The New L-Acoustics K3 Full Range, Compact Line Source System Is Coming Your Way

The New L-Acoustics K3 Full Range, Compact Line Source System Is Coming Your Way | XLR


Completing the K series line, K3 is a versatile loudspeaker satisfying all the requirements for mid-size events and venues from 1,000 to 10,000 people. Designed as a true full-range line source, K3 integrates 12” transducers to deliver large-format system performance but is dimensioned in a typical 10” compact format. With reduced subwoofer and amplification needs, K3 deployment is fast, straightforward, sustainable, and more economical.

K3 is ready for the events of today and tomorrow

The K3 two-way active enclosure possesses all of the hallmarks that have made K Series the reference in line array technology, including optimized mechanical design for reduced weight, laminar vents for a powerful and linear low frequency response, and time-tested effortless captive rigging.

With exceptional bandwidth for its size – 42 Hz to 20 kHz – K3 can be used as a stand-alone system boasting strong output and innate reinforced LF contour without the need of a flown companion subwoofer. For infra reinforcement and augmented LF resources, K3 can be supplemented by the KS28 subwoofer.

It also features L-Acoustics Panflex™ technology to offer a choice of four horizontal directivity patterns: 70° or 110° symmetrical or 90° asymmetrical on either side. With Panflex and inter-element angles ranging from 0° to 10°, K3 line source coverage can be precisely tailored to fit any audience geometry.

The K3 enclosure is constructed of premium grade Baltic birch plywood to ensure maximum acoustical and mechanical integrity. A thickness optimization process greatly reduces weight and maximizes robustness for touring applications.

Just like the time-tested K2, it features an ergonomic four-point captive rigging system, that integrates large handles and provides visual safety assessment. K3 transportation and rigging accessories have been designed to facilitate manipulation from truck loading to on-site deployment.

The K3 has been rated an IP55 rating which makes it suitable for outdoor operations.

Rigging & Applications

K3 can be flown with the dedicated flying frame K3-BUMP and the optional K3-BAR for greater tilt angles. The lighter K3- RIGBAR can be used to hang smaller K3 arrays or acts as a pullback accessory. K3 can be mounted on KS28 for ground stacked applications.

Ideally dimensioned to keep sightlines clear, K3 integrates easily in venues with space restrictions or complements larger K1 or K2 systems in sport facilities, festivals or large concert venues .
