‘A no compromise tool’: L-Acoustics reveals new compact K3 line source system

L-Acoustics has added to its K-Series with the new K3 line source system, the firm’s smallest full-range enclosure to date.

Designed for use in mid-size events with audiences ranging from 1,000 to 10,000, the K3 is designed to provide full-range bandwidth, without the need for a flown companion subwoofer.

“K3 is ready for the events of today and tomorrow,” said L-Acoustics executive director of application design Florent Bernard. “Our design team created a dual-12-inch-based system with the form factor and price of a 10-inch design, without the inherent performance compromises of 10-inch loudspeakers. K3 offers long-throw, full-range performance in a compact, accessible package, tailor-made for small to mid-capacity events and venues that are the mainstay of most sound providers. It is a ‘no compromises’ tool, perfectly adapted to the current event landscape and, when paired with K1 and K2, is quickly and powerfully scalable for large-capacity events.”

Providing the full-range L-Acoustics contour from an enclosure that is 33 per cent smaller than the K2 and weighing just 43 kg (95 lbs), K3 is suited to applications that require power and bandwidth from a small form factor, including mid-size tours, festivals, corporate events, religious services and other productions.

The new two-way active WST enclosure features an optimised mechanical design for reduced weight, laminar vents for powerful and linear low frequency response, and simple rigging. It also incorporates L-Acoustics Panflex technology, which provides sound designers with quick access to 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 tailored to fit any audience geometry.

The L-Acoustics signature DOSC waveguide offer long-throw capability (>35 m/100 ft), providing bandwidth of 42 Hz to 20 kHz (-10 dB, 70° directivity) and maximum SPL of 143 dB. The K3 can be used as the main system for vocal and music reinforcement in most applications, or as a complement to K1 or K2 as outfills or delays.

The new product’s system design meets today’s requirement for more sustainable deployment and reduced truck space. One LA12X amplified controller can power up to six K3, meaning that a single LA-RAK AVB unit can drive up to 18 K3.

The L-Acoustics K3 is shipping immediately, with a K3i model for fixed install applications will be released in 2021.
