Install-specific 2-way passive enclosure featuring a weather-resistant premium 10-inch transducer and a high-output 2.5-inch diaphragm compression driver, paired with a cylindrical waveguide offering user-adjustable directivity. The enclosure is crafted from high-quality 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 system 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). It is exclusively driven and protected by a proprietary amplified controller with a dedicated preset.
