[. . . ] It is comprised of the models; XLD281 full range, XLE181 full range, and the XS212 sub woofer. [. . . ] It uses a 8" neodymium LF transducer, a 8" neodymium LF/MB transducer, and two neodymium 2" voice coil compression drivers combining through 2 hydra plane wave generators into a 120° x 10° waveguide. CCT uses both 8" transducers to provide maximum low frequency output and operating bandwidth while controlling horizontal beam width to 250 Hz by using DSP. The XLD281 can be used in tri-amp mode, or in bi-amp using a sophisticated internal passive network. Designed for use in arrays of four or more elements the XLD281 delivers full bandwidth audio with precise, predictable coverage control. XLVC delivers unprecedented performance in applications ranging from live reinforcement to performing arts venues, to houses of worship. Technical Specifications: Freq.
