Description Low-end punch that never makes you guess. A terrific complement for any full-range loudspeaker and the perfect companion for the PreSonus® CDL12 Constant Directivity loudspeaker, the CDL18s delivers a tight, coherent low-end, driven by an integrated 1000-watt Class D power amp, and features a unique ported design that maximizes efficiency in a compact form-factor. The Dante®-enabled CDL18s provides the articulate sub-bass frequency reproduction demanded by audio professionals thanks to its custom 18-inch low-frequency transducer with 4-inch voice coil, providing 7 mm of driver travel before over-excursion to move more air for a low-end punch you can feel. When flown together in a vertical array, or combined for ground-stacked applications, the CDL18s and CDL12 form a complete, coherent loudspeaker system with an even response across the frequency spectrum.
