The XLD291 is a 3 -way design using CCT (Coverage Control
Technology) to control horizontal coverage to 200 Hz. It uses an 8"
neodymium LF transducer, an 8" neodymium LF/MB transducer,
and two neodymium 2" voice coil compression drivers combining
through 2 hydra plane wave generators into a 90° x 10° waveguide.
CCT uses both 8" transducers to provide maximum low frequency
output and operating bandwidth while controlling horizontal beam width to 200 Hz by using DSP. The XLD291 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 XLD291
delivers full bandwidth audio with precise, predictable coverage control. Integrated rigging with hinge points located correctly between array elements is simple to use and quickly provides uncompromised line array performance. Groundstacking is easily done by using EV's XGS-4 Groundstack Kit for XLVC.
The XLVC family consists of two full-range systems with dual woofers, two full-range systems with single woofers and a subwoofer system. The dual-woofer versions include the XLD281 with a 120° horizontal coverage pattern and the XLD291 with a 90° horizontal coverage pattern. The single-woofer versions include the XLE181 with a 120° horizontal coverage pattern and the XLE191 with a 90° horizontal coverage pattern. The subwoofer module is the XS212. Most applications using flown very compact elements require subwoofers integrated into the same array as the full range systems. XLVC provides three methods to conveniently do this. The XS212 sub woofer module can be directly arrayed above, or below XLD291 full range systems. Where vertical space is limited sub woofer arrays can be created and flown behind the XLD291 full range array using an additional grid and EV's CBEAM (Coupler Beam). LAPS modeling software quickly provides array configurations and rigging information. Using the AGCD Adapter Grid, XLD cabinets can also be flown or groundstacked with the XLC215 dual 15-inch subwoofer.
XLVC delivers unprecedented performance in applications ranging
from live reinforcement to performing arts venues, to houses of
