PreSonus AIR XD SUB-18 — 1500W 18" Powered Subwoofer

The PreSonus AIR XD SUB-18 is an 18-inch powered subwoofer designed for live sound, DJ, and event applications where serious low-end is needed without the cost or weight of touring-tier subs. Part of PreSonus's AIR XD series — the entry into pro-grade PA from a brand best known for recording interfaces and studio gear.

The 1500W Class-D amplifier drives an 18" woofer for deep, controlled bass extension. Onboard DSP includes preset voicings and crossover options to integrate with PreSonus tops or other full-range speakers. The integrated M20 pole socket on top accepts a satellite speaker for instant stereo or mono PA setups.

Ideal for: mobile DJs, small to medium-room live sound, churches, schools, restaurants and bars adding sub-bass to a PA system, and any installation where 18" sub performance is needed at a working-musician price.
