Bring thunderous, articulate low end to your sound system with the PreSonus CDL18s Active Subwoofer. Engineered to pair seamlessly with the CDL12 Constant Directivity Loudspeakers, the CDL18s delivers the chest-pounding bass and precision control you need for concerts, installations, houses of worship, and touring rigs. Powered by 2,000 watts of Class D amplification, its custom 18-inch low-frequency transducer produces explosive SPLs with impressive clarity, while a unique quad triangular port design reduces turbulence and baffle reflections for a tight, punchy response all the way down to the lowest frequencies. What sets the CDL18s apart is its advanced DSP speaker management and Dante-enabled connectivity. Integrated presets make setup simple, while Worx Control software unlocks powerful tools such as 8-band EQ, polarity invert, compression, limiting, and up to 800ms of delay, giving you full control over your system from your Mac or PC. With Dante networking, you’ll enjoy near-zero latency, seamless synchronization, and compatibility with a wide range of professional audio gear — all over a single Ethernet cable. Designed for versatility, the CDL18s offers a full range of deployment options, including pole-mounted configurations with CDL12 speakers, ground-stacking, or flown installations using integrated rigging hardware. Ruggedly built for life on the road yet refined enough for permanent installations, the CDL18s is a professional-grade solution that elevates your low-end performance to the next level.
