PreSonus Introduces CDL12P Constant-Directivity Loudspeaker




PreSonus has introduced the new CDL12P full-range, constant-directivity, powered sound-reinforcement loudspeaker that combines the best attributes of point source and line array technology to provide the flexibility demanded by modern sound-reinforcement applications. Its constant-directivity design enables it to radiate a highly focused pattern with consistent SPL throughout the frequency-response range, both on- and off-axis.

The CDL12P is portable and can be used alone, in tandem with a subwoofer, or in an array, making it a great choice for touring bands and mobile DJs, as well as for fixed installs in small and midsize venues that don’t need a networkable loudspeaker.



Each CDL12P consists of eight 2-inch drivers aligned in a segmented circular-arc high-frequency array centered in front of a 12-inch woofer. The outputs of the low-frequency driver and the high-frequency array travel on the same acoustic axis, as with a coaxial studio monitor. A low, 420 Hz crossover frequency minimizes comb filtering. Regardless of how many CDL12Ps are stacked (up to six total), users get focused sound with consistent SPL coverage both on- and off-axis. Each CDL12P delivers 120° horizontal by 15° vertical dispersion, so six enclosures rigged together form a 120° x 90° coverage pattern.

The CDL12P’s integrated 500x500W Class D power amplifier features onboard DSP presets to facilitate and simplify arrayed configurations. The integrated DSP offers a high-pass filter; a limiter; tuning for use with PreSonus CDL18s, AIR18s, and ULT18 subwoofers; and controls for the number of enclosures used. A dual-angle pole mount is provided, supporting the use of one or two enclosures when pole-mounted on a tripod stand, or atop the companion CDL18s, ULT18, or AIR18s subwoofer, allowing the system to adapt to varying audience sizes. Heavy-duty aluminum rigging with integrated pin-loaded hardware rated for a 10:1 load ensures a safe solution for flown installations.
