Presonus CDL-SUB18

The PreSonus CDL Sub18 is a powerful, Dante-enabled active subwoofer designed to deliver deep, controlled low-end performance for both mobile and installed sound systems. Equipped with a high-efficiency 18-inch driver and a massive 2,000W Class D amplifier, this subwoofer produces up to 135 dB of peak SPL, ensuring bass that you can both hear and feel. Its innovative ported enclosure design and robust build make it the ideal low-frequency foundation for CDL-series loudspeakers like the CDL12P and CDL10P.

Built for versatility, the CDL Sub18 features a rugged 15mm eucalyptus plywood enclosure with a Chemline Polyurea coating and integrated M10 fly points for suspended configurations. An M20 threaded pole mount supports ground-stacked setups with one or two CDL loudspeakers on top, while dual CDL Sub18s can be stacked for even more low-end power. Onboard DSP controls allow for easy configuration, including a variable low-pass filter, power output presets, and polarity inversion to fine-tune your system for any acoustic environment.

With XLR input and direct out connections, as well as locking powerCON in/out, the CDL Sub18 is built for seamless integration into professional audio rigs. Whether you're outfitting a permanent venue or hitting the road, it offers tight, articulate bass and system flexibility that make it a go-to choice for sound professionals.
