For larger systems and high-demand applications, the PreSonus AIR XD Sub 18 delivers powerful, extended bass that you can feel. Its 18-inch woofer with a 3-inch voice coil, powered by 2000 watts of Class-D amplification, produces up to 130 dB of output with low-frequency extension down to 33 Hz.

Smart DSP and Seamless Integration

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.

Built for Touring and Installations

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.

Men's Turtleneck Sweater
Color: Black, Size: X-Large
I really like this turtleneck sweater! The material is soft, warm, and feels high-quality without being too heavy. It has just the right amount of stretch, so it fits comfortably without feeling tight around the neck or sleeves. I’ve worn it both casually with jeans and dressed up — it looks great either way. I order another one in a different color.
