PreSonus CDL SUB18  (PreSonus CDL-SUB-18)

Active Line Array Subwoofer

PreSonus CDL Sub18 is an active line array subwoofer designed for articulated, high-output bass reinforcement in live sound and permanent installation environments. Built for use in clubs, theaters, houses of worship, event production, and touring systems, it delivers deep low-end impact, controlled performance, and flexible deployment whether used on the ground or as part of a flown array.

PreSonus CDL Sub18 Competitive Differences

• Combines an 18-inch custom woofer with 2000W peak Class-D amplification for powerful sub-bass output in demanding live sound applications
• Supports both ground-stacked and flown configurations with onboard DSP controls, M20 pole mounting, and M10 fly points for flexible system design

PreSonus CDL Sub18 Description

The PreSonus CDL Sub18 is built to provide strong, controlled low-frequency reinforcement for professional sound systems that need serious output and deployment flexibility. Its custom 18-inch woofer features a 4-inch voice coil and 7 mm of excursion, helping it reproduce sub-bass content with the kind of authority needed for live music, spoken word reinforcement, and high-energy playback applications. Whether used in portable production systems or fixed installations, it is designed to deliver bass that fills the room with clarity and impact.

Powered by a Class-D amplifier rated at 500W RMS, 1000W program, and 2000W peak, the CDL Sub18 is made to handle demanding performance environments while keeping weight and efficiency manageable. The bass-reflex enclosure helps extend low-frequency performance, and the 42 Hz to 150 Hz response range supports tight integration with compatible full-range loudspeakers. Onboard DSP functions including a variable low-pass filter, output power preset selection, and polarity invert make it easier to tailor the system for different room layouts and array configurations.

For system design flexibility, the PreSonus CDL Sub18 can be deployed as a ground-stacked subwoofer or integrated into a flown rig. Up to two subwoofers can be flown with five CDL12 full-range tops, making it a strong choice for scalable line-array and point-source systems. An M20 threaded pole socket allows convenient mounting of compatible CDL loudspeakers above the sub, while M10 mounting points support suspended installation in more permanent or advanced production setups.

Built for the realities of live sound, the enclosure combines a rugged cabinet with a tour-grade 1.2 mm steel grille, integrated side handles, and practical rear-panel connectivity. Balanced XLR input and output, powerCON input and output, and front-panel status indicators for signal, level, limiting, and clipping make the CDL Sub18 easy to integrate and monitor on the job. This is a solid low-frequency solution for production companies, venues, and installers needing scalable PreSonus CDL system performance.
