This install-specific 2-way passive enclosure features a weather-resistant premium 15-inch transducer and a high-output 3-inch diaphragm compression driver paired with a cylindrical waveguide with user-adjustable directivity. Constructed from premium-grade Baltic beech and birch plywood, the enclosure is protected by a coated steel grill and an acoustically transparent fabric. It includes inserts for flush-fitting connecting plates and an optional acoustically transparent front screen. The four-point hardware allows rigging and combining with other loudspeakers in the same family, creating a coherent wavefront horizontal or vertical line source. The line source directivity equals N x 30 degrees (where N is the number of enclosures in the array). It is exclusively driven and protected by a proprietary amplified controller through a dedicated preset.
