2-way active enclosure with two weather-resistant premium 12 in transducers and high-output 4 in diaphragm compression driver coupled to a cylindrical waveguide with user-adjustable horizontal directivity and 10° of vertical coverage. The enclosure cabinet is constructed of premium grade Baltic birch plywood. The enclosure front is protected by a coated steel grill and an acoustically transparent fabric. The enclosure integrates two ergonomic handles. A four-point captive hardware allows rigging and combining with other loudspeakers of the same family to achieve a coherent wavefront line source. The L-Acoustics K3 provides outstanding sound quality. The line source vertical directivity depends upon the number of elements and inter-element angles. Horizontal directivity can be adjusted to four settings to match any audience geometry: 110°, 70° and 90° asymmetric on either side. Exclusively driven and protected by a proprietary amplified controller through a dedicated preset.
