 active subwoofer delivers deep, accurate low-end performance that perfectly complements any full-range PA—especially the AIR XD-series. Its 15-inch low-frequency driver with a 3-inch voice coil is powered by a robust 2000W Class D amplifier, producing clean, powerful bass down to 32 Hz and output levels up to 128 dB.

Advanced onboard DSP makes system integration fast and easy. A variable lowpass filter (60 Hz–150 Hz) lets you fine-tune the crossover point for a seamless transition to your tops, while custom presets optimize performance with AIR XD full-range loudspeakers. An onboard alignment delay and array presets simplify the setup of ground-stacked and end-fire subwoofer arrays. A vibrant full-color display provides intuitive control and precise metering.

Connectivity is flexible, with two mic/line combo inputs and direct outputs to accommodate a wide range of signal paths. Integrated Bluetooth with TWS Bridge Mode allows you to pair with a second speaker for wireless stereo playback—ideal for mobile DJs, weddings, corporate events, and more.

Despite its high output, the AIR XD Sub 15 is compact, lightweight, and road-ready. Housed in a durable 15mm wood enclosure, it includes ergonomic side handles, ground-stacking features, and built-in hardware for the included caster kit—making it easy to transport and deploy in any environment.
