A 2-way passive enclosure featuring two weather-resistant premium 6.5-inch transducers and a high-output 1.75-inch diaphragm compression driver, coupled to a cylindrical waveguide with 110-degree horizontal and 15-degree vertical coverage. The cabinet is made from moisture-resistant composite material, with a composite grille and acoustically transparent fabric protecting the front. It includes two integrated handles and a three-point captive hardware system for rigging and combining with other loudspeakers in the same family to form a coherent wavefront line source. The directivity of the line source is adjustable based on the number of elements and inter-element angles to match audience geometry. It operates exclusively with a proprietary amplified controller using a dedicated preset for optimal performance and protection.
