• XLD281, White, Line Array Element, 2 x 8", 2 x ND2, 120 DEG x 10 DEG
• The XLD 281 is the core element for constructing X-Line Very Compact systems. The XLD281 is a 3-way design using CCT (Coverage Control Technology) to control horizontal coverage to 250Hz.
• It uses an 8" neodymium LF transducer, an 8" neodymium LF/Definition of MB:] body=[The megabyte is a multiple of the unit byte for digital information storage or transmission with two different values depending on context: 1048576 bytes (10242) generally for computer memory; and one million bytes (106, see prefix mega-) generally for computer storage. The IEEE Standards Board has decided that "Mega will mean 1 000 000", with exceptions allowed for the base-two meaning. In rare cases, it is used to mean 1000x1024 (1024000) bytes. It is commonly abbreviated as Mbyte or MB (compare Mb, for the megabit).] cssheader=[boxoverheader] cssbody=[boxoverbody]">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 Definition of Bandwidth:] body=[Literally, bandwidth is a frequency span. Beyond that definition, its meaning will depend somewhat on context. For example, the bandwidth of a bandpass filter is the upper cutoff frequency minus the lower cutoff frequency (cutoff frequency being the filter's -3 dB point). The audio bandwidth is generally given as 20 Hz to 20,000 Hz, although there are harmonic components of audio that extend far above the 20k point. In most situations where bandwidth is given as an audio spec, the wider the frequency range the better. Be sure that when comparing bandwidth on different devices, that the same spec is being expressed. For example, some effects devices cite their bandwidth spec based on the dry, or unprocessed signal, while others give the bandwidth of the actual processed sound. These difference between these two specs (both listed as "bandwidth") can be substantial.] cssheader=[boxoverheader] cssbody=[boxoverbody]">bandwidth while controlling horizontal beam width to 250 Hz by using DSP. The XLD281 can be used in tri-amp mode, or in Definition of Bi-Amp:] body=[Bi-Amp, short for "bi-amplification." A two-way audio system in which the signal is divided by frequency into two signals that are independently amplified and fed to separate speaker system components (e.g., woofers and tweeters). In a "tri-amped" system, signals are divided by frequency into three individually amplified groups.] cssheader=[boxoverheader] cssbody=[boxoverbody]">bi-amp using a sophisticated internal passive network.
• Designed for use in arrays of four or more elements, the XLD281 delivers full Definition of Bandwidth:] body=[Literally, bandwidth is a frequency span.

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.
