RIGGING SYSTEM COMPONENTS

The system approach developed by L-ACOUSTICS

consists in providing packaged solutions for loudspeaker system in

order to guarantee the highest and most predictable level of performance at any step: modeling, installation, and

operation. An L-ACOUSTICS

loudspeaker system is the set of components available to form any loudspeaker system

based on one of the full-range loudspeaker enclosure afforded by L-ACOUSTICS

®.

It includes enclosures, rigging

accessories, loudspeaker cables, amplified controllers, and software applications.
The main components involved in the rigging process of an

ARCS

WIDE SYSTEM
