Community Professional Loudspeakers’ Entasys ENT220 two-way compact column array loudspeaker has a frequency response of 80Hz to 22kHz and a maximum peak output of 130dB SPL peak. The extruded paintable PVC enclosure houses 20 80mm low-frequency long-excursion mylar drivers and four, three-element Compact Ribbon Emulators. Vertical coverage is 15 degrees and horizontal coverage is 140 degrees. The system provides for 8Ω or 70V/100V operation.
Featuring 32 4in. transducers, Duran Audio’s AXYS Intellivox-DS500 is one tall loudspeaker, standing less than 195in. tall. Digitally steerable and capable of synthesizing a 3D radiation pattern, the array is powered by 16 40W Class D amplifiers and using onboard DSP and DDS (Digital Directivity Synthesis). As such, the coverage pattern is 130-degrees horizontal with a variable vertical coverage. The frequency range is 130Hz to 10kHz and peak SPL is 100db.
The EAW LS832 employs eight 4in. woofers and three 1in. soft-dome tweeters mounted on a baffle with a slight convex arc. The coverage provided is 140 degrees horizontal x 20 degrees vertical with a frequency response of 200Hz to 20kHz. The calculated full range peak output is 126dB SPL. Designed for permanent install, connections are affected via a two-terminal barrier strip and six 1/4in., 20 threaded mounting points are integrated into the Baltic birch plywood enclosure.
At just a little more than 6.5ft., JBL’s new CBT 200LA-1 is tall. Comprising 32 2in. drivers in two modules, the system provides vertical pattern coverage that is switchable between 30 and 15 degrees with a symmetrical pattern or an asymmetrical progressive-gradient coverage that is narrower at the top and broader at the bottom of the array. The voicing is adjustable via a music/speech setting switch. The frequency range is 80Hz to 20kHz, and maximum SPL is 129dB (in speech mode and narrow vertical coverage).
The K-Array KP52 3D line array element variable beam speaker provides a variable vertical coverage selectable between “spot” (10 degrees) and “flood” (45 degrees). The horizontal coverage is 90 degrees. The weatherproof system can be used for outdoor applications. The frequency range is 100Hz to 20kHz with a maximum peak SPL of 128.
Meyer Sound’s CAL (Column Array Loudspeaker) is a self-powered system that offers vertical coverage that is variable from five to 30 degrees, with beam steerage up or down 30 degrees. The horizontal coverage is 120 degrees. The CAL 96 uses 24 4in. drivers and 72 20mm tweeters, each with their own Class D amplifier. The operating frequency range is 100Hz to 16 kHz, and the maximum peak SPL is 106dB.
