The concept behind the HALO-CS was to create a compact subwoofer which would add usable low frequency information both in flown and ground-stacked configurations. As such, a powerful, high excursion 15” (381mm) neodymium drive unit was used to allow the HALO-CS to comfortably respond down to 40Hz. For larger systems, the HALO-CS can be used to add low frequency weight to the flown array with larger subwoofers providing more information in the lower octaves. The HALO-CS enclosure is the same width as the HALO Compact, and is the equivalent height of two flown or ground-stacked HALO Compact elements. Additional HALO-CS subwoofers or HALO-C elements can then be linked to the HALO-CS directly without the use of flying grids. An M20 threaded polemount adapter is provided so that when the HALO-CS sits on its rubber feet, HALO-C or other fullrange enclosures can be mounted from a distance pole above. The HALO-CS enclosure is constructed from premium 15mm (5/8”) multilaminate Birch plywood – rebated, screwed and glued together. Intelligent bracing design minimises panel flexure, thereby reducing unwanted resonance whilst still keeping the enclosure weight low. The enclosure is also supplied as standard with rubber feet on the top (for ground stacking when inverted), matching stacking recesses in the bottom of the enclosure as well as an M20 threaded polemount adapter, and two flush routed bar handles in the sides. The flying hardware is manufactured from ultra-hightensile Domex steel, finished in a polyester powder coat with aircraft-grade ball lock pins to ensure swift yet safe array assembly. A perforated steel grille backed with acoustically transparent black fabric finishes the enclosure with a sleek but stylish appearance. Two NLT4MP tour grade connectors are provided on the rear of the enclosure for input and link through. The enclosure is finished in black or white semi-matt textured paint as standard, however weather-protection options as well as custom RAL code colours are also available by request. The HALO-CS requires active high/low pass filters and a single amplifier channel capable of delivering 1000-2000W RMS into an 8 ohm load. For optimal results, either the DQ Series Advanced System Amplifiers, or the AQ or AD Series amplifiers combined with DSC48 processors should be used.
