A 2.5-inch diaphragm compression driver with high output and a weather-resistant quality transducer attached to a cylindrical waveguide with user-adjustable directivity powers this 2-way passive enclosure. The enclosed cabinet is made of Baltic beech and birch plywood of the highest caliber. A coated steel grill and an acoustically transparent cloth shield the front of the enclosure. Two ergonomic grips and panel corner stops are integrated into the enclosure to protect it. In order to create a coherent wavefront line source, the flush-fitting hardware enables rigging and combining with other loudspeakers in the same family. N x 10 degree, where N is the number of enclosures in the array, is the line source directivity. driven solely by a specialized amplified controller that is secured by a preset.
