Increased SPL and lower weight promised by L-Acoustics Arcs II

Following in the footsteps of a much-loved loudspeaker, L-Acoustics has debuted its new Arcs II constant curvature line source enclosures. The two-way, active loudspeakers are intended for medium to large productions or installations and reportedly boast a number of improvements on their popular predecessors including the manufacturer’s Wavefront Sculpture Technology.

Other improvements include the incorporation of K1 grade transducers for increased SPL (140dB), and a lower weight of 50kg, while a new front grille has been added for enhanced durability. The enclosures are driven by a single factory preset to increase efficiency.

An Arcs II line source can be deployed either horizontally or vertically, with a coverage angle proportional to the number of enclosures in the array (N x 22.5-degrees). The orientation of the enclosures within an array determines asymmetric distribution, allowing the use of a horizontal Arcs II line source either for upward or downward coverage. The enclosures can be deployed as a tightly packed FOH system for rooms requiring medium throw, while other applications include distributed systems, use as a centre cluster in theatres, as a side-fill monitoring solution, and as a flown or stacked centre fill, stereo front fill, or offstage fill.

The La-Rak touring rack and the LA8 amplified controller preset library deliver an advanced and precise drive system for Arcs II. Additional features include an L-Drive two-way transducer protection circuit (peak and RMS limiting) and an array morphing EQ interface.
