Description
The CDL Sub18 is an 18-inch active subwoofer engineered to deliver tight, coherent low-frequency reinforcement for live sound and installed systems. It combines a high-excursion 18-inch driver and an integrated Class D amplifier to provide punchy, accurate sub-bass. The cabinet design and onboard processing focus on musical impact and system integration.
The subwoofer features an 18-inch LF transducer with a 4-inch voice coil and 7 mm of driver travel before over-excursion, enabling higher excursion without distortion. An integrated 2,000 watt peak (1000 watt RMS) Class D amplifier supplies the headroom required for clean transient response. A unique ported enclosure with four triangular corner ports improves efficiency while minimizing port noise and phase anomalies.
Performance metrics include a maximum SPL of 135 dB peak and a stated response of 36 Hz to 144 Hz, making the CDL Sub18 suitable for reinforcing modern music and speech content. The onboard menu provides presets, variable low-pass filtering and polarity invert to tailor the sub’s performance to your mains. The amplifier and electronics are designed for low noise and reliable dynamic range.
Connectivity options include balanced XLR input and balanced XLR direct output for chaining or integration with processors. A menu-driven low-pass control adjusts the transition point to full-range loudspeakers and output power preset selection adapts the output to different system requirements. Locking powerCON AC in and out connectors support reliable mains distribution in touring and fixed installations.
The CDL Sub18 adapts to ground-stacked and flown applications via an integrated M20 threaded pole mount for stacking up to two CDL-series loudspeakers and integrated M10 fly points for suspension. Two side handles and a rugged 15 mm eucalyptus plywood enclosure with Chemline Polyurea finish and a tour-grade steel grille simplify transport and installation. The enclosure shape and port placement are optimized to reduce baffle reflections and improve phase coherence with tops.
PreSonus backs the CDL-series with a six-year limited warranty, reflecting confidence in build quality and component selection. The subwoofer’s convection cooling and robust hardware provide reliable operation in both mobile and installed environments. Overall, the CDL Sub18 balances compact footprint, controlled low-end output and integration features to deliver professional sub-bass in a variety of AV applications.
