Install-specific 2-way passive enclosure with a weather resistant premium 15 in transducer and high output 3 in diaphragm compression driver coupled to a cylindrical waveguide with user-adjustable directivity. The enclosure cabinet is constructed of premium grade Baltic beech and birch plywood. The enclosure front is protected by a coated steel grill and an acoustically transparent fabric. The enclosure integrates 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 to achieve a coherent wavefront horizontal or vertical line source. The line source directivity is equal to N x 30 degree (where N is the number of enclosures in the array). Exclusively driven and protected by a proprietary amplified controller through a dedicated preset.
