L-Acoustics Arcs II Constant Curvature 2-Way Active Speaker Cabinet

Description: The ARCS II has been designed for medium to large productions, and bills itself as offering an incomparable listening experiences for audiences, boasting of unsurpassed precision, clarity and impact.ARCS II is a bi-amplified enclosure that adheres to the 2-way active design, yet it comes with a number of improvements over earlier models, the most notable being the inclusion of K1 grade transducers that offer increased SPL along with a lower weight. In addition, the ARCS II is built with endurance in mind, coming with a new and improved front grill design that not only looks good but also afford the enclosure a much longer shelf-lifeThe driving force behind the ARCS II is the LA* amplified controller with LA-RAK Touring Rack. The ARCS II constant curvature line source is optimized for medium throw applications. Boasting K1-grade drivers in a 2-way active enclosure, ARCS II delivers very high SPL levels, native low-frequency performance and constant tonal balance over distance. ARCS II is simple to use, with its constant curvature design and is particularly recommended for indoor L/C/R applications, medium-sized outdoor festivals or as a fill complement to large K systems.In the enclosure coupling plane, the razorsharp SPL off-axis rejection is used to avoid reflecting surfaces. In the perpendicular plane, the smooth SPL roll off and asymmetric directivity of ARCS II can be used to maximize stereo imaging and perfectly adjust to the audience geometry. The ARCS II features one 15’’ neodymium LF driver in a bass-reflex tuned enclosure and one 3’’ neodymium diaphragm compression driver coupled to a DOSC® waveguide.The ARCS II is based on an active 2-way design with a nominal impedance of 8 ohms for both the HF and the LF section.The ARCS II cabinet is made of first grade Baltic birch plywood to ensure maximum acoustical and mechanical integrity.The ARCS II enclosure operates over the 50 Hz to 20 kHz nominal frequency bandwidth. This response can be lowered down to 25 Hz with the addition of the SB28 subwoofer.The DOSC® HF waveguide generates a 22.5° symmetric x 60° asymmetric (-20°/+40°) directivity pattern. These values correspond either to the horizontal x vertical coverage angles, for an ARCS II enclosure standing vertically, or to the vertical x horizontal coverage angles, for an ARCS II enclosure in the radial orientation.The ARCS II rigging system allows assembling a horizontal or vertical array with a constant curvature. The DOSC® waveguide in the HF region allows the system to be arrayed without breaking the inter-element acoustic coupling. The WST® (Wavefront Sculpture Technology) criteria are then fulfilled, so that such an array can be qualified as a true line source. An ARCS II line source provides a smooth tonal response and a coverage that is free of secondary lobes over the entire frequency range.The ARCS II enclosure is exclusively driven and bi-amplified by the LA8 amplified controller. This one ensures active system linearization, intelligent transducer protection, and optimization for the loudspeaker system. With a single factory preset designed to be used in the different operation modes of the ARCS II, the performance of the system will depend upon the choice of the physical system configuration.SpecsUsable bandwidth (-10dB): 50 - 20k Hz (ARCS II present)Nominal directivity (-6dB): Horizontal: symmetrical 22.5° Vertical: 60° asymmetric (-20°/+40°)Maximum SPL: 140 dB ([ARCS II] preset)RMS Power handling capacity: LF: 600 W, HF: 100 WComponents:LF: 1 x 15" neodymium weather-resistant with 4’’ coilHF: 1 x 3" neodymium diaphragm compression driverNominal impedance: LF = 8 ohms, HF = 8 ohmsRiggingLIFTBAR certified for 6 ARCS II in a horizontal arrayARCBUMP certified for 4 ARCS II in a vertical arrayPhysical data:W/w x H x D: 439/190 x 820 x 652 mm17.3/7.5 x 32.3 x 25.7 inWeight (net): 50 kg / 110 lbsConnectors: 2 x 4-pin SpeakON®Cabinet: Baltic birch plywoodFinish: Grey brown, RAL 8019®Front: polyester powder-coated steel grill Airnet® acoustically neutral fabricRigging elements: steel with dual coating (zinc and polyester powder)
