This install-specific 2-way passive enclosure features a weather-resistant premium 15-inch transducer and a high-output 3-inch diaphragm compression driver, coupled to a cylindrical waveguide with user-adjustable directivity. The cabinet is constructed from premium grade Baltic beech and birch plywood, with a front protected by a coated steel grill and acoustically transparent fabric. It includes inserts for flush-fitting connecting plates and an optional acoustically transparent front screen. The four-point hardware allows for rigging and combining with other loudspeakers of the same family, creating a coherent wavefront line source. The line source directivity equals N x 10 degrees, where N is the number of enclosures in the array. This system is exclusively driven and protected by a proprietary amplified controller through a dedicated preset.
