A 3-way active enclosure is equipped with four 6.5-inch medium drivers, three high-output 3-inch diaphragm compression drivers, and two weather-resistant premium 15-inch transducers. These are connected to a cylindrical waveguide that has five degrees of vertical coverage and 90 degrees of horizontal directivity. 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. Four ergonomic handles are integrated within the enclosure. A coherent wavefront line source can be achieved by rigging and integrating this four-point flush-fitting hardware with other loudspeakers in the same family. The line source directivity can be adapted to the audience geometry and is dependent on the number of elements and inter-element angles. propelled alone by itself and shielded by a unique amplification controller through a dedicated preset.
