LK3 ----long throw line source


LK3 is a full range line source system designed for mid-sized mobile applications. Housing the components into a compact enclosure, LK3 is ideal for applications that require long throw, reinforced low-frequency contour, broad bandwidth and limited footprint such as live events in mid-sized festivals, and tours, performing arts, corporate events in large exhibition halls or special events. With exceptional bandwidth for its size - 42 Hz - 20 kHz - LK3 can be used as a stand-alone system boasting strong output and innate reinforced LF contour without the need of a own companion subwoofer. For infra reinforcement and augmented LF resources, LK3 can be supplemented by the LKS28 subwoofer. LK3 features to offer four horizontal directivity patterns: 70° or 110° symmetrical or 90° asymmetrical on either side. With inter-element angles ranging from 0° to 10°, a LK3 line source coverage can be precisely tailored to any audience geometry. On its own LK3 can be used as a main system for vocal and music reinforcement in most applications.Deployed with LKS28 subwoofer, LK3 is perfect as a compact main system for demanding live events.
