LACOUSTICS ARCS |
|
|
Overview
The ARCS® features a bi-amplified design, an advanced enclosure tuning with a custom DOSC® waveguide for a
remarkable clarity and coherence. When arrayed, ARCS® radiates a constant curvature wave front of 22.5° x the number of enclosures. Vertically, the enclosure provides an asymmetrical
coverage of 60° (- 20° by + 40° of site angle).
The system can be arrayed both horizontally and vertically to fulfill multiple application requirements in terms of audience geometry, type of event and program material. When combined with
the SB28 subwoofer, ARCS® delivers an extended LF contour with added impact. Whether permanently installed, on the road as a standalone FOH system or a complement to another WST® line
source, ARCS® naturally deploys all the power of WST®, offering a unique near-field listening experience throughout the audience.
