XLD281
3-Way, High-Output,
Very Compact
Line-Array Element
General Description:
EV engineers have defined a new group of Very Compact
line array elements, XLVC. It is comprised of the models;
XLD281 full range, XLE181 full range, and the XS212 sub
woofer. The XLD281 is a 3 –way design using CCT (Coverage
Control Technology) to control horizontal coverage to 250
Hz. 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. Integrated rigging with hinge
points located correctly between array elements is simple to
use and quickly provides uncompromised line array
performance. Ground stacking is easily done using Array
Rails or subwoofers as the array base.

Most applications using flown very compact elements require
subwoofers integrated into the same array as the full range
systems. XLVC provides two methods to conveniently do
this. The XS212 sub woofer module has the same rigging
foot print as the XLD281 allowing it to be directly arrayed
above, or below XLD281 full range systems. Where vertical
space is limited sub woofer arrays can be created and flown
behind the XLD281 full range array using an additional grid
and a Coupler Beam. LAPS modeling software quickly
provides array configurations and rigging information.

XLVC delivers unprecedented performance in applications
ranging from live reinforcement to performing arts venues,
to houses of worship.
