L-Acoustics K1 Line Array Loudspeaker
3-way active enclosure with two weather-resistant premium 15 in transducers, four 6.5 in medium drivers and three high-output 3 in diaphragm compression driver coupled to a cylindrical waveguide with 90 degrees of horizontal directivity and 5 degrees of vertical coverage. 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 four ergonomic handles. A four-point flush-fitting hardware for rigging and combining with other loudspeakers of the same family to achieve a coherent wavefront line source. The line source directivity depends upon the number of elements and inter-element angles and can be matched to the audience geometry. Exclusively driven and protected by a proprietary amplified controller through a dedicated preset.
