The PreSonus AIR XD Sub 18 active extended definition subwoofer pushes out serious low-end for mobile DJs, event techs, or permanent installs. This 18" powered sub uses a 3" voice coil and a 2000W Class-D amp to reach up to 130 dB output and a deep 33 Hz low frequency. The onboard DSP and full-color display make setup fast, offering alignment delay and array presets for ground-stacked or end-fire configurations.

Ergonomic handles and ground-stacking options simplify moving and setting up this subwoofer in busy event spaces or tour rigs.

Advanced DSP Streamlines Setup and Tuning

Digital signal processing in this subwoofer shapes the output for each space. The variable lowpass filter (60–150 Hz) helps blend bass with main speakers, preventing muddy transitions. Presets for AIR XD tops and array configurations speed up installation, making it easy to set cardioid or end-fire stacks. Fast tuning gets you focused bass in tough rooms, letting you control the sound stage for live or installed systems.

Wireless Streaming and Stereo Pairing Enhance Flexibility

Built-in Bluetooth with TWS Bridge Mode supports wireless audio streaming from your phone or tablet. Stereo pairing lets you link a second sub for left-right sound, useful for mobile events or corporate setups. You can run clean, reliable audio without messy cables, keeping your rig simple and organized when every second counts.

Intuitive Controls and Connections Simplify Workflow

Two XLR/1/4" combo inputs and direct outputs handle multiple sources, from mixers to instruments. The full-color screen gives clear metering and fast access to DSP settings, including alignment delay and polarity invert. Ground-stacking and array presets let you adjust for different venues without manual calculations. These features keep your system running smoothly and cut down on setup time in busy environments.
