PreSonus AIR XD Sub 15 1 x 15-Inch Active Extended Definition Subwoofer

The PreSonus AIR XD Sub 15 is engineered to deliver brutally powerful, low-end definition for both mobile rigs and fixed installations. At its heart is a custom 15-inch low-frequency driver with a beefy 3-inch voice coil, offering tight, dynamic bass with minimal distortion, even when you push the limits. A robust 2,000-watt Class-D amplifier drives this system, delivering up to **128 dB SPL** for deep, room-filling low frequencies. Whether you're driving it flat-out for live shows or dialing it in for subtle reinforcement, the Sub 15 gives you serious output and headroom.

Flexibility is built in with DSP-based tuning features-variable low-pass filter, alignment delay, crossover controls, and specialized presets including “Mo’ Bass” mode and cardioid / end-fire array modes. A full-color LCD screen offers intuitive control over the tuning, ensuring you get tight, accurate bass tailored to the room, your main/full-range speakers, or your performance needs. Connectivity includes combo XLR/TRS line inputs, link outputs, and built-in Bluetooth with TWS Bridge Mode for wireless pairing with full-range AIR XD speakers.

Rugged, road-worthy build meets transport-friendly design. The cabinet is constructed of 15 mm plywood, with a steel grille (1.5 mm), dual side handles, and provisions for ground-stacking. Casters are included so you can roll it easily. The enclosure is designed for both durability and usability-built for heavy use, whether flown, ground-stacked, or rolled to gigs. Voltage handling is universal: 100-240 VAC, 50-60 Hz, with appropriate current draw in different mains environments.
